The Husky 515 has a ½ inch (12.7 mm) connection and is available in polypropylene, acetal and PVDF

Kust osta

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. 

Benefits of the Husky 515 double diaphragm pump

  • 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
