The Azcue VM & VR ATEX Vertical Inline Pumps are large, heavy duty vertical centrifugal pumps, with large flow and pressure abilities compared to those of the LN range. Ideal for applications concerning relatively clean liquids like water and thin fuels, these ATEX pumps are also great for applications where space saving is important. Dissimilar to the VM, the VR single stage centrifugal pump benefits from an additional ball bearing between the pump and motor which results in a share in the strain of operation, making it more robust than the VM.

The Azcue VM/VR vertical inline centrifugal pump is a back pull out model, meaning the motor can be removed from the pump without the need to disconnect the pump from its installation completely; a time saving benefit when it comes to maintenance. These centrifugal water pumps are technically close coupled, but thanks to its lantern bracket, space is provided between the pump and motor whilst still being compact – meaning if the seal wears, no fluid will fall into the motor. Small clearance between the impeller and pump casing is due to this model’s wear rings and ensures the parts aren’t subjected to wear. Designed to be replaced periodically, wearing rings prevent the costly replacement of the impeller or casing.

These Azcue vertical inline pumps have separate shafts in the pump head and motor, so that if there’s an issue with one shaft, there is no need to replace it all – an advantage which other pumps in the market don’t benefit from as they have one continuous shaft from head to motor. The VM and VR ATEX close coupled centrifugal pumps are available with an external vacuum or electric priming pump. Where suction conditions are more difficult, versions with a vacuum priming pump should be chosen due to its ability to dry run for short periods of time.

Features of the VM/VR Vertical Inline Pump:

  • Close coupled, single stage vertical centrifugal pump

Ballast Water System Upgrade - Vertical Inline Centrifugal Pumps

Ballast Water System Upgrade - Vertical Inline Centrifugal Pumps

Castle Pumps received an enquiry from a new customer who needed to upgrade their ballast water system, in order to meet the 'Ballast Water Management Convention 2017' regulation. We supplied Azcue cast bronze pumps to ensure that all wetted parts that come into contact with the seawater are non-ferrous and therefore would not corrode.

Ballast Water Transfer for Vessel - Vertical Inline Pump

Castle Pumps have built solid relationships with many industrial pump manufacturers, which gives us confidence in our ability to meet tight project time scales. This case study illustrates this, where we were able to get two ballast pumps manufactured and marine certified in three weeks less than the industry standard lead time.

The VM & VR Vertical Inline Centrifugal Pump is manufactured by Azcue Pumps, for whom Castle Pumps are the UK agent. 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 VM & VR vertical inline 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 VM & VR vertical centrifugal pumps 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 motor being located above the pump head, makes the Azcue VR & VM vertical inline pump suited to applications where installation space may be limited including:

Marine Applications:Industrial Applications:
  • Sea water cooling pump
  • General sea water service
  • Grey water with low solid content
  • Aquaculture recirculation systems
  • Marine ballast pump
  • Low viscosity fuel and lubrication transfer
  • Boiler feed pump
  • Closed loop HVAC circulating and cooling pumps
  • General water transfer, supply and service
  • Waste water with low solid content
  • Water pressure booster pump
  • Swimming pool recirculation systems
  • Low viscosity fuel and lubrication transfer
  • Boiler feed pump
