Without special winemaking equipment, it is impossible to create a high-quality alcoholic drink that meets all the necessary organoleptic and chemical standards. An important role in the production of wine at all stages is played by pumping devices - pumping systems for winemaking. Piston pumps from the Techno-T company are one of the pumps with high performance and reliability. The units are capable of transporting all types of liquids – from pulp and wort (mash pumps) to wine ready for bottling.

Features of the operation of the piston pump in winemaking, axial-piston and centrifugal pump systems have become the most widespread. To meet the needs of winemaking, double-acting piston pumps are most often used. They include working and guide cylinders with pistons and a valve box consisting of two chambers with four valves. The discharge and suction chambers combine a channel through which performance can be varied. Such a system leads to an almost complete absence of pulsation and an increase in the efficiency of the unit's functioning. The flow of the transported liquid is uniform, without whipping and foaming.

Unlike a centrifugal device, in which the injection and suction of liquid raw materials produce centrifugal forces, under the influence of the rotation of an impeller with blades placed in a casing, pistons are made in a reciprocating pump. After turning on the engines, the working elements (pistons) perform reciprocating movements (like a hydraulic press), as opposed to the rotation of the impeller or vane wheel in centrifugal pumps. Due to the translational movement of the piston, a low-pressure area with rarefied air is formed in the working casing, which contributes to the absorption of moisture inside. At the same time, the valve prevents the penetration of liquid back into the suction channel. At this time, the injection pipeline is opened, where the raw material is sent in liquid form.

All parts of the piston pump that come into contact with the pulp, must and other high acidity wine material are made of food-grade stainless steel, resistant to corrosion and active chemicals.

Tasks facing reciprocating pumps

In winemaking, many factors affect the preservation of the properties of the final alcoholic product, its taste, color, aroma and other organoleptic characteristics. This is not only the variety and degree of maturity of grapes, crushing, pressing, filtering and other technological processes, but also the duration of interaction of wine material with air. This is especially important when transporting liquid raw materials and finished drinks from one container to another. Therefore, pumping equipment is indispensable for the following winemaking operations:

• Pumping of wort into tanks.
• Fermentation.
• To improve the color characteristics of red wine varieties.
• Transportation for exposure.
• During filtering.
• Supplies for bottling and packaging, etc.

Piston pumps are widely used in winemaking for pumping pulp, wort, yeast and adhesive precipitates. In the food industry, thanks to the devices, beer and its components, sediment from vegetables, liquid that does not contain solid fractions, as well as dairy products, juices and water are efficiently transported.

What criteria should be paid attention to when choosing a piston pump?

Pumping piston equipment has the following characteristics:

1. The working parts of the unit must be made of food grade stainless steel. This especially applies to those elements that directly interact with liquid media.
2. Careful impact on transported raw materials.
3. Reduction of exposure to air, which prevents oxidation and preservation of wine aroma.
4. Compliance with sanitary and hygienic requirements. This means that all pump assemblies and mechanisms are easy to disassemble, clean and reassemble. The sterility of the equipment allows you to avoid microbiological contamination of the finished product.
5. The possibility of functioning in the reversible mode.
6. The presence of a safety device that protects the device from overload and increasing pressure inside the pipeline channel.
7. The temperature of raw materials for pumping is up to 85 degrees.

In addition, when choosing a device, it is desirable to focus on current production tasks. Therefore, it is also important to consider the supply volume, pressure, power, mobility or stationary of the device.
