Description
Description
Description: A Hydraulic Pump Piston is a component of a hydraulic pump that is responsible for generating fluid flow by moving back and forth inside a cylinder. The piston is typically made of high-strength material, such as steel, and is sealed against the cylinder walls by a set of hydraulic seals. When the piston is moved in one direction, it creates a vacuum that draws fluid into the cylinder. When the piston is moved in the opposite direction, it forces the fluid out of the cylinder and into the hydraulic system.
Attributes: • Resistant to corrosion. • Strong enough to withstand the operational forces. • Durable and can withstand the wear and tear caused by the constant movement of the piston.
Applications: A Hydraulic Pump Piston is used to generate force and control movement. It is used in Cat 320, 328D, 330, 330C, 330D, 336, 336D, 340D, 350, and 365 OEM Applications, 320C, 325C, 328D, 330C, 330D, 335F, 336, 336D, 336E, 336F, 340D, 340F, 345, 350, and 365B Excavators, 330C, and 330D Material Handler, 336E Base Machine-Cosg-336e Hvg, 336E - Base Machine-Cosg-336e L Uhd, 992H, 993, and 993K Wheel Loader, D3K, and D6K Track Type Tractor.
Warning:This product can expose you to chemicals including Lead and lead compounds, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
