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:
This model has a 2″ (50mm) discharge thread, so if you are using 50mm pipe diameter then a 2″ Bore Cap would be recommended. If you are using a 1.5″(40mm) pipe diameter then a 1.5″ 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 50mm pipe diameter then a 50 x 100mm (2″ riser) PVC Shroud Adapter would be recommended.
The info below is a guide only, you must check with your electrician on cable size.
3-wire 4-core cable selection: 1.5mm sq cable for up to 69m, 2.5mm sq cable for up to 114m, 4mm sq cable for up to 182m.
Always check with your electrician. He will do volt drop calculations to meet site requirements to comply with AS.
Starter / Contactor
The 3 Phase contactor for this model is a 3kw starter/contactor.
Bore pump wet ends are universal which means they can be fitted to other brand 4? motor. If you would like a Franklin Motor instead of a Wilo, just ask and we can arrange this for you.
