GRACO D52977 – Husky 515 PP 1/2″ NPT Standard Pump, PP Center Section, PP Seats, BN Balls & BN

GRACO D52977 – Husky 515 PP 1/2″ NPT Standard Pump, PP Center Section, PP Seats, BN Balls & BN Diaphragm, 100 PSI

Air-operated double diaphragm pump component designed for polypropylene construction with polypropylene seats and Buna-N balls and diaphragm, engineered for reliable fluid transfer applications requiring chemical resistance and durability

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
