The HYDSTAR® Hydraulic Piston Pump is a positive displacement pump that moves and pressurizes fluid by using one or more reciprocating pistons. The pump consists of a cylinder and a piston that moves back and forth inside the cylinder. The piston has one or more O-rings on its periphery, which seal against the cylinder as the piston moves. The piston draws liquid into the cylinder and pushes it out under pressure as the volume in the cylinder gets progressively larger and then smaller as the piston reciprocates.

Attributes:
● Able to handle viscous media and media containing solid particles
● Manufactured to precise specifications and is durable and reliable

Applications:
The HYDSTAR® Hydraulic Piston Pump provides a constant flow of fluid and provides increased efficiency and performance and provides high efficiency, precise flow control, and the ability to handle a wide range of viscosities.
