There are other accessories that you will need to install your bore pump which include bore cap, drop cable, support cable, riser pipe, pressure gauge, etc. These are listed below
Please be sure that your pump and accessory selection is correct before you purchase as the onus is on you. This is why I have included suggestions below with links, to ensure you select the correct size accessories for this model pump.
Options to purchase with your kit to suit this pump
A splice kit is used to join the electrical drop cable from the motor to your existing or new electrical drop cable. The join must be waterproof as it is submerged under the water. Many problems can occur if this join is not 100% waterproof. You can find the 4″ Splice Kits here.
This model has a 1 1/4 (32mm) discharge thread, so if you are using 32mm pipe diameter then a 1.25″ Bore Cap would be recommended.
A shroud adapter is only needed if you are installing a 4″ pump down 6″ or larger casing.
If using 32mm pipe diameter then a 32 x 100mm (1 1/4″ riser) PVC Shroud Adapter would be recommended.
The info below is a guide only, you must check with your electrician on cable size.
3 Phase Cable (3-wire/4 core) – 1.5mm sq cable up to 120m
Always check with your electrician. He will do volt drop calculations to meet site requirements to comply with AS.
