Highly efficient diaphragm pump

Looking for an efficient way to pump out bilge from your boat? Well, the Seaflo 33 Series Automatic Diaphragm Pump features no moving parts in the airstream, perfect if you hate those noisy pumps.. It's a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or Teflon diaphragm and suitable valves either side of the diaphragm to pump a fluid.

How a Diaphragm Pump Works
In front of the motor is a valve assembly containing two to five valve pump chambers. Each valve chamber has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating a suction. As this suction builds, fluid is pulled through the inlet, through the various valve chamber check valves to the outlet.
