Aspir Self-Priming Pumps

ASPIR Self-Priming Pumps are suitable for use in food processes, pharmaceutical and chemical industries. It is generally used for the transfer of products at temperatures close to the boiling point such as oil, wine, alcohol, acetone. Its main application is as a CIP return pump.

Gear pump with self-priming feature can transfer the product by sucking from a distance of 4-5 meters. It is extensively used in CIP systems, food applications and fluid transfers containing steam.

ASPIR Self-Priming Pumps Application

Aspir Self-Priming Pump is a sanitary side-channel self-priming pump suitable for use in the food-processing, pharmaceutical and chemical industries. It is specially designed for pumping products containing air or gas, and it can also be used for negative suction with prior priming as well as in filtration equipment.

It can be used to pump wine, oil, syrups, volatile products such as alcohol, acetone and other solvents, or products at temperatures close to the boiling point. However, the main use of this pump is for CIP return.

Operating principle

The impeller is housed between the suction casing and the diffuser, it rotates in conjunction with the pump shaft. Due to this arrangement, the rotation of the impeller and the position of the side channel, negative pressure is created inside the suction casing, which generates the suction force of the pump. At the same time, the fluid receives energy in the form of kinetic energy and pressure energy, and this impels it through the discharge casing

side-channel Design and features

Aspir Self-Priming Pump is a range of centrifugal pumps made of a cold-formed stainless steel discharge casing, cast sainless steel suction casing, diffuser and lantern, star-shaped fixed impeller, and an external mechanical seal that prevents any contact of the spring with the product.

The motor complies with the IEC standards, it is protected with a stainless steel shroud made of stainless steel sheet and provided with the height adjustable hygienically designed legs
