(0)
The new PD01 series 1/4" pump is a replacement for the current PD02 series diaphragm pump from Ingersoll Rand. A double diaphragm positive displacement pump that uses two sets of flexible membranes to pump fluids and a series of check valves. This ensure fluid can only travel in one direction through the chamber. Pump cycling begins as air pressure is applied.
