Hydraulic Pump Types and Applications

Different hydraulic systems require different pump designs. Before selecting a replacement, identify the original pump type and its configuration.

Hydraulic Gear Pumps

Hydraulic gear pumps are commonly used in tractors, agricultural machinery, construction equipment, and industrial hydraulic systems. Depending on the application, they may support steering, auxiliary hydraulic functions, or other machine operations.

Check the pump's displacement, rotation direction, shaft configuration, mounting interface, and port arrangement before ordering.

Hydraulic Piston Pumps

Hydraulic piston pumps are used in many high-pressure hydraulic systems, including excavators and other heavy equipment. Depending on the machine, the pump may have variable-displacement controls, regulators, or additional pump sections.

Replacement selection requires careful verification of the original pump model, configuration, and associated controls.

Tandem and Multi-Section Hydraulic Pumps

Some hydraulic equipment uses tandem or multi-section pumps to supply different hydraulic circuits.

When replacing these assemblies, verify the number of pump sections, displacement, shaft connections, port locations, and applicable control components.

Hydraulic Pump Repair Parts and Rebuild Kits

FAB Heavy Parts also carries selected hydraulic pump repair components and rebuild kits.

Repair kits and individual components are not substitutes for complete hydraulic pump assemblies. Confirm exactly which parts are included before purchasing.

Hydraulic Pumps for Construction and Agricultural Equipment

Explore hydraulic pump products for applications involving:

• Excavators: Hydraulic pump assemblies and related components for compatible excavator hydraulic systems.

• Tractors: Replacement hydraulic pumps used in selected agricultural and utility tractor applications.

• Wheel Loaders: Pumps for compatible loader hydraulic systems.

• Backhoe Loaders: Hydraulic pumps and replacement components for appropriate backhoe configurations.

• Skid Steers and Compact Equipment: Hydraulic components for selected compact equipment applications.

• Industrial Machinery: Pumps for compatible industrial hydraulic power systems.

Equipment make and model are useful starting points, but they do not independently guarantee pump compatibility.

How to Choose the Correct Replacement Hydraulic Pump

Hydraulic pumps may look similar externally while having different internal configurations. Before ordering, compare the following information:

1. OEM and Replacement Part Numbers

Identify the original hydraulic pump part number and any verified replacement or superseded references. Pay attention to suffixes and revision codes.

2. Equipment Make, Model and Serial Number

Confirm the full equipment model and serial number. Machines within the same model series may use different hydraulic pump configurations.

3. Pump Type and Displacement

Determine whether the application requires a gear pump, piston pump, tandem pump, or another configuration. Check the specified displacement and operating requirements.

4. Shaft and Mounting Configuration

Compare the shaft or spline design, mounting flange, bolt-hole arrangement, and physical dimensions.

5. Hydraulic Port Arrangement

Verify the inlet and outlet port sizes, positions, and connection types.

6. Rotation and Control Configuration

Check the required rotation direction, regulator, controller, solenoid, and other configuration details where applicable.

7. Complete Pump or Repair Components

Confirm whether your repair requires a complete hydraulic pump, a specific pump section, or individual replacement parts.

Always use the equipment manufacturer's technical specifications and service information when verifying fitment.

When Should a Hydraulic Pump Be Replaced?

Symptoms such as slow hydraulic operation, unusual noise, overheating, reduced hydraulic performance, or excessive leakage may indicate a hydraulic system problem.

However, these symptoms do not always mean the pump has failed. Hydraulic valves, cylinders, motors, filters, oil condition, hoses, or other components may cause similar issues.

A qualified technician should diagnose the system before determining whether pump replacement is necessary.

Find Hydraulic Pumps by Part Number or Equipment Model

FAB Heavy Parts offers hydraulic pump products for a range of construction, agricultural, and industrial equipment.

If you're unsure which hydraulic pump fits your machine, provide our parts team with:

• Equipment manufacturer, model, and serial number
