The Volumetric pump is suitable for transferring whole, crushed, destemmed and fermented grapes. The product is conveyed by an auger inside the pump and driven into the outlet pipe by an elliptic rotor. The low number of rotor revolutions limits breaking of the skins/seeds and crushing of the grapes, thus providing an excellent quality product. Works great under destemmer/crushers, or to unload a red fermenter. Arguably the most delicate must pump on the market today.
