The Azcue BOB ATEX Long Coupled Centrifugal Pump is a much larger pump with greater flow and pressure capabilities than the other horizontal centrifugal pump models. Designed for installations concerning relatively clean fluids such as water and low viscosity fuels, its performance makes it suitable for larger volume water transfer applications, the cooling of really large equipment and firefighting where masses of flow is required.

Its long coupled design means that this model of single stage centrifugal pump is easier to maintain as you can get to the pump head without removing the motor first. It is also more durable for continuous operation as it has additional bearings in the pump head to share the strain.

Thanks to its flexible rather than rigid coupling, the BOB centrifugal water pump is able to absorb vibrations better within the installation. This is a back pull out centrifugal pump, which means the motor can be removed without disconnecting the pump from the pipework, making the maintenance process quicker and simpler. This model has wear rings, which means there is small clearance between the impeller and pump casing preventing wear to these parts. Wearing rings are designed to be replaced periodically, limiting 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 BOB centrifugal water pump can be supplied with an external vacuum or electric priming pump. For longer suction distances, a vacuum priming pump would be more suited thanks to its ability to dry run for short periods of time.
