Oil Supported Diaphragm Pumps


The Pyxel Oil Supported Diaphragm Pump is a variable output Pump with high efficiency ball valves.

Available in both high grade uPVC and Stainless Steel 316 Wetted Ends, the Pump is able to handle a variety of aggressive substances with ease.

A Pure PTFE Diaphragm eliminates the necessity of a gland seal, eliminting leakage.

Drive is from a Worm Wheel Gear set, actuating a sprung return Eccentric.

Stroke length, and therefore output is adjustable by means of a manually adjusting micrometer screw giving calibrated adjustment length with a 13:1 turn down ratio.
