The Azcue MA Close Coupled Side Channel Pump is the entry level side channel pump in the range, with low pressure and flow capabilities because of its single impeller design. This model is usually selected when the flow requirements of the application are too low for the MO, BR and BR-RR. By nature, these liquid ring pumps can handle up to 50% gas content, making the MA side channel pump suitable for applications such as condensate extraction.

These Azcue pumps have a separate shaft in the pump head and motor meaning that if one shaft goes, there is no need to replace it all; a benefit over other pumps on the market that have one continuous shaft from head to motor. The Azcue MA horizontal pump has a back pull out design, meaning that the motor can be removed without disconnecting the pump from the pipework, saving time and effort when maintenance is required. Whilst being closed coupled, this liquid ring pump has a lantern bracket, which means that whilst being compact, there is still space between the pump and motor. This means that if the seal wears, no water will fall into the motor.

The MA Close 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 MA 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 MA 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 MA liquid ring pump ideal for the below applications:
