Cat® Hydraulic Piston Pumps, Hydraulic Gear Pumps, Hydraulic Motors, and components are designed, manufactured, and tested to meet the unique performance requirements of Caterpillar equipment models they are used in. This ensures they achieve the specific machine performance, reliability, durability, operating costs, and productivity requirements.
Maximize Machine Uptime with genuine Cat hydraulic pump and motor parts, which are covered by Caterpillar's Limited Warranty and deliver fast response due to a rugged, heavy-duty design for exceptional performance and extra-long life in mobile construction applications.
Cat hydraulic pumps and motors show proven results in a variety of construction equipment, including hydraulic excavators, mobile hydraulic power units, wheel loaders, cranes and more... Where you source hydraulic repairs can have a big impact on your bottom line. While most independent shops want only to sell you parts and labor, your Cat Dealer has a different goal: helping you control costs and maximize machine uptime.
Advanced electronic controls let you switch dynamically among three distinct control modes: load sense, pressure control, and displacement/flow control - all while managing engine underspeed control.
The design and manufacturing of Cat Piston and Gear pumps and motors also allows for a variety of service and repair options.
How do I diagnose whether my hydraulic pump or motor needs parts or a full replacement?
Available hydraulic pump and motor replacement parts include shaft seals, O-ring kits, bearing assemblies, port plates, pistons and cylinder blocks (for piston pumps), gears and gear housings (for gear pumps), and complete service kits. These allow for the rebuild of both gear-type and piston-type units.
What are the most common serviceable parts in a hydraulic pump or motor?
Symptoms of pump failure include low system pressure, slow or weak implement movement, excessive heat in the hydraulic system, loud whining or knocking noises from the pump, and contaminated hydraulic fluid. Motor failure typically presents as reduced speed or torque, overheating, or shaft seal leaks.
What's the difference between a gear pump and a piston pump in terms of repairability?
Gear pumps are simpler, less expensive, and more tolerant of contamination. They are commonly used for lower-pressure auxiliary circuits. Piston pumps are more complex but provide higher efficiency, variable displacement, and better performance at high pressure. They are used in main hydraulic circuits on most Cat excavators and dozers.
