Husky 3300 Air-Operated Diaphragm Pumps

3 inch Positive Displacement Double Diaphragm Pump

The Husky 3300 has a 3 inch (76.2 mm) connection and is available in aluminum, polypropylene and stainless steel

The Husky 3300 air-operated diaphragm pump features a stall-free low pulsation air valve which provides a smooth and rapid changeover.

 

  • Expanded material offering to handle numerous applications
  • Flow rates up to 300 gpm (1,135 lpm)
  • Modular stall-resistant air valve design
  • Complete 3 inch family of diaphragm pumps available in aluminum or polypropylene center sections
  • Heavy-duty construction
  • Faster change over with spring loaded pilot valves

The one-piece center section eliminates leaks and reduces maintenance on the Husky pumps when compared to other diaphragm pumps.
