The Azcue RA Side Channel Pump is a reversible design of liquid ring pump that can pump in either direction. This makes it ideal for emptying or filling tanks either side of the pump, and for pumping any remaining water left in the pipework after operation has been completed. Its ability to handle up to 50% gas content makes it popular for applications such as condensate extraction and boiler feed.

The RA model of liquid ring pump is supplied bareshaft as standard, with the option to have it clutch/pulley driven. These Azcue side channel pumps are easy to maintain pumps as they can be quickly dismantled through removal of the front cover plate giving access to internal components.

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.
