Air Operated Double Diaphragm Pumps

Double Diaphragm Pumps are designed for use in applications requiring large volume transfer in a short time
Driven by compressed air, these can transfer contaminated media & are very useful for cleaning out pits with mixed liquids such as oil, water etc.
Handle a wide variety of fluids with solid content: as there are no close fitting or rotating parts
Self priming: pump is designed for high suction lift even at dry start up & also with heavier fluids
Ability to run dry: as there are no close fitting or sliding parts
Portable / simple installation: Simply connect air supply line & liquid line; pump is ready to perform
Explosion proof: safe pumps since they are operated by compressed air
Pumping efficiency remains constant: no rotors, gears or pistons that wear over time, hence no decline in performance
All pump models are designed for use with an inlet air pressure of 20-100 PSI

Air inlet threaded 1/4″ NPT (F) Pumps are available in a choice of 2 materials:

Aluminium body with a Hytrel* diaphragm. Thesecan be used for all high temperature applications
