Winery Pumps

(book excerpts)

Selection of a proper pump is important to efficient winery operation. Pumps can provide a winemaker with the ability to transfer the must from a de-stemmer/ crusher to the tank for fermentation. They can also be used for pump-overs in fermentation tanks to allow for color enhancement on red wines and provide a way to move the wine from the tank to barrels for maturation. Pumps are also used to move the wine to filters to remove sediment or solids and then to move the wine to the bottling line for packaging. Several factors need to be considered when choosing pump(s) for must, lees, juice, and wine transfer of which all vary in terms of viscosity and density. Usually, wine has a very low viscosity, whereas crushed grapes or grape must have a very high viscosity. Therefore, the choice of pump will depend on pumping requirements (i.e., what is being moved) as well as the distance and the height where a product needs to be transferred. Several other factors that also need to be considered which include: pump size and capacity, cost of operation, material of construction, and ease of cleaning, and maintenance. Certain pumps are better suited for specific pumping tasks, while some pumps are more versatile and can be used for pumping at any stage of the process.
