Azcue AN VP/EP Long Coupled Self Priming Centrifugal Pump

The Azcue AN VP/EP Centrifugal Self Priming Pump is essentially the AN long coupled centrifugal pump complete with either a vacuum or electric priming pump for installations with difficult suction conditions. The vacuum priming pump would be the better solution for longer suction distances thanks to its ability to dry run for short periods of time.

The AN is a large, heavy duty horizontal centrifugal pump with good flow and pressure capabilities. As it is long coupled, this model of centrifugal water pump is easier to maintain as you can access the pump head without having to remove the motor first, and is also more robust for continuous use thanks to the additional bearings in the pump head to share the strain of operation.

Based on DIN 24255, the Azcue AN is manufactured dimensionally the same as other pumps allowing the direct replacement of existing single stage centrifugal pumps from other manufacturers, for applications involving clean fluids such as water and low viscosity fuels. As it can be supplied with a double mechanical seal cooling system, fluids are able to be handled up to 190°C which makes the AN suitable as a thermal oil pump.

This series of self priming centrifugal pump have a back pull out design, which allows the motor to be removed without disconnecting the pump from the pipework, and maintenance to be less time consuming and complex. Thanks to the wear rings, there is small clearance between the impeller and pump casing, preventing wear to these parts. Wearing rings are designed to be replaced every now and then, preventing the more expensive replacement of the impeller or casing.

These Azcue pumps also 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.

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 self priming centrifugal 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:
