The Azcue BR Side Channel Pump is the long coupled equivalent to the MO close coupled pump. This is a larger, robust pump, multistage in design, which gives it very high pressure/suction capabilities whilst having low flow. This makes it ideal for applications such as pressure boosting and water supply when there is quite a lot of demand on the supply at a time. By nature, these liquid ring pumps can handle up to 50% gas content, making the BR side channel pump ideal for condensate extraction.

The Azcue BR horizontal multistage pump has a back pull out design, allowing the motor to be removed without having to remove the entire pump from the installation, saving time and effort when maintenance is required. Being long coupled, the BR liquid ring pump is easy to maintain as you can get to the pump head without removing the motor first, and is more durable for continuous use thanks to its additional bearings in the pump head to share the strain of operation

These Azcue pumps have two separate shafts in the pump head and motor meaning that if there is an issue with one, there is no need to replace it all; a benefit over alternative brands that have one continuous shaft from head to motor.

The BR Long Coupled 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 BR 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 BR multistage 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 BR liquid ring pump ideal for the below applications:
