• Function

1.Generating Hydraulic Pressure: The piston pump operates based on the reciprocating motion of pistons. Driven by an external power source such as an electric motor or an engine, the pistons move back and forth within the cylinder block. When the piston moves in one direction, it creates a low - pressure area in the pump cylinder, and fluid is drawn into the cylinder through the inlet valve. When the piston moves in the opposite direction, it compresses the fluid, increasing the pressure and forcing it out through the outlet valve. This process generates hydraulic pressure, providing the power source for the hydraulic system.

2.Ensuring Smooth and Stable Fluid Flow: The 288 - 6857 piston pump is designed to ensure a smooth and continuous fluid flow with minimal pulsations. This is crucial for the stable operation of hydraulic equipment. For example, in construction machinery such as excavators, a stable fluid flow can ensure the smooth movement of components such as the boom and bucket, improving operation accuracy and efficiency.
