Pressure Gauge
Hydraulic piston pumps are one of the most widely used types of pumps today. These are dependable and productive machines that can be found in various applications. Nevertheless, there is a whole host of challenges associated with them. In this article, we aim at highlighting some of the typical hydraulic piston pump troubleshooting problems. We will also share some guidance on how to fix these problems.
Relief Valve / Regulator Issue
Should you experience problems with hydraulic piston pumps, there is a need to investigate into the problem. In this context, we will assess whether the defect is related to relief valve or regulator failure. Relief valves are devices designed to release pressure from a hydraulic system in an emergency situation. If your relief valve works improperly, you may get a breakdown of the pump. The role of a regulator is to regulate pressure in the hydraulic system within certain limits. It can also cause failure of a pump if it malfunctions. To troubleshoot your hydraulic piston pump you should:
1.Check for proper operation of the relief valve .If this valve fails to open or close properly, it could be defective and require replacement.
2.Examine the regulator’s operation levels on pressure; if they are not regulating correctly then it is likely that they might be damaged and therefore need replacing.
3.Check if any leaks or damages appear on hoses and connections between relief valve, pressure regulator as well as pump assembly; henceforth fixing them immediately would inhibit further damage to this assembly.
Seats or Valves Worn
In various industries and commercial premises, hydraulic piston pumps are a common form of pump. These are often used in transporting liquid in any irrigation system or water tank. Hydraulic piston pumps can cause many problems when incorrectly used.
One of the major problems with hydraulic piston pumps is that they can get overloaded provided the seats or valves which control the flow of liquid become worn out or faulty. In such cases, failure will be imminent due to the increased pressure exerted on it by the pump. At times, this may tear apart the housing casing of the pump or even result into explosion.
When your hydraulic piston pump goes wrong you must not hesitate to take action. Look for ways through which you can inspect any sign of damage on this equipment but when there is damage then replacing it might be necessary. Otherwise, one may fix it using certain tools/technics. If unsure about how to repair a damaged pump, always feel free to hire an experienced technician who works in this field.
Suction Filter Clogged
When a suction filter is obstructed, the pump might be unable to discharge water or gases from it. Replace the filter every six months or when it becomes evidently blocked. In case you are confident that your pump is in perfect condition but it is not working at all, you will have to replace it. Getting a new pump is easier than changing a water softener.
Insufficient NPSH Available
The problem of the hydraulic piston pump should be troubleshot immediately. These are some common problems experienced with a hydraulic piston pump and how to fix them:
1.To check NPSH of the pump, adjust an adjusting screw until the necessary pressure is reached. However, it should be noted that the adjusting screw cannot be adjusted until the required NPSH has been achieved.
2.In case NPSH hasn’t attain the desired pressure, then you may need to change oil seal or check for blockage in discharge line.
3.If none of these steps work, chances are high you may have to replace your hydraulic piston pump.

Leakage
One of the most frequently encountered mechanical failures is hydraulic piston pump leakage. Understanding how a hydraulic system works is crucial to diagnosing and fixing leaks in hydraulic piston pumps.
When activated, pressurized fluid is forced through narrow channels in the hydraulic system (piston) and out of the another side. Such pressurized fluids are used to move things like boats when they are on water.
The most common type of leak found in a hydraulic system occurs when seals protecting these pistons against any leakage breakdown. This causes pressurized fluid to come out thus damaging different parts of this system.
To avoid a leakage, it’s vital that an individual completely grasp the functioning mechanism of the hydraulic system and some possible drawbacks. When you detect any signs of such leakage, get assistance from a mechanic who will establish its cause as well as fix the problem.
Noisy Pump
Hydraulic piston pumps are among the most commonly used pump types in industrial and commercial applications. Frequently, these pumps are employed to circulate fluids through a system, which can generate a lot of noise. Sometimes it is difficult to identify what makes noisy hydraulic piston pumps? In this blog post, I will discuss some of the common causes of noisy hydraulic piston pumps that you may need to troubleshoot.
It’s likely that your pump has something wrong with it if it makes a lot of noise. In cases where a pump starts making too much noise, this is often an indication that there is something wrong with one or more parts inside the pump. The following are some of the common causes of loud hydraulic piston pumps:
Knocking Sound: There is a good chance your hydraulic piston pump is knocking or banging away if you hear such noises. This article discusses the main reasons why your hydraulic piston might be knocking and provides assistance on how to fix them.
Suction Sound: If you detect any strange sound in your hydraulic piston pump, then maybe its time for troubleshooting tips. Some steps to begin with include:
1.Checking for blockages in the intake and exhaust ports of the pump caused by debris.It can also make the impeller rotate constantly thus making sounds.
2.Ensuring that seals are properly fitted on the pump and they are in their rightful position.Otherwise water will get into this machine hence leading to sound production as well.
3.Verify that motor power requirement corresponds with its RPM values.The reason as to why motor does not turn or become weak could necessitate fixing it.
4.If all those tests do not solve this noise problem,take out her parts and scrutinize them for damages or wear and tear.
Screeching Sound: When you switch your fountain on and hear screeching sounds then check on bearings first. Ensure if there’s no gap between wellbore casing point and top platter around which seal exists. In case the well is dry, add water to it and try again. However, if screeching persists there could be motor or transmission issues.
Worn Crankcase Oil Seals
Problems can be encountered with the cyclical piston pump due to damaged crankshaft oil seals. These cases may hinder the pump’s ability to generate enough pressure for fluid movement purposes. This then leads to decrease in efficiency and potential damage to equipment.
In order for one to troubleshoot and diagnose problems related with hydraulic piston pumps, it is crucial that the source of problem be identified. The engine block should therefore be checked for wear or other forms of damages. Another thing that may need to happen is testing the performance of a pump using a pressure gauge.
If this seems related to a worn crankcase oil seal, then there are some available choices in repairing or replacing it. An OEM part could sometimes be fabricated into a replacement seal. Alternatively, certain seals can be replaced with rubber or silicone that is more resistant than others.
When faced with most hydraulic piston pump problems, it would be wise if one contacted a manufacturer or professional who will help him/her get over it faster without much waste of time and resources.
Bearing Wear
In case you have bearing wear on your hydraulic piston pump, there are several steps you can take to troubleshoot and fix the problem. Here is what to do in order to establish the root cause of bearing wear:
1.Calculate the force required for moving the pump. Any increase in thrust force may imply a problem with bearings.
2.Examine seals near bearings for any signs of wear or leakage. When worn out or leaking, such will bring down thrust force hence indicating the necessity of substituting bearings.
3.Check if any foreign bodies or debris are causing friction between the bearings. In order to make your pump operate normally without any further incidence of wearing off its bearings, it is necessary that one should clean their seals and remove trash from them.
Plunger or Piston Wear
Hydraulic piston pumps are frequently affected by piston or plunger wear. In turn, this can lead to premature pump failure thus reducing flow rates and increasing pumping costs. Here are some tips for diagnosing and repairing plunger or piston wear:
1.If the pump produces lower flow rates, it indicates that the wear is located on the plunger. You may determine this by measuring the flow rate using a syringe before and after running the pump at full capacity for several minutes. If the flow rate drops after using the pump at full capacity, then most likely there is wearing off of the plunger.
2.If you have a pump that does not run up to its maximum ability, then it means that there is wearing off of pistons’ sleeves. To find out if these symptoms are indeed due to worn pistons, put a drop of oil into a one of the pump chambers. And if artificial friction arises from such action, I must deduce that one of my pistons is already worn!
3. If both tests fail, then you could suspect an intermediate location between pistons and plungers as responsible for any wear. In such a case, you will have to take apart the pump so as to identify where in between these two parts occurs this effect.

Drain Plug / Oil Gauge Leaking
Whether you hear a roar, a grinding sound, or simply smell something foul, find out about some tell-tale signs that indicate your hydraulic piston pump is in trouble. In this post, we’ll talk about some common issues with hydraulic piston pumps and how to troubleshoot them. First, let’s see what can be the reason for a drain plug leaking.
There is a rubber seal known as the drain plug which prevents oil from seeping out of the cylinder while it works. If the seal is bad however and oil finds its way out then your pump will fail too. Different causes lead to different kinds of leakages in drain plug. Here are few tips on how one can identify and mend a leaking drain plug:
1.Check engine oil level: low engine oil level might mean it’s leaking off through the cylinder so check out the level to ensure there is enough oil .For this reason alone replace any other drained amounts as well as make sure you use a new drain plug!
2.Look for burned or warped pistons: Warped pistons may result into leakage of oil due to their irregularity when fitting inside cylinder Replace these pistons in such situations.
3.Look for Missing Dampers: Also, unfastened dampers or even absent ones could generate a loose drainage plug. Should you find one on replacement make sure it does not move around this time.
Insufficient NPSH Available
Usually, hydraulic piston pumps are items that are seen in industrial applications; they can be used for moving liquids, gases, or powders. They rely on the principles of fluid dynamics and use a rotating cylinder to compress a fluid. When the pressure in the cylinder reaches a certain point, an opening at the top of it will let the fluid get out.
The pump head, piston and cylinder are the main components of hydraulic piston pump. The pump head is what comes into contact with fluids. It has valves that allow compressed air or liquid to enter or leave it. Inside of the cylindrical tank is where you find pistons which are connected to the pump head by means of lifter rod. As soon as pressure inside the cylinder exceeds certain value, it makes a lifter rod extend and allows pressurized fluid escape from the pump head.
There might be several causes making performance of hydraulic piston pumps go down or even fail them altogether. Some common examples include insufficient NPSH available; cavitation; fouling and wrong lubrication methods used. Understanding each issue’s impact on overall performance is important before conducting any troubleshooting process for these problems
Inlet or Discharge Valves worn / sticking
To begin with, you need to identify the issue that is affecting your hydraulic piston pump. The valves also, over a period of time, tend to wear out and become stuck open or closed. When this happens, the pump stops working at all. In case any problems occur, there are some things you can do to fix them and get your machine up and running.
1.First, confirm whether they are dirty or corroded by checking the valves for dirt or corrosion. Also check the seals and O-rings that protect each valve if everything looks good. Replace any damaged or worn parts when necessary.
2.Ensure all hoses as well as lines which attach the valves with pump are properly linked. One line may be leaking making the valve not to move hence sticking on it. Check for any broken or twisted lines replacing where necessary.
3.For testting purposes insert a small rod less than one inch in diameter into each valve in turn and turning it clockwise should help you troubleshoot whether one of them is gritted up or jammed down by debris in its body cavity.
Discharge Pipework
Hydraulic piston pump is one amongst the most common types of pumps used in various industries and commercial fields. They are utilized in the movement of fluids such as water, oil or gas. Incorrect operation of a hydraulic piston pump can cause issues with discharge piping.
In case you have trouble with your piston pump, there are several things that you may try to do for troubleshooting purposes. First, ensure the pump has been properly installed and it is working well as per the manufacturer’s documentation. If you still have any issues then try isolating the issue as per below:
1.Clogs in discharge piping – use camera or make an inspection using other appropriate device to identify objects blocking fluid flow.
2.Unblock the discharge pipe using a plumbing snake or plunger.
3.Restarting by removing and replacing parts of assembly.
4.Check for any damage to the pump housing or its components; if any damage is evident then a complete replacement might be necessary for this whole pump assembly.
Scored Plungers
In hydraulic axial piston pumps, the plunger moves up and down inside a cylinder that is filled with pressurized fluid. This movement induces a flow of liquid that is utilized for machinery operation or object motion. When the plungers do not move in this manner, it can cause problems for the pump.
Here are some steps to take when troubleshooting a hydraulic axial piston pump if it is not functioning properly. First of all, you want to ensure that you have installed right components. Ascertain that the fluid level is correct and all seals are working properly. If these things are okay then you might consider replacing pistons or cylinders as an option. Should this be futile you might have to replace your pump as well
Scored Cylinders or Sleeves
For those who work with such kinds of pumps, trouble shooting of hydraulic piston pump is fairly common. It is always hard to find out why something has gone wrong. In this blog post we will look at some typical problems associated with hydraulic piston pump and how to correct them.
Hydraulic piston pumps are commonly used across many industries for purposes of fluid/gas motion. They can however sometimes have troubles because they are dependable devices. In this blog post, we’ll tackle some common issues involved in hydraulic piston pump troubleshooting and ways of solving them.
Inlet pressure too High
Damage to the pump and/or equipment will occur if there is too much inlet pressure on a hydraulic piston pump. Some things that might cause an excessive inlet pressure are either a bad pressure regulator or clogged pressure control valve. The simplest method of dealing with this situation is replacing the pressure regulator in case it results from a faulty pressure regulator. Removing and cleaning the valve would be best if it were caused by a clogged pressure control valve.
High Fluid Temperature
The transportation of fluids within industrial, agricultural and construction applications requires hydraulic piston pumps. These pumps rely on hydraulic oil to make a seal between the piston and cylinder. The pump will not work well if the oil is too hot or too cold.
High temperatures in the system lead to breakage of oil seals as well as more wear on the pump components. Consequently, this can cause the pump to fail hence injuring or killing someone when it happens.
Low temperatures also affect pumps negatively. Besides being thick and sticky, cold oil may lead to slow movement of fluid through a given pump because of resistance that results from its viscosity. In addition, low temperature levels may freeze oil seals thus causing further damage.
If you detect any change in your hydraulic piston pump’s performance level, then check first for excess fluid in the system which might be an indication of high or low oil temperature else other mechanical complications such as worn-out seals.
Worn Seals or V Packings
Worn-out seals or V packings may not allow a hydraulic piston pump to work properly. One possible reason for this is the accumulation of dirt on the seals or V packings. Hence, cleaning of the seals and V packings is necessary for restoring full functionality of the pump. To do this, detach it from the system and fix another set of sealing elements.
Lubrication issues. Wherein proper pressure fails to make this seal seal, it can cause other internal parts wear out too soon affecting life span. A vacuum gauge can help to detect problems related to leakage in sealing. Whether there are signs of leaks or not, it is recommended that one should replace these components with new ones: either seals or V packing thus allowing them to maintain optimum conditions all round (Paragraph 6). Generally speaking they should be replaced when one has failed but still been successfully tested whereas another one has not leaked yet during an initial flush test (See Replacing Seals).
Worn Adaptor
Most bloggers find it challenging to link their hydraulic piston pump with the power source. Typically, this is due to a damaged or worn-out adaptor. Some common causes of hydraulic piston pump troubleshooting and how it can be fixed are discussed here below:
1.The adapter gets old/worn out.
2.The coupling has not been tightened adequately.
3. The adapter does not match the Hydraulic Piston Pump
Damaged Plunger
Water treatment industry is a place where hydraulic piston pumps find most of their use. They are reliable and energy efficient, but can also have some issues. In this article, we will examine some common problems with hydraulic piston pumps and how to fix them.
If your hydraulic piston pump isn’t pumping water as it should, there are a few things you can do to try and diagnose the problem. First, check that all hoses and connections are tight. Next off is checking the pressure gauge to see if the pump is operating at the correct pressure. Lastly, you may want to look at the plunger assembly to see if there’s anything wrong with it or if it is damaged in any way.
If pressure gauge reads correctly but the pump does not move water, it may be because the plunger assembly has been broken. To replace the plunger assembly follow these steps:
- Disconnect power supply from pump by withdrawing plug at back of unit; make sure you do not pinch any wires during this process!
- Unscrew four screws that hold plunging arm down on top of motor housing; lift out arm and discard it once unscrewed.
- Remove five screws holding plunger assembly down. Once released pull out whole unit.
- Take off two screws holding down pump support plate then remove plate.
- Detach wiring harness from motor and board (black wires on white connector).
- Unfasten nut holding end of plunger in position
- Put aside all parts and clean dirt etc under them before reassembling them backwards
Manifold Wear / Damage
