The Graco Husky 1/4-inch pneumatic double diaphragm pumps offer true-formed PTFE and Santoprene diaphragms for enhanced performance and is available in polypropylene, groundable acetal and PVDF.
The Husky 515, 1/2 inch (12.7 mm), pneumatic double diaphragm pumps operate on as little as 20 psi (1.4 bar, 0.14 MPa) and is available in groundable acetal, polypropylene and PVDF materials of construction.
Husky 1050 pneumatic double diaphragm pumps feature a stall-free, low pulsation air valve which provides a smooth and rapid changeover. Available in aluminum, polypropylene, conductive polypropylene, PVDF, stainless steel and hastelloy fluid sections.
The Husky 1050HP is the first pump on the market that allows users to choose between low pressure and high pressure operating modes with Graco’s low-high pressure mode valve. High pressure operation isn’t always required, so switch to the low pressure mode to reduce air consumption up to 50%. These features, combined with the quality and reliability of our standard Husky diaphragm pump design; make this one of the most unique high pressure diaphragm pumps on the market.
This 1-1/2 inch pneumatic double diaphragm pump offers a patented, high-reliability closed center air valve that is online serviceable and an epoxy-coated air section for tough environmental conditions.
Husky 15120 pneumatic double diaphragm pumps have a single piece polypropylene center section for increased reliability and chemical compatibility, plus a patented, high-reliability modular air valve that is online serviceable. Design improvements include the overmolded frame which provides improved reliability and helps to eliminate fluid leakage and an updated diaphragm design that increases flow with flow rates up to 120 gpm (454 lpm) – making it one of the most efficient pumps on the market.
Husky 2-inch pneumatic double diaphragm pumps offer larger ports for increased flow, along with a patented, high-reliability closed center air valve that is online serviceable.
Husky 2200 pneumatic double diaphragm pumps have a single piece polypropylene center section for increased reliability and chemical compatibility, plus a patented, high-reliability modular air valve that is online serviceable. Design improvements include an overmolded frame for improved reliability and will help to eliminate fluid leakage and an updated diaphragm design that increases flow with flow rates up to 200 gpm (757 lpm) – making it one of the most efficient pumps on the market.
Husky 3300, 3 inch (76.2 mm), pneumatic double diaphragm pumps feature a four bolt joint design, which provides even sealing pressure for leak-free operation and a three-piece manifold for increased installation flexibility. Available in aluminum, polypropylene and stainless steel.
Graco’s ChemSafe pumps feature PTFE or UHMWPE (ultra high molecular weight polyethylene) corrosion-resistant fluid paths, which make them ideal for corrosive and abrasive chemicals. There’s no exposed metals and they can be configured in various materials to meet most abrasion, temperature, and chemical compatibility requirements. Plus they’re dead-head capable and achieve high flow rates while minimizing air consumption and operational noise.
Max flow rate of 85.2 gpm (322 lpm). High quality machined design provides a precision fit and superior chemical containment compared to molded pumps. Corrosion-resistant exterior with no exposed metal reduces maintenance, extends pump life and offers clean, safe operation. Removable air motor offers easy and intuitive maintenance ensuring maximum pump performance and availability. Ideal for corrosive and abrasive liquids such as acids, fuels, glues, paints, resins, inks, or wastewater.
