Cat hydraulic pump features vary by model.
Gear Pumps
Used in open-center applications that require increased pressure and temperature capabilities, Cat gear pumps are optimized with rugged journal bearings, high-pressure end plates and high-temperature seals that extend component life.
Features:
- Simplest, most rugged and least expensive
- Highest resistance to contamination
- Well suited to lower-pressure, higher-flow applications
- Lower pressure capabilities
- More durable and reliable two-piece cast iron vs. three-piece aluminum design helps prevent shaft seal leaks that may result from impact
- Smaller units use valves to improve hydraulic system integration
- Available in fixed displacement
Vane Pumps
Used in open-center applications, Cat vane pumps feature a refined design of the cam-rings, pressure plates and pressure seals to withstand tougher duty cycle requirements, including increased pressure limits.
Features:
- Relatively simple and inexpensive
- Used in less-demanding applications
- Available in fixed displacement
Piston Pumps
Highly refined to satisfy the demand for increased hydraulic system efficiency, longer service life and improved overall value, every Cat pump model is customized to optimize performance and life for its intended application.
Features:
- Most efficient
- Highest pressure capabilities
- Less resistance to contamination
- Slightly higher cost
- Available in fixed or variable displacement

The Choice Is Yours
Regardless of the utilization or age of your Cat machine, when hydraulic components need servicing, your dealer is a one-stop shop for selection and service. Dealers offer a comprehensive lineup of on-demand repair options to fit your budget and time requirements.
Select from the most basic and economical maintenance and repairs, such as a pump rebearing and reseal, to full component replacement with remanufactured
(Cat Reman) or brand-new Cat parts.
Durable new and Cat Reman replacement parts extend life and minimize contamination/collateral damage to your hydraulic system.
Strict adherence to reuse and salvage guidelines assures peace of mind with repaired parts performance.
Convenient availability and common parts between sizes/series reduce operating cost and promote faster turnaround.
