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, 40 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.
