The Azcue CM Self Priming Vertical Inline Pump is the CM close coupled vertical centrifugal pump with integrated vacuum or electric priming pump, designed for where suction conditions may be difficult. For longer distances, the vacuum priming pump should be selected thanks to its ability to dry run for short periods of time.

The CM is a larger, more robust vertical centrifugal pump, with larger flow and pressure capabilities than the LN. They are ideal solutions for applications involving relatively clean liquids such as water and thin fuels, where space saving may be important. It is same as the VR single stage centrifugal pump with the additional ball bearing between the pump and motor to share the strain of operation, but with the further addition of a spacer coupling for maintenance of the pump without having to remove the motor first.

The Azcue CM vertical self priming centrifugal pump is a back pull out pump, meaning that the motor is able to be removed without having to completely disconnect the pump from the installation, saving time 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 fails, no fluid will fall into the motor. 

These Azcue vertical inline pumps have one shaft in the pump head and another in the motor meaning that if one there is ever an issue with one, there is no need to replace it all; a benefit over other alternative pumps on the market that have one continuous shaft from head to motor. Thanks to their wearing rings, there is small clearance between the impeller and pump casing preventing wear to these parts. Wearing rings are designed to be replaced periodically, preventing the more costly replacement of the impeller or casing.
