The Azcue VM & VR VP/EP Self Priming Vertical Inline Pumps are essentially the VM & VR close coupled vertical centrifugal pumps complete with a vacuum or electric priming pump for applications it more difficult suction conditions. For longer distances, a vacuum priming pump should be picked thanks to its ability to dry run for short periods of time.

The VM & VR vertical inline centrifugal pumps are larger, heavier duty alternatives to the LN with larger flow and pressure capabilities. They are ideal solutions for applications involving relatively clean liquids such as water and thin fuels, where space saving may be important. Unlike the VM, the VR single stage centrifugal pump has an additional ball bearing between the pump and motor to share the strain of operation, making it the more robust of the two within critical applications.

The Azcue VM/VR vertical self priming centrifugal pumps are back pull out models, which means that the motor is able to be removed from the pump without having to completely disconnect the pump from the installation; a great time saving benefit during maintenance. Although technically close coupled, these centrifugal water pumps have a lantern bracket that provides space between the pump and motor whilst still being compact. This means that if the seal wears, no fluid will fall into the motor. 

These Azcue vertical inline pumps have separate shafts in the pump head and motor meaning that if one 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. Thanks to its wear rings, there is small clearance between the impeller and pump casing subjecting these parts to less wear. Wearing rings are designed to be replaced periodically, preventing the more costly replacement of the impeller or casing.

Ballast Water System Upgrade

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.

Fleet Management

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.
