SCHARAUBENKREISELPUMPE RVi

Application

The RV pump is the best solution for the transfer of liquid/solid blended products or medium viscosity products that cannot be pumped with an ordinary centrifugal pump.
Due to the helicoidal shape of the impeller, the transfer of the product is gentle and without clogging.
It is ideal for applications of the transfer of semi-finished products, product remains, waste, etc. in the food-processing industry and vanishes, glues, wastewaters in the chemical industry.
In comparison with the the RV_XX range, the RV_XXR pumps are provided with a bearing suppport in the lantern for work with viscous products and for applications provoking an increased axial stress.

Operating principle

Due to the helical shape of the impeller, the pump lets solid particles pass without destroying their structure and the flow is optimized to avoid its obstruction.
