Product information

This is the highest capacity double diaphragm pump in its price class. With all the same durable features of the smaller model, the 1590 has 1,5" npt ports that can take on the heavier, more viscous materials and pump them faster with greater tolerance for suspended solids. Model 1590 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
