Residential areas which depend on ground water usage need an efficient source of pumping and a submersible pump can prove to be of great help in driving water to your home.
However, to ensure max results, you will have to select a right capacity submersible pump. It is most important for you to make the right selection, installation and then the maintenance. If the pump doesn’t install properly, it may cause the pump to fail prematurely.
So, here is a short guide by Pumpkart on how the whole apparatus to be installed.
For installing a submersible pump properly, the various steps need to be pursued. Follow the every instruction, so that it can ensure noise free and highly efficient performance in the long run.
Motor filing:
It is important to note that the motor of the pump is to be kept vertical. Usually a water filling plug is affixed at the top of the pump casting in order for it to prime easily. Make sure the water is oil free and sand free before pouring it into the plug hole. Start moving the motor to and fro gently and leave for 10-15 minutes. Make sure that the plug holes are open so that any air entering the procedure during winding will escape. Pour more water to the loss of volume caused as a result of air bubbles escaping through it. Now, screw up the two plugs precisely and check the motor thoroughly before installation. The motor is now all set to be coupled to the pump.
Cable connection:
It is advisable to connect additional cable to the cable supplied with pump. The selection of the cable should be made keeping in mind the actual requirements of your pump. To make a selection for the right cable diameter, you should have an idea about the expected voltage of the motor, expected power of the motor and supply cable total length.
In order to connect the additional cable to the pump cable, cut the cable and strip both ends of the cable to make a strong connection. Make sure the colors of the cables which are to be joined are identical.
Now, insert the bottom plug and a plastic tube in the pump cable. The top plastic plug should be affixed to the jointing cable. Join the cables and fasten them properly. Make sure after when you join the cable approx. 15 mm of whole covering lies within the interior of the cable splicing sheath on each side. After affixing the cables, file off the sharp corners properly and apply rubber and adhesive tapes to at least 2” across the junction.
Push the plastic tube over the joints and make sure it is central. Lid the bottom plug and insert it into the bottom of the tube. Now, twist the tape firmly around the bottom end of the tube and plug. Make sure to press it strongly for a perfect seal.
Suspend the joint vertically in such a way so that the bottom end of the tube points in the downward direction. Heat the tar based mixture in a small tin and pour the same compound in the tube from the top end. Refill the hollow space to make sure there is no shrinkage and allow the mixture to cool. Now, slide the top plug down the pump cable and push it steadily inside the top side of the tube. Wind the adhesive tape tightly over the top plug and pipe tube.
