Abstract

A pressure and vacuum pump including at least two diaphragm pump heads for providing vacuum and pressure simultaneously. The dual function pump reduces number of required pumps, is traditionally quieter, and enables the system to run at a lower duty cycle. A drive in the pump housing causes a connecting rod to oscillate a diaphragm to move up and down thereby causing air to be either drawn into an inlet or forced out via an exhaust.
