Motor
The pump is coupled to a sealed, liquid cooled 2-pole asynchronous squirrel-cage GRUNDFOS motor constructed of stainless steel. Single phase motors are supplied complete with purpose designed control boxes, while three phase motors require a remote Direct-on-Line starter. If unstable supply voltage is likely an additional quick tripping control relay is recommended.
Enclosure Class: IP58
Insulation Class: B
Speed: 2900rpm
Operating Conditions
Pumped Liquid: Thin, clean, chemically non-aggressive liquids without solid particles or fibres.
Max Liquid Temperature: +40°C.
Max Water Depth: Up to 1.5kW 1ph and 2.2kW 3ph – 150m, 2.2kW 1ph and 3kW 3ph – 600 m
Minimum Borehole Diameter: 110mm
Pumps are coupled to sealed canned type liquid cooled 2-pole asynchronous GRUNDFOS motors constructed of stainless steel. Motors require remote controllers, the DAYLIFF electronic controller, which provides full control against fluctuating power input as well as wireless low level control being recommended for smaller motors and the GRUNDFOS MP204, which provides additional protection from mechanical failure as well as advanced monitoring features for motors of 7.5kW and above. Note that due to the low starting torques of submersible motors Direct-on-Line starting is recommended for all motor sizes.
