GRACO D51311 – Husky 515 AC 1/2″ NPT Standard Pump PP Center Section SS Seats PTFE Balls & PTFE

GRACO D51311 – Husky 515 AC 1/2″ NPT Standard Pump PP Center Section SS Seats PTFE Balls & PTFE Diaphragm, 100 PSI

Husky 515 air-operated double diaphragm pump component featuring acetal construction with SST (stainless steel) seats and PTFE balls and diaphragm for reliable chemical compatibility and performance in industrial fluid handling applications

The Husky 515 air-operated double diaphragm pump features a stall-free low pulsation air valve which provides a smooth and rapid changeover.

The bolt through fluid cover design eliminates leaks and makes the Husky safer with higher reliability.

Center and end porting options.

No mechanical seals to cause fluid leaks or failures

Runs quietly at less than 85 dBa with easy-to-use remote muffler capability for even lower noise levels

Easy-to-service air valve and ball checks

Operates on as little as 20 PSI (1.4 bar, 0.14 MPa)

Split manifold option to pump multiple fluids without mixing

Delivery up to 15 gpm (56.7 lpm)

Reliable air valve for years of dependable performance
