Instructions for installing the pump into the well with your own hands

Even before the purchase of such a pump, you should consider whether the dimensions of its housing correspond to the diameter of the well pipes. After all, it is clear that the diameter of the joints decreases somewhat. Moreover, the pump should not be "pushed" into the pipe, it should easily "pass through".If this issue is resolved, then it is possible to start installing the pump into the well, which is quite possible to do by one's own hands.

Reminder. Submersible pumps for wells work underwater. Therefore, the issues of reliable waterproofing of all joints should be constantly in the center of attention.

Preparation phase

First, an adapter( nipple) is installed on the pump outlet, since pipes will need to be connected to the pump. The nipple provides a transition from the internal to the external thread. Most pumps have an output diameter per inch and a quarter, although some models have an inch output. When purchasing, it should be asked if the adapter is included in the pump kit. If not, you should immediately buy it.

It is quite natural that any threaded connection requiring tightness is not done without "rewinding" at the junction. Plumbers are increasingly using the so-called FUM tape, although sometimes they use the patch. Specialists do not recommend using these winding materials when installing downhole pumps.




It is better to use Tangit tape or linen. If the latter is applied from above, it is coated with a silicone sealant or similar lubricant. Such materials will ensure the reliability of the connection. After all, in addition to the pressure acting on the joints, the entire assembly will also experience hydraulic shocks, the tube beating when the pump is running. A coupling is wound on the nipple.

When installing the pump, pipes can be used, not only metal, but also polypropylene pipes, the welding of which I have already told. In any case, it is recommended to use pipes with a diameter of at least 32 mm. Pipes that are more "shallow" will severely limit the pressure of water. Starting from the end of the pipe to be connected to the pump, it is maximally leveled( no less than 4-5 m).This is necessary so that when the pump is submerged in the well, it enters as smoothly as possible, without distortion. After this, the pump and pipe are connected.

The power cable that provides power to the pump motor is not necessarily included in the kit. Therefore, in the absence of it, it is necessary to connect the pre-prepared cable to the electrical terminals of the motor( to the output cable section).In this case, it is recommended to use shrink tubes, and from above to put a shrink sleeve. Such a connection will provide a reliable waterproofing. After carrying out this part of the work, the cable is laid along the pipe.

 To lower the pump into the well, a metal cable is required. It must be securely attached to the pump casing. Each model has for this purpose special mounting lugs. The cable is also laid along the existing route( cable, pipe).

The result is a path consisting of three elements. These "elements"( pipe, cable and rope) must be fixed to each other so that the whole can be obtained. For this, special clamps( metal, plastic), electrical tape, wire( but only with insulation, so as not to cut the cable and polyethylene pipe) are used.

Note. Such a connection should not be too dense.

Installation of the

pump After this preparation, the headband is put on the pipe. Do not forget to install the O-ring. After this, the pump is lowered into the pipe. If he is somewhere to cling, then he needs to "help" with rotational movements.

Given that the pumps come from different manufacturers, different models and modifications, it is necessary to carefully study the instructions attached to it before installing the pump in the well. I told you about the general order of work, which is relevant for any downhole pump, without taking into account the design features of a particular model.
