The Azcue MO Close Coupled Side Channel Pump is a larger, more robust alternative to the MA side channel pump. Its multistage design gives it very high pressure/suction capabilities whilst having low flow, which makes it suitable 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 MO side channel pump ideal for condensate extraction.

The Azcue MO 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. 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 fluid will fall into the motor. It also benefits from having additional bearings to share the strain of operation, therefore enhancing the robustness when in continuous use.

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.

Emergency Seawater Circulation Pump Replacement for Subsea Support Vessel

Emergency Seawater Circulation Pump Replacement for Subsea Support Vessel

Castle Pumps are committed to providing the best possible support and service to customers, so when an emergency pump is required, we strive to provide one in a preferable time frame. An enquiry for an emergency replacement pump was received after hours on a Friday, needed for installation Monday morning whilst the vessel docked. By working out of hours and supplying from our 'from stock' range, we were able to deliver on time.

The MO 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 MO 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 MO 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 MO liquid ring pump ideal for the below applications:
