Options to purchase with your kit to suit this pump
Bore Caps are available with different size discharge threads. Your pipe and adaptor size is what will determine what size discharge thread it will need to connect with. Please keep this in mind when selecting your bore cap.
The splice kit is used to join the motor cable to the electrical drop cable. The splice kit makes a waterproof join.
A pump shroud is needed to cool the motor and is only required if you are installing a 4″ pump down 6″ or larger casing. A shroud adapter is also available on this site.
3 Phase Cable 3-wire/4 core submersible drop cable is required. However, you must check with your electrician on cable size. He will do volt drop calculations to meet site requirements to comply with AS.
