It is important to invest in a hydraulic pump for dump trailers. These devices help drain oil or other liquids rapidly and with accuracy. This guide provides tips and advice on how to buy a hydraulic pump for a dump trailer.
what size hydraulic pump do i need for a dump trailer?
To determine your hydraulic pump’s size, begin by figuring out your trailer’s weight. This is the foremost factor to consider in deciding which type and size of hydraulic system you needs.
If you have a dump trailer that is less than 5 tonnes, it might be possible for you to get away with using a smaller hydraulic pump. However if your trailer weights more than five tons and/or carries many other trailers at once, you will need a bigger sized pump.
Moreover, check how many people are presently operating on the trailer (example; multiple operators). Additionally, if there are various workers who are often required to access such machine simultaneously, then this will also affect the whole thing concerning its dimension.
Dump trailer weight
What size hydraulic pump should I get for a dump trailer?
Dump trailers come in various sizes, from small, two-wheeled ones weighing up to 1,000 pounds to large four-wheeled ones having a carrying capacity of 10,000 pounds. Usually, dump trailers take dirt and materials on site. In case you have a big-sized dump trailer that frequently carries heavy loads, it is essential to know the right size of hydraulic pump to buy.
The size of the hydraulic pump will therefore depend on the weight it has to move. To know how much your hydraulic pump needs to move multiply the weight of your load by its distance from your axle centerline. For instance let say you are having a load with a weight of 15000lb which is located at 10ft away from your axle centerline then you would multiply 15×10=150 (in pounds) and then divide by 12 (the number of inches per foot) which equals 12.5 inches per pound or 150/12=12.5. This means that your hydraulic pump needs to be able to move 12 inches per pound or more (12″/150#=0.080″).
Dump trailer hydraulic system
Closed loop
Dump trailer hydraulic systems are generally classified into two types, namely closed and open-loop. However, although the most common type of hydraulic system on dump trailers is closed-loop, there are still some that use open-loop systems.
On dump trailers, the closed-loop hydraulic system is the most commonly used type of hydraulic system. It most often includes a pump, tank, filter, valves and lines interconnecting these components together. Closed loop design offers more accurate control and better efficiency than its counterparts in terms of packaging.
Fuel costs need to be minimized since this leads to efficiency. All components in a closed loop work together thus making it easier to control the dumping process.
Open loop
An open-loop system does not have a pump or tank; rather, fluid flows through it due to gravity alone. This makes them less efficient than their counterpart: gravity takes longer when moving fluid through an open system than it does through a closed one for instance.
Factors affecting the size selection of dump trailer hydraulic pump
With the need of choosing one, more and more customers are now looking at factors that affect the size selection of dump trailer hydraulic pump. To make things worse, every detail about this product is found on the internet as because each time making a purchase becomes an actual struggle with oneself. In order to facilitate your choice, let me tell you several factors about truck trailer hydraulic pump.
Capacity
The weight of the payload on a dump trailer usually accounts for about 10% of the total mass. For instance, if a dump trailer weighs 10 tons, it can carry either 1 or 2 tons of load. However, if it has been loaded with 2 tones and cannot lift to over 20 meters, then its capacity has been attained.
Also, the design of hydraulic pump must be included in its power calculation. If for example you wish to increase your vehicle’s lifting height by five meters, you need to acquire a greater hydraulic pump; otherwise, it will not work correctly.
Weight
The dump trailer weight is among the most vital features which determine the performance of hydraulic pumps. In case your dump trailer contains heavy loads, the oil will contain a lot of air bubbles and this will hinder movement by the pump. In order to avert this situation coming up, you should keep on cleaning your oil regularly. Otherwise you may add some disinfectants in it so as to keep it clean and flowing smoothly.
Pressure
The hydraulic pressure of a dump trailer is usually higher than the normal hydraulic system. When the filter becomes blocked, it will not operate normally or may even fail completely. So when we have to change the filter, we have to check whether there are any damaged hoses which leak before replacing. Once we are sure that all other parts are not problematic; then we can replace it.

The type of motor: AC or DC
The dump trailer hydraulic pump is a motor type. The first kind is AC motor which can be used for the dump trailer hydraulic pump. The second one is DC motor that can also be used for the dump trailer hydraulic pump.
An alternating current source generates an electric field as electromagnetic forces attracting or repelling an armature (a rotating spindle wrapped in coils). This armature moves gears, which then move other sections of the dump trailer hydraulic pump.
On the other hand, DC motor sources direct current that produces an electric field through electromagnetic forces’ attraction and repulsion on an armature (spinning spindle with wrapped coils). The armature moves gears; these in turn rotate some parts of the dump’s hydraulic system.
The voltage: single or three-phase
Hydraulic pumps in dump trailers are usually powered by a 12V or 24V DC. Some can be run on either a 12V or 24V supply while others rely upon one voltage only, choosing which voltage is all about personal preferences as well as the type of dump trailer that you have.
In case you decide to operate your dump truck within an area having many hills and mountainsides then it is better to choose a three-phase system to boost power. That’s because unlike single phase systems that use just one wire, three-phase systems employ three separate wires. Therefore at any given time there will be more current available meaning that the hydraulic pump will produce more torque.
Moreover if you intend to put very heavy loads on the bed of the truck such as boulders or other stuffs then it would also be good to choose a three-phase system so that the bearings don’t burn out prematurely due to overloading of the motor. If you still want enough power from your hydraulic pump but also wish to save cash, two pumps instead of one should suffice. Although not capable of providing as much torque as one pump can manage, this second pump can nonetheless lift most loads.
The connection type: shafted or flanged
Hydraulic dump trailers use hydraulic pumps to lower and raise the dump bed. There are two kinds of hydraulic pumps: shafted and flanged.
Shafted Pumps
These types of hydraulic pump is best suited for smaller, lighter trailers that have shorter cycles because it is mounted on the trailer frame or undercarriage, where a shaft runs along the length of the trailer connecting it to a hydraulic system. To access them, parts of the trailer require disassembly which makes them harder to maintain compared to flanged pumps.
Flanged Pumps
These can be either mounted on top of or underneath your trailer; however, most are mounted on top and connect directly with a flange welded onto the dump bed. It will cost you more money than its shafted alternative though less servicing is required for this type of hydraulic pump since in addition to your already installed dump bed plate you would need another flange plate for it (which may already have been fitted).
The port size: SAE or NPT
One of the most frequently asked questions about dump trailer hydraulic pump is its port size. The straightforward response is: it does not matter. However, the lengthy response is that it depends on the application and if you want to run at higher pressures or not.
The dump trailer hydraulic pump port size is typically referred to as either SAE or NPT. But if you don’t know what these mean, don’t be sorry about it. The only thing you should know is that they refer to the type of threads in connection between your trailer and your hydraulic pump. There are two main types of thread sizes: SAE (Standard Automotive Equipment) and NPT (National Pipe Thread). Each has its own advantages and disadvantages; however, for most applications either one will work fine.
SAE Threads
SAE threads are very popular since they were standardized in 1919 by the American Society of Mechanical Engineers (ASME). They have been used virtually everywhere on cars, trucks and various other vehicles because they’re simple to manufacture, cheap, easy to fix/repair and available in many different sizes and lengths.
NPT Threads
In 1968, ASME standardized NPT threads after there were pressure problems with using SAE threads at high pressures required by many industrial and commercial applications. Plumbing systems use NPT threads as well as HVAC systems, water heaters, among others around the house.
The material: aluminum or cast iron
One very important consideration to take note of is the material of the hydraulic pump for dump trailer. Poor materials used in making these pumps reduce their efficiency and can cause accidents. Some of the factors that should be considered when selecting a material for the hydraulic pump are listed below:
Materials made from aluminum alloy
These materials have good performance and are relatively cheaper. However, they corrode easily and require more maintenance compared to cast iron materials; hence not advisable if you don’t want to spend on maintenance.
Materials made from cast iron
They cost more but last longer than aluminum alloys. To ensure that your dump trailer has lesser or no frequent maintenance costs, cast iron is an excellent choice.
Manufacturers of dump trailers use the above two materials as they suit the requirements differently. In case you want to buy such a trailer; then those two mentioned before can be taken as good examples.
hydraulic pump for dump trailer FAQ
how to install pressure gauge in 12 volt hydraulic pump for dump trailer?
1. Turn off your dump trailer and make sure it is in park.
2. Find the mounting bolt on top of the pump that holds the top cover on. The mounting bolt will have a nut on it that you can use an open end wrench to remove. After removing this nut, you will be able to lift off the top cover of your hydraulic pump.
3. Inside of the hydraulic pump there will be several wires connected to different parts of the pump. Disconnect these wires by pulling them out with needle nose pliers or some other type of tool that can grip small objects tightly without damaging them. Make sure you remember where each wire was connected so that when it is time to put everything back together again you don’t connect them incorrectly!
4. Once all of the wires are disconnected from their respective parts inside of your hydraulic pump, take out all of the parts with needle nose pliers or some other type of tool that can grip small objects tightly without damaging them. It may be easier if you remove all of these parts before disconnecting any wires so that when you put everything back together again there is no risk of mixing up the parts.
5. Once all of your parts are removed from the pump, take a look at them and make sure they are clean. If there is any dirt or grime on them you need to clean it off with some warm water and soap before putting everything back together again!
okay i want to see how it wiring electric hydraulic pump for dump trailer?
You can use the following steps to wire your dump trailer:
1. Connect the positive wire from the battery to the “B+” terminal of the controller.
2. Connect a wire from the “B-” terminal of the controller to ground (for example, a bolt that you’ve screwed into a metal surface).
3. Connect a wire from terminal “A+” on the controller to terminal “A-” on the pump.
4. Connect another wire from terminal “A+” on the controller to terminal “B+” on one valve and then connect another wire from terminal “B-” on that same valve back to ground again (so you’re creating an electrical loop).
5. Repeat step 4 for each valve except for the last one — connect terminal “A-” on that valve back to ground instead of connecting it directly back to terminal “B-” on its own controller like you did with all other valves, otherwise it won’t work correctly!
how much flow for 12v hydraulic pump on dump trailer?
Most dump trailers use diesel engines to power their hydraulic pumps. The size of these engines depends on how much weight your dump trailer can handle and how much fluid it needs to move around. Smaller dump trailers might only require a 3-5 horsepower engine, while larger ones may need up to 15 horsepower motors.
There are two main types of hydraulic pumps: gear pumps and vane pumps (also known as piston pumps). Both types work by using pistons to compress air inside cylinders, which creates pressure that pushes against oil in the lines and moves it across your system. Vane pumps are generally more efficient because they don’t use gears and mechanical parts like gear pumps do; however, they’re also more expensive than gear pumps so if you don’t have a lot of money to spend on your trucking business then gear pumps might be better for you.
hydraulic pump for dump trailer what different btwn single acting and double acting?
The hydraulic pump for dump trailer is the heart of the dumping system. It drives the piston to make up and down movement. The hydraulic pump for dump trailer can be divided into single acting and double acting according to its working principle.
Single Acting Hydraulic Pump for Dump Trailer
In single acting mode, the piston only moves in one direction, in order to make an impact on the parking brake release valve. With this kind of hydraulic pump for dump trailer, you need to control it manually or it will be damaged by overload.
Double Acting Hydraulic Pump for Dump Trailer
In double-acting mode, two pistons are used to drive the piston rod in each direction. When one piston is driven by fluid pressure, another one takes over its position immediately and performs another action at the same time. This kind of hydraulic pump for dump trailer will not be damaged because it has a built-in overload protection device that automatically shuts off if there is too much pressure on its actuator valves or pistons.
i want to find out what type of hydraulic fluid at electric pump used for dump trailer
The hydraulic fluid used in dump trailers is called “hydraulic oil.” It is a non-toxic, synthetic oil that contains detergents and other additives to help prevent foaming and corrosion. The oil can be a viscosity grade of SAE 30 or 10W-30.
If you want to use a different type of hydraulic fluid, then you need to check with the manufacturer of your trailer or tractor to make sure it meets their specifications.
The standard color of most hydraulic fluids is yellow or amber. You should avoid using green or blue colored fluids as they may be contaminated by water or have been overheated.
