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 that is axially displaced from the suction, this cantilever pump creates a vacuum so that large solids almost up to the inlet/outlet size 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. When running at a low rpm, the Azcue VRX can be used to transfer live fish without damage

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.

FAQs

Otherwise known as a vertical column pump, this is where there is an elongated shaft to separate the motor above the fluid from the pump that is immersed in the fluid.
