Liquid Ring Pumps: The Hybrid of The Pump Industry
Combining the low maintenance and efficiency of centrifugal pumps with the self-priming nature of positive displacement pumps and the high-pressure capabilities of multistage pumps, side channel pumps make a highly versatile design capable of handling a variety of low viscosity fluids in challenging applications with difficult suction conditioners. As well as being popular for clean fluids including water, light fuels and chemicals, liquid ring pumps as they are otherwise known, are also ideal for fluids containing up to 50% entrained gases with little interruption to fluid flow, including those with air pockets and condensation and ammonia pumped at boiling point. Their high-pressure capabilities also see them regularly selected for installations involving water supply and boiler feed. Our long coupled side channel pumps are easier to maintain and are also more durable for continuous use as they have additional bearings in the pump head to share the strain of operation. So, if it sounds like the liquid ring pump is perfect for your application contact our pump experts for help specifying the model you need today.

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.
