The Azcue VRX Vertical Immersion Pump is the immersed version of the VRX horizontal centrifugal pump, meaning that its motor is separated from the pump head, keeping it above liquid level. Supplied with a vortex impeller, this cantilever pump creates a vacuum so that large solids can pass through without interfering with the pump’s internals. This vertical line shaft pump is therefore ideal for applications involving waste water, slurries and viscous, contaminated liquids.
As the pump head is located within the fluid, vertically immersed pumps maintain a flooded suction. They are therefore ideal for applications where typically a self-priming pump is required, such as the emptying of tanks, reservoirs, sumps and wells require. This is why they are widely referred to as vertical sump pumps. As this series of Azcue pump is contained within the tank it is also well suited to applications where space saving is required or where if the pump was located outside the suction distance would be too long.
The immersed column of the VRX vertical cantilever pump is oil filled for mechanical seal cooling, allowing fluids up to 100°C to be handled. Vertical column pumps are a good alternative to submersible pumps for the handling of such high temperature fluids as not only are their seals located outside the fluid protecting them from degrading, they are not affected by the NPSH issues that can occur when pumping a liquid so close to its boiling point.
The bottom bearing lubrication enables dry running of the vertical shaft pump if the operator leaves it running once the container is empty, meaning that start-stop float switches are not required.

This customer was having daily issues with a pump brought from another supplier. The pump, which was transferring blood, water and feathers; was clogging every day, halting production and costing them £0000's in downtime. We decided to visit the site to get a greater understanding of the customer's requirements. From there, we came up with a pumping solution fit for purpose, which has been running for over 3 months (& counting) clog free.
Some of the enquiries we receive here at Castle Pumps are straight forward and give us all the information that we need to specify a pump. This fishery company enquired asking us for a specific type of pump and told us the exact fluid and contents that they'd be pumping. This information enabled us to proceed quickly with our recommendation and then onto the manufacture and supply of the pumps.
Castle Pumps have a wealth of experience supplying pumps to the marine industry, and we ensure that we match the features of the pump to the specific application at hand. This case study demonstrates this, as we knew that for guaranteed reliability for emptying a sump of sea water and waste solids, a pump with vortex non-clogging impellers would be required and the material would be best in bronze to avoid corrosion from the sea water.
The VRX Vertical Immersion 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 VRX vertically immersed 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 VRX cantilever 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.
The Azcue VRX Vertical Immersion Centrifugal Pump has a vortex impeller that creates a whirlpool/vacuum, which keeps any solids away from the impeller as the fluid is pulled through the pump to prevent damage to the internals. It’s minimal risk of clogging and solid handling capabilities make this single stage centrifugal pump ideal for dirty fluids containing solids in applications where the pump is better immersed into the fluid such as:
|Marine Applications:||Industrial Applications:|
- Black and grey water containing solids
- Contaminated bilge water pumps
- Fish waste pumping
- Waste slurries
- Waste water transfer containing solids
- Slurries and sludges
- Sewage pumping
- Organic waste e.g. food, manure and vegetation
