The Azcue BOB 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.

The BOB 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 BOB 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 BOB 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 combined with its high flow capabilities, makes the Azcue BOB long coupled centrifugal pump suited to applications including:

Marine Applications:Industrial Applications:
  • Fresh water & sea water cooling pump for large vessels
  • General sea water service
  • Grey water with low solid content
  • Aquaculture recirculation systems
  • Ballast water pump
  • Fire fighting
  • Low viscosity fuel and lubrication transfer
  • Boiler feed water pumping
  • Marine fume scrubber systems
  • Closed loop large scale HVAC water circulating
  • Cooling pumps
  • General water transfer, supply and service
  • Waste water with low solid content
