The Sero SRZS series of side channel pumps are self-priming liquid ring pumps ideal for high flow, high pressure and high temperature applications. The side channel pump design enables this range to deal with aerated fluids and low viscosity liquids.
The SRZS 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. There is also the option of a canned motor. This liquid ring pump is commonly used for high temperature, refrigerants, fuel transfer, LPG, pressure boosting, sea water transfer and boiler feed applications.
For further information on this pumps working principle and its typically applications, read our side channel pump guide.
