ASPIR Side Channel Pump

The Inoxpa ASPIR pumps are self-priming, sanitary side-channel units suitable for the food-processing, pharmaceutical and chemical industries. They are known for their outstanding gas-handling capabilities, allowing for the smooth transfer of liquids with up to 50% air or gas content.

While the primary function of these pumps is for CIP return, they can also be used in wine, oil, syrups, and volatile products, as well as fluids with temperatures close to boiling point.

Principle of Operation

Side channel pumps follow part of the operating principles and characteristics of both positive displacement pumps and centrifugal pumps. During start-up, the pump acts like a positive displacement pump as it self-primes but as the fluid reaches the side channel, it acts like a standard centrifugal pump.

These pumps usually come in two or more stages where the component of each stage include the suction disk, star impeller, and discharge disk which has a side channel that is open at just one point rather than the entire circumference.

The liquid enters through the suction and hits the impeller blades and side channel. As the impeller rotates, the fluid moves back and forth several times between the impeller blade and the side channel, generating a strong transfer of energy. This movement results in a pressure increase up to 10 times greater than the force created in a centrifugal pump rotating at the same speed.
