The Azcue CM VP/EP ATEX Self Priming Vertical Inline Pump is the CM close coupled vertical centrifugal pump with incorporated vacuum or electric priming pump, intended for use where suction conditions may be difficult. The vacuum priming pump should be chosen for longer distances, as this version can dry run for short periods of time.

The CM ATEX rated vertical centrifugal pump is larger and more robust than the LN, with greater capabilities for flow and pressure. This pump range is perfect for applications concerning relatively clean liquids such as water and thin fuels, and where space saving is important. Similar to the VR single stage centrifugal pump but with the addition of a ball bearing between the pump and motor for sharing strain of operation, and a spacer coupling to eliminate the removal of the motor first when maintenance of the pump is undertaken.

The Azcue CM vertical self priming centrifugal pump has a back pull out design so that the motor can be removed without the need to completely disconnect the pump from its installation, something which saves a lot of time when it comes to maintenance. Technically speaking this pump is close coupled; however these centrifugal water pumps have a lantern bracket which creates space between the pump and motor, whilst still being compact. With this design feature no fluid will fall into the motor if the seal fails.

These Azcue ATEX vertical inline pumps have a shaft in the motor and another in the pump head, so that if there is an issue with one, there’s no need to replace it – a beneficial feature which other alternative pumps on the market lack, as they have one continuous shaft from head to motor. A further advantage of this pump is its wearing rings, and the small space between the impeller and pump casing which prevents wear to these parts. These wearing rings can be replaced periodically, and prevent the costly replacement of the impeller or casing.
