**Specifications**
How a Diaphragm Pump Works:
The pump is driven by an AC or DC motor. In front of the motor is a valve assembly containing two to five pump chambers. Each chamber has a diaphragm behind it in the lower housing. As the motor shaft turns, an internal cam causes the diaphragms to move forward and backward in a continuous sequence, creating suction. This suction pulls fluid through the inlet, through check valves, and out through the outlet.
