The Grundfos SQE5 Series Model B Borehole Pump is used for the same applications and conditions as the SQ5 deep well pump but is able to maintain constant pressure and is easy to operate and maintain. These borehole water pumps can be supplied with either a CU300 or CU301 control box which offers intelligent control, allowing the pump to slow down or speed up depending on your application needs, whilst continuing to maintain constant water pressure. A high quality stainless steel pressure censor sends a signal to the control box which will then command the pump to start, stop, speed up or slow down in order that the pressure is kept at a constant.
