Hose pumps dedicated to the food processing industry belong to the category of peristaltic pumps, which are a type of rotor-type volumetric pump named after it can transport gas, solid and liquid three-phase media with the same operating principle as the digestive tract. There is no exact distinction between hose pumps and peristaltic pumps. In general, peristaltic pumps refer to a small flow rate (ml/min) and a low outlet pressure (less than 3 kg/cm2) and are mainly used for measurements in hygiene applications and laboratories. Hose pumps refer to large flow rates (up to 80 cubic meters per hour) and high output pressures (up to 16 kg/cm2), and are mainly used to transport and measure large industrial flows. Hose pump designers and users first evaluate their ability to transfer strong abrasive media. There are no valves or seals. Only the inner cavity of the rubber hose is in contact with the medium. The rotor of the compression hose is completely independent of the medium. If you want to use a hose pump to pump a variety of materials in a food factory, you only need to replace the different types of hose pump heads.

In addition, hose pumps have many unique features. No pump has a better self-absorption capacity than a hose pump and can create an almost perfect vacuum to suck in liquids. It delivers high viscosity. Shear-sensitive media is also an advantage. The fixed displacement per revolution has nothing to do with the outlet pressure and is a natural metering pump.

In fact, in addition to the quality of the hose itself, the main factor that determines the life of the hose is the number of times the hose is compressed. The second factor is the compression method of the hose, its strength and the resulting heat of friction. In other words, hose failure is due to fatigue lepies due to the cumulative mechanical frictional heat of the compressed water. The best way to maximize hose life and reduce downtime intervals is to compress your hose accurately using compression methods that reduce the number of times the hose is compressed and minimize damage to the hose.

When the peristaltic pump is used in the food factory, it can save time and money because the pump does not need to be further disassembled. Since the product is completely contained in the tube, there is no risk of bacterial growth in the tube pump, and there are no dead spots where bacteria can accumulate. The suction effect means that the tube can be sufficiently cleaned and the pump can drain itself. In addition, food grade pipes can be sterilized in any normal way, and only the contact part of the pipe can be easily replaced, minimizing regular sterilization costs. This highly accurate hose pump can provide repeatable metering to add flavor, color and additives. The error can guarantee up to 0.5% ± the weight error of the additive.
