The Azcue MN VP/EP Centrifugal Self Priming Pumps is essentially the MN close coupled centrifugal pump complete with either a vacuum or electric priming pump for applications that involve more difficult suction conditions. For longer suction distances, a vacuum priming pump would be the better solution thanks to its ability to dry run for short periods of time.

The MN is a robust horizontal centrifugal pump with good flow and pressure capabilities, popular for the transfer of relatively clean fluids such as water and thin fuels. Based on DIN 24255, this model is dimensionally the same as other pumps allowing it to easily replace existing single stage centrifugal pumps from other manufacturers

The Azcue MN self priming centrifugal pump benefits from a back pull out design, allowing the motor to be removed without disconnecting the pump from the pipework, saving time during maintenance. Whilst being closed coupled, this centrifugal water pump has a lantern bracket, which means that whilst being of more compact construction, there is still space between the pump and motor so should the seal fail fluid will not enter the motor.

With separate shafts in the pump head and motor, these Azcue pumps have the benefit that if there is ever an issue with one shaft, there is no need to replace it all, unlike alternatives that have one continuous shaft from head to motor. This model also has wear rings, which means there is small clearance between the impeller and pump casing stopping these parts from wear. Wearing rings are designed to be replaced periodically, preventing the more costly replacement of the impeller or casing.

Castle Pumps' range is so vast that it includes pumps that other distributors do not have access to. For example, in this case study the client had approached other suppliers who were unable to fulfil their requirement of a self priming centrifugal pump able to handle flow rates of up to 8,300 l/min. Castle Pumps however were able to find the customer a solution.
