OVERVIEW

PRODUCT DESCRIPTION

Unique eccentric worm gear integrated structure, compact mechanism, accurate stroke, small equipment installation space.

Wear-resistant ball bearings make the work more stable.

Oil bath lubrication, long working life of driving parts.

The flow rate can be adjusted in the stop or running state, and the adjustment mode can be selected by manual or frequency conversion.

In the form of bypass oil replenishment, the hydraulic drive diaphragm, the diaphragm life is longer.

Built-in adjustable safety valve automatically protects diaphragm and pump head from over-pressure damage.

The structure of high-precision one-way valve ensures the accurate addition of materials.

PVC, PVDF, 316SS, Hagin 20, Haskin alloy and other pump head materials are optional, suitable for conveying all kinds of materials.

Optional pressure double diaphragm detection (local / remote) alarm.

 

FEATURES AND ADVANTAGES
