What's a Excavator Hydraulic Piston Pump?

A hydraulic piston pump is a type of positive displacement pump that uses reciprocating pistons to move fluid. It is commonly used in hydraulic systems to generate high-pressure fluid flow. The pump works by drawing fluid into a cylinder through an inlet valve and then forcing it out through a discharge valve. The piston movement creates a vacuum that draws in the fluid and then pressurizes it as it is forced out. Hydraulic piston pumps are known for their high efficiency, reliability, and ability to handle high-pressure applications.

Texcavator hydraulic pump working principle:

The excavator hydraulic pump works by converting mechanical power into hydraulic energy. The pump draws in hydraulic fluid and then pressurizes it, which creates flow. This flow is then used to power the various hydraulic systems on the excavator, such as the boom, arm, and bucket. The hydraulic pump is typically driven by the engine of the excavator and can be either a gear pump or a piston pump.
