Pumps and Motors for Sale
Pumps and Motors for SaleHydraulic pumps and motors are the heart of a machine’s power system. They perform opposite functions. A pump converts mechanical energy to create fluid flow and pressure, while the motor uses that pressurized hydraulic energy for work.
Using quality pumps and motors for your machine is key to ensuring equipment performance and efficiency. Thompson Machinery is your source for reliable, high-performance Cat® pumps and motors that keep operations running smoothly. With over 75 years in business, we have the experience, equipment and staff to meet all your heavy equipment needs.
Heavy Equipment Pumps to Power Your Fleet
Pumps generate force to power a vast range of equipment. They help move components like cylinders and motors, ensuring continuous fluid movement and pressure to keep the whole machine working. Cat hydraulic pumps are built as integral components of a complete high-performance system. They are designed to deliver the exact flow and pressure specification for your machine, providing optimal power, speed and control.
Our line of heavy equipment pumps for sale includes:
Gear Pumps
Hydraulic gear pumps use two meshing gears to move hydraulic fluid, creating a consistent flow for reliable performance. Caterpillar manufactures these pumps to be exceptionally robust, using special pressure-balanced wear plates that press against the sides of the gears. This means you get a tighter seal, ensuring the pump maintains its efficiency for longer.
Piston Pumps
Piston pumps provide the power and efficiency required for high-pressure applications. They operate using pistons moving within cylinders to pressurize fluid, providing smooth, efficient and reliable power. Cat piston pumps are variable displacement. This means they only produce the flow and pressure the machine demands, leading to improved energy efficiency, lower fuel consumption and less heat generated in the system.
Vane Pumps
Vane pumps are ideal for low-noise operations. Cat models have a cartridge design where the entire rotating group is contained in a single, replaceable unit. When the pump wears out, you can unbolt the housing and replace the cartridge in minutes. This enables lower repair costs and minimizes maintenance downtime.
High-Performance Motors for Your Fleet
Hydraulic motors convert the pressure generated by the pump into torque and rotation. They deliver reliable performance and enable precise control for your heavy equipment, including excavators, loaders and winches. Our heavy equipment motors for sale are engineered as part of a matched system to ensure compatibility with Cat pumps.
Our selection of Cat hydraulic motors includes:
- Gear motors: This type of motor is reliable and cost-effective, providing high speed for powering sweepers, conveyor belt drives or engine cooling fans.
- Piston motors: These motors provide high torque and precise control and are ideal for high-pressure applications like final drives, swing motors and attachments like grinders or large augers.
- Vane motors: This option produces smooth, ripple-free torque at high speeds to power attachments like grinders or polishers.
