The self-priming pump is specifically designed to transfer liquids containing air or gases without losing its pumping capacity.
Specifically, this type of pump can independently eliminate the air in the suction duct during the start-up phase.
It is generally used to empty tanks, where air or gas mixes with the liquid in the suction duct.
The air sucked into the pump emulsifies with the moving liquid contained in the pump body.
The air-liquid emulsion is pushed into the ignition chamber where the lighter air separates and exits the delivery tube; the heavier liquid falls back into circulation.
Once all the air is ejected from the suction duct, the pump gets triggered and works like a normal centrifugal pump.
The sanitizable AISI 316 L stainless steel self-priming pumps are recommended when effective cleaning is required for food safety and excellent resistance against corrosion.
They provide high production quality, robustness and long-term reliability, considerable wear resistance, direct coupling with electric motors and low prices.
Self-priming pumps
Smooth
surfaces and specific seals allow to widely meet the IP69K classification (the highest degree of protection for a pump); ideal solution for CIP (Clean-in-place), SIP (Sterilization-in-place) applications and high-pressure washes (even with high-temperature water and/or with the addition of aggressive detergents), in a humid environment and in all sites where cleaning is planned on site, guaranteeing efficiency over time.
It is assembled in modules, which allows, over time, to replace the worn mechanical seal, favoring total inspection and maintenance. The volute and pump body are polished in order to limit turbulence and significantly reduce the noise that self-priming pumps produce.
This leads to higher quietness and security.
