Main Features
Liquid End
1. The form of bypass oil replenishment, hydraulic driven diaphragm, has a longer lifespan.
2. Built in adjustable safety valve automatically protects the diaphragm and pump head from overpressure damage.
3. The high-precision one-way valve structure ensures precise feeding of materials.
4 PVC、PVDF、316SS, Multiple pump head materials such as Hastelloy 20, Hastelloy C22, and PTFE lined steel are available, suitable for conveying various materials.
%1. Optional pressure type double diaphragm detection (on-site/remote) alarm.
Drive End
1. Unique eccentric worm gear - body structure,
2. Compact structure, precise travel, and small installation space for equipment.
3. Wear resistant ball bearings make work more stable.
4. Oil bath lubrication prolongs the working life of driving components.
5. Flow can be adjusted in both shutdown and operation states, and the adjustment method can be manual or variable frequency.
Main Application
Environmental protection, petrochemicals, chemicals, refining, electricity,metallurgy, pharmaceuticals, chemicals, wastewater treatment, and other fields.
