Azcue AN Long Coupled Centrifugal Pump

The Azcue AN Horizontal Centrifugal Pump is the long coupled version of the MN; a large, heavy duty pump with good flow and pressure capabilities. Being long coupled, this model of single stage centrifugal pump is easier to maintain as you can get to the pump head without removing the motor first, and is also more durable for continuous use as it has additional bearings in the pump head to share the strain of operation.

Based on DIN 24255, the Azcue AN is manufactured to be the same dimensionally as other pumps enabling the simple replacement of existing horizontal centrifugal pumps from other manufacturers in installations concerning relatively clean fluids such as water and low viscosity fuels. As it is available with a double mechanical seal cooling system, fluids are able to be handled up to 190°C which also sees the AN suitable as a thermal oil pump.

This model of centrifugal pump benefits from a back pull out design, which allows the motor to be removed without disconnecting the pump from the pipework, and the maintenance process to be less time consuming and complex. Thanks to the casing wear rings, there is small clearance between the impeller and pump casing, preventing wear to these parts. Wearing rings are designed to be replaced periodically, preventing the more costly replacement of the impeller or casing.

These Azcue pumps have separate shafts in the pump head and motor meaning that if there is ever an issue with one shaft, 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. If required, the AN centrifugal water pump is available with an external vacuum or electric priming pump. For longer suction distances, a vacuum priming pump would be the better solution thanks to its ability to dry run for short periods of time.

The AN Long Coupled Centrifugal 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 AN single stage centrifugal 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 AN centrifugal water 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.

Single stage centrifugal pumps are the most common pump type for the transfer of low viscosity fluids in high flow rate and relatively low-pressure installations. The centrifugal pump design is often associated with the transfer of water, but is also a popular solution for handling thin fuels and chemicals. This makes the Azcue AN long coupled centrifugal pump suited to applications including:
