The Ragazzini peristaltic pump is both versatile and gentle when transferring the valuable products at wineries. The pump is capable of transferring not only the wine, but whole grape bunches, whole berries and even the red fermented grape skins after the fermentation process.

Ragazzini Peristaltic Pumps

Ragazzini peristaltic pumps operate at low speeds, so the transfer is done more gently than any other transfer process. This delicate treatment of the product ensures no crushing or tearing of stems, skins or seeds, which results in a decrease in the percentage of LEES produced, by up to 32%. They are ideal for pumping over during fermentation with a total control of exposure to oxygen. Oxygen can either be minimised or added if desired.

Pumps can be equipped with a variable frequency drive which enables a 1-10 turn down ratio, giving operators a very large operational flow range. Units can also be used with matching screw feeders for grapes and grape bunches, or the screw feeder swapped for a flange and pulsation dampener to turn it into a wine pump. This gives wineries a very versatile [and gentle] transfer unit.

Peristaltic pumps have many advantages over other types of pumps. Besides being the gentlest of pump types, peristaltic pumps do not have seals or valves. No seals means less chance of air ingress and no issue with contamination. There are no moving parts in the fluid and it is a totally sealed pumping system. Peristaltic pumps are self-priming [to 8.5m] and can be operated dry without damage. Pumps can also be run in reverse to empty or fill tanks.

Ragazzini’s pumps are available with flow rates from 400 litres per hour up to 180,000 litres per hour. They are available with wheel kits for portability and screw feeders for versatility.
