Multi Stage Liquid Ring Pumps for Clean Fluids & Gas Content
Castle Pumps have been supplying pumping solution to the industrial and marine market for over 10 years, meaning we have extensive product knowledge and experience and can help you select the right pump for your application. Our range of multistage side channel pumps is ideal for higher pressure applications such as pressure boosting, boiler feed and reverse osmosis. Thanks to their design multistage side channel pumps are able to achieve higher performance with a smaller motor size and using less energy. Our multistage side channel pumps can handle high temperature fluids that are pumped close to boiling point and can pump fluids that contain up to 50% gas content with little interruption to fluid flow.

FAQs
Side channel pumps, or liquid ring pumps as they are otherwise known, are somewhat of a hybrid between a positive displacement pump and a centrifugal pump. Upon start up, a side channel pump begins to operate like a positive displacement pump as it self primes, but soon begins to act like a centrifugal pump once the side channels become filled with fluid.
The liquid is drawn in and enters the impeller blades and the side channel which is open at just one point in the casing, rather than the entire circumference. As the star shaped impeller rotates, the pumped fluid moves back and forth several times between the blades of the impeller and the side channel. This creates a strong transfer of energy and results in an increase in pressure up to 10 times greater than that of centrifugal pump rotating at the same speed.
They are usually designed for low flow, high pressure applications involving any low viscosity, clean fluids and chemicals including those at high temperatures with entrained gas or vapour content up to 50%.
Due to their narrow tolerances, side channel pumps are unable to hande solids. All liquids pumped must be clean and free of particles.
Yes! As the fluid collects in the outer area of the side channel and impeller blades, a liquid ring forms to facilite the self-priming process like a positive displacement pump, making it ideal for difficult suction conditions.
Unfortunately not. The high internal velocity/force that is applied upon the fluidlike a centrifugal pump can damage or alter the consistency of a delicate fluid.
