2. Hydraulic Pump Gasket Function and Materials Overview

Hydraulic pump gaskets provide a critical seal between mating surfaces within the pump body to prevent hydraulic fluid from escaping under pressure. They are essential to system efficiency, fluid control, and leak prevention.

Hydraulic pump gaskets must withstand exposure to hydraulic fluid, maintain surface contact under stress, and perform reliably under long-term pressure and vibration.

Common material types include:

• Rubber-Coated Metal (RCM) – Offers excellent fluid compatibility and structural stability
• Foamet Rubber-Coated Metal – Adds micro-sealing ability for surfaces with minor imperfections
• Metal bonded with rubber – Ensures high sealing strength under mechanical load and pressure cycling
