RV Helicoidal Impeller Pump
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 colouring matter of wine, in the phase of vilification, 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.

The advantages of RV pumps are

• Lower energy input to the wine (lower temperature) thanks to their excellent design with CFD tools
• Low energy consumption thanks to their high performance
• Low maintenance
• RV pumps can handle must with solid particles without clogging, so there is no need to place a grid to serve as strainer in the tank
• Food-grade materials comply with EC-1935/2004 and FDA regulations
• Motor in compliance with the IEC and NEMA standards
