caterpillar excavator hydraulic pump

Our hydraulic pumps are designed, built, and tested to withstand the harshest environments and conditions. We offer a comprehensive range of hydraulic pumps, motors, and related products. We also offer hydraulic pump maintenance by people with extensive field experience.

The CAT374D main pump is a heavy-duty centrifugal pump that works well in cooling tower water applications. This oil-free, single-stage submersible centrifugal pump does not require an external filter. The rotor, bearings, and seals are all wear-resistant and last longer. The CAT374D is ideal for chemical processing equipment, cooling towers, and heat exchangers in the industrial sector.

Many heavy construction machines, such as excavators, motor graders, and bulldozers, have hydraulic pumps as part of their hydraulic systems. These pumps are designed to pump high-pressure hydraulic oil (oil) and are controlled by the hydraulic motor control unit, which determines how much oil is pumped through the system. The CAT374D control valve is a two-position, two-way, four-way globe valve with a self-operated overflow function and high-performance hydraulic positioning. This valve is intended for use in excavator hydraulic systems. The product also aids in lowering system power consumption and increasing system efficiency.
