Heavy Duty Air-Operated Double Diaphragm Pumps

Heavy Duty Air-Operated Double Diaphragm Pumps

Designed to handle abrasive and high-viscosity fluids, these double diaphragm pumps are made of heavy-duty materials, have a thick-wall housing, and feature an all-bolted construction with a mountable base, which results in increased durability and allows them to withstand high pressure. Pumps also have a bottom discharge port to help prevent solids from settling and causing added wear on the pump components.

Their double diaphragm design reduces the possibility of pressure buildup within the pump. They are self-priming and able to run dry for limited amounts of time. Driven by compressed air, these pumps are a good choice in hazardous environments where sparking is an issue, or in areas where electricity isn't readily available.

With Heavy Duty Ball Valve

Commonly used with fluids containing small solids and for high-viscosity liquids, these pumps have a heavy-duty ball valve system which allows for excellent suction lift and high flow rates. These pumps feature variable porting options, including side, top, bottom, and dual, for convenient access. The ball valves are weighted for high consistency when filling the chamber, and the pump components are designed to withstand tough jobs.

With Heavy Duty Flap Valve

With a hinged-flap check valve and a large area for fluid flow, these pumps are designed for use with abrasive chemical slurries and line-size solids in both vertical and horizontal manifold connections. They also have greater suction lift than ball valve pumps.
