Design and Function

An air control valve supplies the air chambers behind the diaphragms alternately with compressed air. One diaphragm is pressed to the front (= pressure stroke) while the other one is pulled backwards (= suction stroke).

The special design of the air control valve ensures that the pumps can always be approached safely, i.e. that there are no undesirable standstills. The valve balls open and close in the stroke rhythm of the diaphragms.

Materials and options

The medium-contacting parts can be supplied in a great variety of different materials. Materialcombinations coordinated with the application make the pumps suitable also for critical dosing media.
We offer the following materials: PP, PP-CFK, ECTFE, AISI 316, Aluminium, PVDF, PVDF-CFK
