Applications

• The Aspir 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 materials containing air or gas, and it can also be used for negative suction with prior priming as well as with filtration equipment.
• It can be used with wine, oil, syrups, volatile products such as alcohol, acetone and other solvents, or with products at temperatures close to boiling point.
• However, the main use of this pump is for CIP return.

Operating principles

The impeller is housed between the inlet body and the venturi casing and it rotates in conjunction with the pump shaft.This arrangement, together with the rotation of the impeller and the arrangement of the side channel, creates a negative pressure inside the inlet body, 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 impeller casing.

Design and features

• Casing manufactured with cold-formed plate.
• Stainless steel investment casting inletbody and venturi.
• Star-shaped floating impeller manufactured with investment casting technology.
• External mechanical seal that prevents contact between the springs and the pumped fluid.
• Very robust stainless steel-cast lantern.
• Pump support of stainless steel.
