This is a blog post about troubleshooting a hydraulic vane pump. Most of the people who use this kind of pump know what they are doing and how to fix them when something goes wrong, but for those that don’t, it could be very confusing.
Problems on shafts
There are many problems that hydraulic vane pumps can experience on their shafts. A few possible causes of these problems are listed below. If you are experiencing one of these issues, it is important to take action and troubleshoot the issue as soon as possible.
-Fluid leaks
-Shaft misalignment
-Damaged or bent shaft
-Worn or degraded gears
Cartridge screws not properly mounted
If you are having trouble with your hydraulic vane pump, there is a chance that the cartridge screws are not properly mounted. In order for the vane to move up and down, the screws must be tight against the cylinder. If they are not tight, the vane can move around on the screw and cause it to wear out quickly. To check if the screws are properly mounted, remove them and examine them closely. If they are loose, tighten them using a wrench.
Hollow push pin wrongly mounted
If you are experiencing problems with your hydraulic vane pump, there is a good chance that the push pin that is used to hold the vane in place is incorrectly mounted. This could cause the pump to not function correctly, or it could even cause the vane to break off. To check if the push pin is correctly mounted, you can remove it and see if the vane moves freely when the pump is activated. If it does not, then the push pin may be installed incorrectly and should be replaced.
Loose fasteners
Hydraulic vane pumps are used in a variety of industries to move fluid and gas. They can be found on agricultural equipment, trucks, and boats. Because hydraulic vane pumps are used in wet environments, they can be susceptible to water and debris damage.
Here are some common hydraulic vane pump troubleshooting tips:
1. Check the fasteners that hold the hydraulic vane pump in place. Loose fasteners can cause the pump to fail. Check the fasteners for tightness, corrosion, and wear. If any of these conditions exist, replace the fastener.
2. Clean the area around the pump where debris may have collected. This will help prevent damage from debris accumulation.
3. Check the fluid level in the hydraulic vane pump reservoir. If the reservoir is low on fluid, it may not be able to operate properly. Add fluid to the reservoir as needed.
4. Check for clogged filters or lines. If clogged filters or lines are found, they will need to be cleaned or replaced.
Marks on port plates
Marks on port plates can indicate several things. If the marks are new and have not been there before, they could be from a foreign object entering the vane pump and getting caught on the port plates. Another possibility is that the pump is not lubricated properly and is wearing down the port plates prematurely.
If the marks are old and have been present for some time, it could mean that debris has built up on the port plates and is preventing them from operating as they should. In either case, it’s important to take a look at the port plate assembly and make any necessary repairs or adjustments.
Fretting corrosion
Hydraulic vane pumps can be a reliable and efficient tool in your workshop, but like any other mechanical device they can become malfunctioned. When this happens, the pump may not be able to move fluid efficiently or at all. In some cases, the problem may be attributable to fretting corrosion, which is a type of wear caused by metal-to-metal contact. Here are some tips for troubleshooting hydraulic vane pumps that are experiencing fretting corrosion:
1. Check the oil level and make sure it is at its minimum recommended level. Fretting corrosion is often accompanied by a decrease in oil pressure, so keeping the oil levels low can help to prevent the issue from becoming worse.
2. Inspect the bearings and seals for signs of wear or damage. If the bearings or seals are in bad condition, they may be contributing to the issue with the pump.
3. Check the impeller for excessive wear or damage. If there is excessive wear on the impeller, it may be causing problems with fluid flow.
4. Check for clogging in the piping system and check for any debris that may be blocking passages. If debris is found blocking passages, it will need to be removed to allow for proper lubrication.
Shaft splines/keyed shaft worn
Hydraulic vane pumps are a common piece of machinery in many industries. They are used to move fluids, such as water or oil, and can be found in industrial settings, such as power plants and refineries. Because hydraulic vane pumps are so common, they are also susceptible to occasional malfunctions.
If your hydraulic vane pump is not working correctly, there are a few things you can do to troubleshoot the issue. check the fluid levels in the tank and cylinder. If the fluid levels are correct, then check the seal around the shaft splines. If the seal is damaged or worn, then the pump may not be able to transfer enough fluid to operate correctly. Additionally, if the pump is not transferring fluid at all, it may be due to a faulty motor or gearbox. In these cases, it may be necessary to replace the entire pump assembly.
Fatigue shaft rupture
Hydraulic vane pump troubleshooting is critical when the pump fails and causes a loss of circulation. Failure to properly diagnose and correct the issue can lead to catastrophic results.
In this blog post, we will focus on three common hydraulic vane pump failures and discuss the necessary steps for troubleshooting each one. By following these steps, you can save both time and money by avoiding costly repairs.
1. Fatigue shaft rupture: When a section of the shaft’s metal becomes too fatigued from repeated use, it can break under the strain of the hydraulic pressure. This can happen either from overuse or from a sudden event such as a drop in temperature. If you notice that your pump is struggling to circulate fluids, be sure to inspect the shaft for signs of fatigue. If there is damage, take steps to replace the shaft as soon as possible.
2. seized bearing: A seized bearing is when the ball or roller bearings that allow your pump to move are not able to turn freely. This can happen if debris has built up in the bearings or if they have become misaligned due to wear or abuse.
Bush/bearing problems
Hydraulic vane pump problems are typically due to one of two things: a bad bush or bearing, or a failed hydraulic oil reservoir. In either case, there are a few quick and easy steps you can take to get your vane pump back up and running as quickly as possible.
If you’re able to isolate the issue to a specific part, it’s often best to troubleshoot that part before moving on to the next step. However, if the failure is systemic and affects multiple parts, then it’s usually best to replace the entire vane pump assembly. Here are some tips for troubleshooting each of these scenarios:
Bad Bush/ Bearing: If you’re able to identify which part is causing the problem, start by testing that part using basic tools like a voltmeter. If the part is defective, it will likely show signs of low voltage when tested this way. Next, try replacing the part with a known good one and see if the problem resolves. If not, it’s likely time for a newbush/bearing.
Marked cam ring
Hydraulic vane pumps are used in a wide variety of applications, from water pumps to agricultural equipment. Like any other mechanical device, hydraulic vane pumps can experience problems. In this article, we’ll discuss some common hydraulic vane pump troubleshooting issues and how to fix them.
Shaft seal loosing contact
If your hydraulic vane pump is not working, one possibility is that the shaft seal has lost contact with the shaft. To test this, remove the shaft from the pump and check for leaks around the shaft seal. If there are leaks, install a new shaft seal and re-install the pump. If there are no leaks, the shaft seal is likely worn and you will have to replace the pump.
Dissymmetrical wear on the port plates
Hydraulic vane pump troubleshooting can be a daunting task if you don’t understand the basic concepts behind them. In this post, we’ll discuss some of the most common dissymmetrical wear problems and how to fix them.
We’ll also cover some of the signs that your hydraulic vane pump is in trouble. If you’re experiencing any of these symptoms, it’s important to get your pump serviced as soon as possible.
Broken dowel pin
Broken dowel pin can be the result of a variety of causes, such as overuse, improper installation, or tampering. In most cases, it is not necessary to replace the entire pump assembly. Here are four steps to troubleshooting a broken dowel pin:
1. Check the fluid level. If the fluid level is low, add more fluid until the pump is operating correctly.
2. Check for power/ground continuity. If power and ground continuity are not present, replace the electrical connector or switch.
3. Inspect the pump for damage. If there is significant damage to the pump, it may need to be replaced.
4. Inspect the dowel pin for wear or damage. If there is wear or damage on the dowel pin, it may need to be replaced.
Noisy pump
A noisy hydraulic vane pump can be a sign of a more serious issue. If the noise is constant and intensifies when the pump is running, it may be a sign that something is wrong with the pump or the system it’s operating in. In most cases, these issues can be fixed by taking some simple steps. If the noise is intermittent or sporadic, however, it may be indicative of a more serious problem and may require professional assistance.
Parallel marks on the port plate
Hydraulic vane pumps are used in a variety of applications, and their proper operation is essential to ensure smooth flow and optimum performance. When encountering trouble with a hydraulic vane pump, it’s important to troubleshoot the issue as quickly as possible to prevent further damage or loss of productivity.
One common issue with hydraulic vane pumps is parallel marks on the port plate. This occurs when the pump’s impellers are not spinning in unison, which causes the liquid being pumped to flow in stripes across the port plate instead of in a continuous stream.
To fix this problem, you need to determine which component is causing the imbalance. In many cases, this will be a component on the pump’s drive train, such as a belt or pulley. If that isn’t the cause, then you may need to replace the pump altogether.
Pressure overshoot
Hydraulic vane pumps are a common type of pump used to move fluids. When operating correctly, these pumps should produce a consistent output pressure regardless of the volume of fluid being pumped. However, if there is an issue with the pressure overshoot that is causing the pump to produce an incorrect pressure, then it can lead to damage to the equipment and possible injury.
If you are experiencing problems with your hydraulic vane pump, there are a few things that you can do to try and diagnose the issue. First, you can check the operational specs for your pump to make sure that it is operating within normal parameters. If the pump is failing to produce an acceptable output pressure, then you will need toevaluate the potential causes of the overshoot.
One potential cause of pressure overshoot on hydraulic vane pumps is a worn or damaged component. If the component is causing excessive wear on the pump, this will lead to an overshoot in pressure. Additionally, if the component is not functioning properly due to wear or damage, this will also result in an overshoot in pressure.
Instant pressure overshoot
Hydraulic vane pump troubleshootingIf you are experiencing an instant pressure overshoot with your hydraulic vane pump, there are a few things you can do to troubleshoot the issue.
1. be sure that the fluid level in the vane pump is correct.
2. make sure that the vane pump is properly installed and functioning.
3. check for any clogs or blockages in the system.If the fluid level in the vane pump is correct, then it is likely that there is a problem with the installation or functioning of the pump.
To check for clogs or blockages, you can try using a plunger to clear any obstructions from the system. If this does not solve the problem, you may need to replace the vane pump.
Cycled overpressurization
Hydraulic vane pumps are usually reliable, but can experience problems with cycling overpressurization. When this happens, the pump can overheat and fail. Here are some tips for troubleshooting hydraulic vane pump cycling overpressurization.
1. Check the pressure gauge. If the gauge is reading high or low, it may be indicating that the pump is cycling overpressurization.
2. Check the oil level. If the oil level is low, it may be causing the pump to overheat. Add more oil to the system as needed.
3. Check the fan belt. If the fan belt is worn or defective, it may be causing the pump to overheat. Replace the belt as needed.
4. Check for blockages in the system. a clogged filter, valve, or pipe can cause cycling overpressurization in a hydraulic vane pump. Clear any obstructions and try again.
Pressure gradients
Hydraulic vane pumps are used extensively in industrial and agricultural applications. These pumps are capable of generating high pressure and flow rates, which can result in failures if not operated properly. Here are some tips for troubleshooting hydraulic vane pump problems.
1) Verify that the pump is operating correctly by checking the pressure and flow rates.
2) Check for leaks by using a pressure meter to measure the amount of pressure lost from the system.
3) Verify the alignment of the vanes by measuring the distances between each vane and the housing.
4) If a problem is found, try to eliminate it by adjusting one or more of the above parameters.

Start-up without a proper air bleed-off
Hydraulic vane pumps are used in a variety of applications, but they can be problematic if the air bleed-off is not properly configured. One common issue with these pumps is that the startup sequence can be disrupted without proper air flow. This can cause difficulties in starting the pump and may even result in damage. In some cases, this issue can be resolved by reconfiguring the air bleed-off or by using a different type of pump.
Air contamination – Fluid foaming
Hydraulic vane pumps are used to move fluid, such as water or oil, through a system. They use the Bernoulli principle to move the fluid through the pump. This principle states that when a fluid is forced from a higher pressure to a lower pressure, the pressure difference causes the fluid to move in a circular motion. This motion is called a vortex. When air gets into the vortex, it can cause the pump to malfunction. Here are some tips on how to troubleshoot hydraulic vane pump problems caused by air contamination:
1) Check for leaks: If there are any leaks in the system, air will be entering and causing the problems with the pump. Look for signs of leakage, such as bubbling or foaming around the system. If there are any signs of leakage, seal them up as soon as possible.
2) Check for blockages: If there are any blockages in the system, air will be flowing through them and causing the problems with the pump. Use a snake or an auger to clear any blockages if possible. If not, try pumping manually until the issue is resolved.
Solid particle contamination
Hydraulic vane pump troubleshooting can be difficult if you have solid particle contamination. The first step is to determine the source of the contamination. If it’s coming from the hydraulic vane pump, then the problem is likely with the pump itself. If the contamination is coming from outside the hydraulic vane pump, then you’ll need to take additional steps to clean up the area.
Water contamination
Hydraulic vane pump systems are often used in industrial and commercial settings where water must be kept clean and free of contaminants. Unfortunately, these pumps can also be susceptible to contamination. When the hydraulic vane pump is not performing as it should, there are a few things to check first.
One common cause of hydraulic vane pump problems is water contamination. If the system is unable to remove all of the contaminants, this will cause clogs and reduced performance. It is important to check for signs of water contamination before doing any repairs or replacements on the pump system. Some signs that water contamination may be present include:
-Foul odor
-Flooding
-Low pressure readings
-Inability to clear debris
Viscosity failures
Hydraulic vane pump failures can be caused by a number of factors, including improper lubrication, clogged nozzles, and worn or misaligned parts. In many cases, however, the problem can be traced back to a failure in the viscosity control system. Here are some tips for troubleshooting hydraulic vane pump failures:
1. Check the oil level and flow rate: Keep the oil level high and the flow rate low by using a low-viscosity oil. If the flow rate is too high, it can cause wear on the bearings and seals.
2. Check for clogged nozzles: Clear any blockages with a plunger or snake before proceeding. If no obstruction is found, check for rubbing or scoring on the inside of the nozzle tip. If these are present, it may be necessary to replace the nozzle.
3. Check for worn or misaligned parts: Replace any worn or misaligned parts with new ones before proceeding. This will ensure proper viscosity control and prevent further pump failures.
Unsuitable fluids
Hydraulic vane pumps are used in a variety of industries to move liquids and gases. When they are working properly, these pumps can move large amounts of fluid quickly and efficiently. However, if the pump is not working as it should, it can be difficult to determine the cause. In this article, we will discuss some common hydraulic vane pump troubleshooting issues and how to fix them.
One of the first things you should do when diagnosing a hydraulic vane pump problem is to check the fluids that it is using. Many pumps are designed to work with specific types of fluids, so if the fluid is not compatible with the pump, it will not work properly. If the fluids are compatible, but the pump is not functioning correctly, there may be an issue with the mechanics of the pump. In either case, you will need to consult a professional for help diagnosing and repairing the problem.
Unsuitable grease
If the hydraulic vane pump is not working, it’s likely due to an unsuitable grease. Make sure the grease is properly applied to the vane and that it is free of any debris. If the grease is still not working, try replacing the vane.

What are the common hydraulic vane pump problems?
Hydraulic vane pumps are one of the most commonly used types of pumps in industrial and commercial applications. They are used to move fluid, such as water or oil, up or down a pipeline. When they fail, they can cause big problems.
Here are some of the most common hydraulic vane pump problems:
Broken or clogged impellers: One of the most common problems with hydraulic vane pumps is broken or clogged impellers. This can happen when the pump is overloaded or when the impellers become worn out over time.
Lack of fluid flow: If there is not enough fluid flow through the pump, it will not be able to move the required amount of fluid. This can be due to a broken pipe, clogged impellers, or a faulty motor.
Overheating: If the pump overheats, it can cause damage to itself and surrounding equipment. Overheating can also lead to a loss of fluid pressure, which can cause the pump to stop working altogether.
rotary vane pump troubleshooting
A rotary vane pump is a type of reciprocating pump that uses a rotating blade to move fluid. This type of pump is used in industrial and commercial applications, such as water treatment and drainage. Rotary vane pumps can be difficult to troubleshoot and repair, due to their intricate mechanisms. In this article, we will discuss some common problems with rotary vane pumps and how to fix them.
If you are experiencing issues with your rotary vane pump, start by checking the fluid level and the impeller. If the fluid level is low or the impeller is not turning, the problem may be with the motor or the gearbox. If the fluid level is high or the impeller is turning, the problem may be with the housing or the blades. Finally, if none of these solutions work, it may be necessary to replace the pump.

rotary vane vacuum pump troubleshooting
Hydraulic vane pump troubleshooting is a tricky process, but with the help of a diagram and some simple steps, you can fix most common issues. Follow these tips to keep your vacuum pump running smoothly:
1.Make sure all hoses and connections are tight. Loose connections can cause your pump to overheat and fail.
2.Inspect the blades for any damage or wear. If the blades are damaged or worn, they may not be able to move the fluid efficiently and could cause your pump to overheat or fail.
3.Check the vacuum pressure gauge to ensure that it’s reading correctly. A low vacuum pressure can mean that either the pump is not working properly, or there is something blocking the fluid flow.
4.Turn off the power to your pump and check for any clogs in the lines or valves. If you find any clogs, remove them using a plunger or a pipe cleaner before turning on the power again.
Is vane pump too small to be used with larger than 10 mm tubing?
vane pump does in fact support use with tubing up to 10mm. It’s easy to convert a vane pump system that you are using with larger than 10mm tubing into one that would accommodate the smaller tubing. It just requires connecting the main line to the output port of the pump, and then connecting the output port of the pump to any chamber on either side of the device in order to draw fluid from each chamber instead of a constant source.
What type of oil do I recommend for my vane pump?
The vane pump is not a motor, so any type of engine oil can go on it. It uses the piston and hydraulic fluid for suction, so any type of hydraulic oil such as Redline Diester can go on the vane pump.
What is the difference between hydraulic and mechanical pumps?
A hydraulic pump has a spinning impeller that turns inside of a container filled with liquid. The liquid falling from the rotating turbine is then converted into pressure and moves the other end of the container to lift the liquid. In contrast, in mechanical pumps the liquid enters through a valve into another chamber before being lifted up.
