This diaphragm fluid pump is suited for circulating oils in transmission and differential cooling systems. It can also be used for other applications like circulating coolant for water radiators, intercoolers and driver cool suits. The motors utilize a ball bearing drive throughout and an integral cooling fan for long life.

  • 265°F temp rating.
  • 3/8" NPT female inlet/outlet connections.
  • Viton diaphragm can be used with corrosive fluids.
