Rotary Piston

Rotary Piston Vacuum Pumps - PTB Sales, Inc.

PTB has been selling refurbished rotary piston vacuum pumps for almost two decades. We have factory trained technicians utilizing the proper tools and our own time tested quality standards: OEM specifications are met during inspection, assembly and test.

Piston pumps are used for most large scale vacuum applications. These pumps have a sliding sleeve through which the gas enters, then drawn into a cylindrical chamber and exhausted by a rocking piston plunger. These pumps are very hardy and have pumping speeds that range from 15 cfm to 2,000 cfm and the pumps can reach a pressure of 1 x 10-4 Torr. Rotary piston pumps can be prepared for corrosive and oxygen service.
