What Are Piston Vacuum Pumps?

Piston pumps are a type of positive displacement vacuum pump that utilizes reciprocating pistons to move gases through the pumping chamber. As the piston moves back and forth, it creates a vacuum that draws gases into the pump and compresses them for discharge.

This proven technology has been used for decades because of its ability to provide reliable vacuum performance under demanding operating conditions. Piston pumps are known for their durability, efficient operation, and ability to handle challenging industrial applications.

MD Kinney piston pumps are designed to operate in environments where reliability, performance, and long-term service life are essential.
