The Azcue AN ATEX 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.
