Viscous feeding technology
This pumping technology is the most used in the thick world (sealant and adhesives).
Our chop check piston pump are known under the name REXSON.
All REXSON pumps are equipped with a pneumatic motor (power part) and a chop check hydraulic (driven part).
All this pumps are double acting and are fed with a maximum of 6 bar of air.
Operating principle :
- When piston down stroke, Check valve (green) closed against the seat and the material in the chamber V2 is displaced out of the pump by the pump displacement rod.
- When piston up-stroke, check valve (green) opens and material is forced into chamber V2. The top check valve (red) closes and material is pulled from chamber V1.
Can pump products up to 1 million centipoises
