Pump for the pharmaceutical industry RV

centrifugalfor liquidsclose-coupled

The RV centrifugal pump with helicoidal impeller is the best solution for the transfer of liquids with solid particles 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., e.g. solid particles suspended in water (proportion: 40% to 60%). It is ideal for applications of the transfer of pieces of fruit or whole fruits, olives, mushrooms, slices of orange, vegetables, fish, etc. RV pumps are widely used in wineries for the pump-over process where the high capacity and minimum destruction of the solid parts (seeds, skins, etc.) is required. The design of the pump contributes to a better extraction of tannin, the coloring matter of wine, in the phase of vinification, reducing the lees formation and, as the result, achieving high quality wines. Operating principle Due to the helicoidal shape of the impeller and to the flow optimised to avoid the obstruction of the pump, solid particles pass through the pump without being damaged.
