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.

Available here is our guide to the design and workings of a side channel pump, as well as the applications they are ideally suited to.

The RA Reversible Side Channel Pump is manufactured by Azcue Pumps. As the official UK Agent of Azcue Pumps, Castle Pumps are a leading Bombas Azcue supplier in the UK with unrivalled technical knowledge. Azcue Pumps are a European manufacturer with over 100 years’ experience in type approved pumps for marine and offshore applications. Today their pumps are installed in more than 10,000 vessel builds. Whilst originally developed for the marine market, Azcue Pumps’ reliability in applications that depend upon the safety and operation of a ship saw them become a desirable product in industrial applications involving water, fuels and lubricants.

One of the key benefits of the RA liquid ring pump like the other models in the Azcue range, is that is benefits from interchangeable parts for reduced on board stockholding. We guarantee supply of spares for 15 years from model discontinuation for long term pump servicing, saving the user from having to prematurely replace a pump that just needs maintenance.

Azcue RA side channel pump are cast, machined and assembled at their foundry in Spain. Each pump is manufactured to order and designed to fit your process, resulting in greater efficiency and lower overall lifetime cost in terms of wear and energy consumption. Before leaving the factory, pumps are individually tested to confirm performance meets the requirements set out in your enquiry.

Like centrifugal pumps, side channel pumps have narrow tolerances that make them suited to only clean, low viscosity fluid free from solids. However, their uses do vary. Firstly, 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. Their higher pressure capabilities also mean that it can transfer fluid over long distances or through narrow pipework easier than an equivalent centrifugal pump. This makes the Azcue RA liquid ring pump ideal for the below applications:

Marine Applications:Industrial Applications:
  • Desalination/reverse osmosis pump
  • Boiler feed
  • Condensate extraction
  • Fresh water & sea water cooling pump
  • General sea water service
  • Aquaculture recirculation systems
  • Low viscosity fuel and lubrication transfer
  • Condensate extraction
  • Boiler feed
  • Closed loop HVAC circulating & cooling tower pumps
  • General water transfer, supply and service
  • Water pressure boosting pump
  • Swimming pool recirculation systems
  • Low viscosity fuel and lubrication transfer
