Maximum flow and maximum head are separate operating points and are not delivered simultaneously. Select the pump against the required flow and total dynamic head, including the pumping water level, elevation, required outlet pressure and pipework losses. Match the pumping rate to the sustainable borehole yield.

What is included

  • Version 1: pump, motor and control box.
  • Version 2: pump, motor, control box, baseplate, 80 m cable, cable joint and rope. The cable length is specified for this kit; confirm the rope length when planning the installation.

Select the required kit version where options are offered. Delivery pipework, valves, separate water-level controls and installation labour are additional unless specified in your quotation.

Installation and protection

Use a qualified installer for cable sizing, electrical protection, earthing and commissioning. Provide suitable water-level and dry-run protection; the supplied start box should not be assumed to provide dry-run protection. Keep the motor suitably submerged and cooled. The manufacturer advises the Version 1 kit with separately sized cable where longer cable runs are required; do not assume that the Version 2 cable is suitable for your installation.
