Description
APPLICATIONS
Grundfos SP pumps are primarily used to pump raw water from underground. The pumps are installed in boreholes or wells submerged below water. They are also suitable for raw water supply, irrigation, ground water lowering, pressure boosting, fountain applications as well as mining.
CONSTRUCTION FEATURES
Energy optimized ErP ready stainless steel centrifugal submersible pump coupled to asynchronous two pole submersible motor made in AISI 304 stainless steel for parts in contact with water. Cooling and lubrication of the thrust bearing and carbon brushes is provided by a mixture of water and glycol.
OPERATING CONDITIONS
To ensure long and trouble free life, it is important the following are observed.
Electrical Protection
A suitably sized control panel incorporating a Grundfos MP204 controller should be fitted to protect the pump.
Minimum and Maximum Flow Rate
To ensure sufficient cooling of the motor, the pump must NOT run continuously at a flow rate below 0.1X nominal flow rate or above 1.3X nominal flow rate due to cavitation.
Pump Liquids: Clean, thin, non-aggressive liquids not containing solid particles of fibre larger than sand grains
Max. Sand content: 50ppm
Liquid temp: 40°C
Min. Borehole Diameter: 110m
Max. Install. depth below water: MS402 – 150m
MS4000 & above- 600m
