Air-operated diaphragm pumps that keep running
Self-priming, dry-run safe and deadhead-safe. Seven sizes from 1/4" to 3", in six body materials, configured to your duty — with center-port or in-line side-port connections.
Built for difficult fluids
No electricity at the pump
Compressed air drives the pump, so there is no motor, no dynamic seals and nothing to burn out. Flow and head adjust by throttling the air supply — stall it against a closed valve and it simply waits.
Handles what other pumps cannot
Runs dry without damage, self-primes with suction lift, and moves viscous, abrasive and solids-laden fluids with a low-shear action. Solids up to 9.4 mm on the 3" size.
Configured, not compromised
Choose body, seat, ball and diaphragm materials independently — polypropylene, PVDF, aluminium, cast iron, 304/316 stainless, PTFE, Santoprene, Viton, Buna-N and polyurethane — so the wetted path suits the fluid, not the other way round.
