SUBMERSIBLE PUMP INSTALLATION

A correctly selected and installed submersible water pump in a properly constructed water well can be trouble free for many years. Here is how to go about installing a submersible water pump properly.
Inspect the well, looking for signs of external damage to casing, check the depth and standing water level:
Check the well total depth – the distance from the ground level to the bottom of the well. Head – A vertical distance from the pump to the ground level where water is discharged or into a pressure tank. GPM – the amount of water in GPM the pump produces.
Inspect the supplied components:
Check the details on the submersible motor looking for power supply rating, identify whether it is a 2-wire single phase, a 3-wire single phase and needs a pump starter box or 3 phase configuration. Check that the submersible pump drop cable suits the motor cable and motor and is correctly rated for submersion in water. Check that the fittings match the outlet on the pump, the rising main and the bore cap.
Fit motor to pump:
Use supplied grease to lubricate and seal splined shaft on assembly. Tape poly pipe or lay flat fitting with thread tape and screw into pump.
Splice drop cable to motor cable with supplied cable splice kit:
When the drop cable must be spliced or connected to the motor leads, it is necessary that the splice be water tight. The splice can be made with commercially available potting or heat shrink splicing kits. Follow the kit instructions carefully.
Lay pump assemble next to water well:
Fit rising main to pump and roll out. Fit bore cap to the other end of rising main.
Connect pump starter, pump controller and pump protection device to power supply and test pump. Allow a few moments for the water to reach the surface.
On completion of the initial test proceed to connect the required pipe work to the bore cap. Finally test pump operation and operation of pump protection devices and controls.
