The Grundfos SQE3 Series Model B Borehole Pump are submersible borehole pumps that offer the same features as the SQ3 pumps, but are used with either a CU300 or CU301 control box - to regulate and maintain a constant water pressure. This system can ensure that constant pressure is maintained within the maximum pump performance level, despite varying degrees of water consumption. The borehole water pump is able to operate without the control unit but cannot offer all the safety features and alarms as when the pump is connected to it. The SQE3 single phase motor is available from 0.7Kw to 1.85Kw depending upon model choice, and its variable speed drive changes the speed to match the demand enabling the pump to maintain constant pressure.
