Diaphragm Pumps

Pygme Diaphragm

This diaphragm pump is a fixed output single action pump with highly efficient ball valves. The wetted parts are made from high grade plastic to enable compatibility with a wide range of aggressive liquids. The absence of any gland results in zero leakage.

Driven from a vertical flange mounted motor through a worm and wheel eccentric assembly results in a consistent and reliable pump.
