Double Diaphragm Pumps Further Increased Pump Safety

Editor: Dr. Jörg Kempf

The E-Series, made of PE conductive and PTFE conductive, represents the latest generation of Almatec’s plastic air-operated double diaphragm pumps made in solid design.

As common, the housing parts are tightened to each other via housing bolts. However, instead of single bolts pressing punctually against the housing, all housing bolts are now tightened against a diaphragm-sized ring per side. This structure results in a more even spreading the housing bolt force and in an increased permissible bolt torque — in the end an increased pump safety. The flow resistance is reduced via an optimised flow pattern to increase the efficiency factor.
