The Sero SRZ series self-priming side channel pumps are designed for high flow, high pressure and high temperature applications. The side channel pump design is capable of pumping aerated liquids as well as low viscosity fluids without the presence of abrasive particles.
The SRZ range of self-priming pumps are available with a standard mechanical seal and double mechanical seal or magnetic coupling for more extreme and high temperature applications. Suitable applications for this liquid ring pump include high temperature, refrigerants, fuel transfer, LPG, pressure boosting, sea water transfer and boiler feed.
