Hydraulic pumps are a crucial component in most machinery found in industries such as construction, manufacturing, agriculture, and transportation. Hydraulic Pumps assist in the movement of fluid under pressure to drive equipment and tools. However, just like any machine component hydraulic pumps fail as time goes by because of wear and tear. Learning how to repair a hydraulic pump can save you money and time. In this easy-to-use guide we describe the kinds of pumps failure reasons and step-by-step solutions for simple repairs.
What are the Various Kinds of Hydraulic Pumps?
Before repairing a hydraulic pump one should know about the kind of pump you’re working with. The most used types of hydraulic pumps are:
1. Gear Pump
This is one of the most basic hydraulic pumps. Two moving gears rotate to pump fluid. These pumps are long-lasting simple to maintain and utilized generally in low to medium-pressure systems.
2. Vane Pump
A vane pump incorporates vanes installed in a spinning drum. When the drum is in motion, the vanes push fluid within the system. Vane pumps offer smooth and quiet operation and are applied to medium-pressure purposes.
3. Piston Pump
Piston pumps are high-power and utilized in high-pressure systems. Piston pumps utilize pistons powered by a rotating shaft to pump fluid. Piston pumps are more complicated and typically used in heavy equipment.
All pumps have varying components and repair procedures so you must determine the type prior to commencing the repair procedure.
How to Repair Your Hydraulic Pump
When you see low pressure loud sound or leaks repair time may have arrived for your hydraulic pump. For a simple repair follow these steps:
Step 1: Turn Off the Machine
Before any repair work is initiated ensure that the machine is shut down and the hydraulic pressure is released fully to prevent accidents.
Step 2: Disconnect the Pump
Disconnect the pump from the machine. Mark the hoses or take pictures to assist in reconnection later in the correct sequence.
Step 3: Clean the Pump
Clean the outside surface of the pump to avoid introducing dirt into it. Carefully open the pump and examine the inner components.
Step 4: Check for Damage
Check for worn vanes, damaged seals, broken gears, or piston wear. Check the casing for any cracks. Document parts that are to be replaced.
Step 5: Replace Defective Parts
Replace the defective parts using new quality parts. Always employ proper tools and adhere to the pump manufacturer’s instructions.
Step 6: Replace Seals and Filters
Even if the seals appear to be fine it is best to change them with every major repair. Check and also replace oil filters to maintain cleanliness in the system.
Step 7: Assemble the Pump
Assemble the pump together and ensure each bolt and connection is tightened tightly. Fill the system with fresh oil and clear any trapped air.
Step 8: Test the System
After you have installed the pump back into the machine slowly turn it on and observe for any leaks. Verify if the pressure returns to its normal level and listen for any strange noises.

Why Do Hydraulic Pumps Fail?
Hydraulic pumps can fail due to various reasons. Knowing the reason for failure prevents it from occurring again. Some of the common reasons are:
1. Contaminated Hydraulic Fluid
Dirt water or other contaminants in the fluid can ruin the pump’s internal components. Always utilize clean recommended fluid.
2. Overheating
Hydraulic systems generate heat while working. When there is inadequate cooling or the pump operates continuously without a break it overheats and wears out earlier.
3. Damage to Seal and O-Ring
Seals and o-rings prevent leaks in a hydraulic pump. When these parts wear out fluid leaks occur and pressure drops which affects performance.
4. Cavitation
Cavitation is an occurrence where air penetrates the hydraulic fluid. This forms bubbles which implode within the pump and wreck its components over time.
5. Low Maintenance
Avoiding routine checkups not changing filters and getting the wrong oil are some of the main causes pumps fail before they should.
