Vacuum and Self-Priming Technology
While standard centrifugal pumps lock up when there is air in the suction line, Self-Priming pumps create a vacuum by evacuating the air inside thanks to their special casing design. It is the most ideal and hygienic solution for drawing liquid from underground tanks or evacuating foamy washing water in CIP systems.

Technical Specifications and Capacity
* Suction depth and flow values may vary depending on the fluid's viscosity (water = 1 cPs) and ambient temperature.

Frequently Asked Questions
What is the working logic of a self-priming pump?
During the initial installation, a certain amount of liquid is filled into the casing. When it runs, it mixes this liquid with the air in the suction line and expels it, then draws the liquid up from the bottom thanks to the vacuum created in the line.
Why is this pump used in the CIP return line?
During the tank washing (CIP) process, a lot of air and foam mixes with the liquid. Normal pumps spin uselessly in the foam (cavitation), while self-priming pumps tolerate the air and transfer the washing liquid without issues.
