Product information

This is the highest capacity 2-inch double diaphragm pump in its price class. With all the same durable features of the smaller model, the 2150 has 2 in. npt ports that can take on the heavier, more viscous materials and pump them faster with greater tolerance for suspended solids. Model 2150 has an air valve system that is 100% serviceable without disassembly of the wetted parts, saving valuable maintenance time. This pump requires no air line lubrication, which also saves money.

Highest reliability air valves for no stall operation No Lube air valves reduce routine maintenance High flow design with complete range of diaphragm options Rugged construction for long, trouble free performance Ideal for spill response (SOPEP pump) and all types of transfer applications incl. bilges Typical fluids handled by this pump: Oil: Light oil, gear oil, mineral oil Fuel: Diesel, leaded petrol/gasoline, fuel oil Other: Seawater/brine, general waste water, white spirit, alcohol
