PROGRESSIVE CAVITY PUMPS

The basis of any Progressive Cavity Single Screw Pump is a power section which usually consists of a metal rotor (n-start external helix) and a rubber stator (n+1-start internal helix). Rotation of the rotor inside the stator creates sealed cavities that progressively move from suction to discharge side of the pump producing differential pressure.

Machine for force feed of high viscous media

SOLTEC ® company Novomoskovsk Mechanical Plant realizes successfully the projects over pumping tomato paste with a high concentration of dry solids - up to 35-40 %. Such concentration of the product is characterised by low mobility and sedimentability that leads to paste hang - up in the throat of the pump.

To decide this task SOLTEC ® company Novomoskovsk Mechanical Plant has developed the option to the pump as a device of force feed with blades rotating to each other. It allows to move paste mass not allowing it to hang -up above the screw conveyer of the pump and provides the continuous volume of high viscous mass in the its chamber.
