Submersible Pumps are advantageous. The installation is easy than comparing to the other pump. But many find it very hard. So, if you are searching for a proper guide on how to install a Submersible Pump in a lake. Then this article is for you.
Submersible pumps are easy to install. You have to understand the whole process and have to do all the steps correctly. Here we will show you 9 very simple and easy steps.
How to Install a Submersible Pump in a lake
Step 1: Inspect the lake
This is the first step in how to install a submersible pump in a lake. At first, inspect the lake, check the depth and water level. Checking the depth, consider both the distance from the water level to the bottom and the distance from the bottom to the ground of the lake because the pump will completely submerge under the water.
Then check the internal damages of the lake and repair it. You can do it own self.
Step 2: Inspect the supplied instruments
Now, if you have all your instruments, check all of the details. Check the power supply rating. Then identify if the motor is 2-wire single-phase or 3-wire single-phase or needs a starter or 3-phase configuration.
After that, check that the submersible pump drop cable suits the motor cable. And the motor is correctly rated for submersion in water. The bore cap needs to match with that, so inspect that too. Now check that the fittings match the outlet on the pump and the rising main.
Step 3: Set the motor to the pump
Fixing the motor use only supplied grease. Using a torque arrestor, take your time and fit the motor perfectly to the pump. This will help you protect your wires.
During the assembly, the process seal splined the shaft right there. When screwing into the pump, lay flat fitting or poly pipe with tape.
Step 4: Join your motor cable to the drop cable
The drop cable should be connected or spliced to the motor. Then ensure if it is watertight. Sometimes, the splice is made commercially or by heat shrinking the splicing kit. At this point, you just need to follow the instructions supplied with the kit.
Step 5: Assemble the pump next to your lake
Not assembling the pump next to your lake will be a little mistake that most people do. You can misplace some parts if you don’t do this. So, make sure you assemble the pump properly for long-lasting use. Then fit the rising main to the pump. Fit the bore cap to the other side of the rising main.
Step 6: Roll out the rising main and drop cable
Be sure that the safety cable is made of stainless steel. Then attach the safety cable to the pump and roll out with drop cable and rising main. It is also important to attach a safety cable to the end of the bore cap hence, diving stretching room to the rising main.
Step 7: Join your rising main with the drop cable
Use 4-6 turns of grey duct tape for every 4–6 meter apart to attach the drop cable to the rising main. Use some zip ties if you want. For stretching, allow some slack for the rising main. To protect it, tape the full length of the cable splice to the rising main, which is also expert advice.
In the future, the cable splice or motor may need replacement. So, tape a couple of extra drop cable meters below the bore cap. This is the most necessary step on how to install a submersible pump in a lake.
Step 8: Check the cables are fitting tight and secure
If the weight of the assembly of all products is light and if you feel you can lower the assembly. Then gently, lower the pump end into the lake. Take an assistant and tell him to hold the bore cap end. Pay close attention when you are lowering assembly because your electric drop cable and bore cap should not damage in any way.
Both of this cable is important. In the end, the assembly should be suspended on the top of the casing by the bore cap. For doing this step properly, you have to be patient and careful. You can not rush. If you want a quit, a long-lasting submersible pump stays calm and have patience.
Step 9: Use a car wheel to make a roller and lower the assembly if the weight is heavy
Now, if the weight is heavy, don’t do it own self; instead, use the car wheel to make a roller and lower the assembly.
At first, attach the bore cap to the vehicle with a “D” shackle and a sling. Then position the roller right over your lake. After that, position your vehicle to allow the pump to be lowered into the lake safely.
Start driving the vehicle towards the lake and make sure there are no damages. Lower the last two meters by hand will be good. Do it if possible. Lowering assembly is a very important step, so do it patiently and properly. In the very end, connect the pump protection, pump controller, and pump starter device tp your power supply.
Switch the current on and allow a few moments for the water to reach its surface. Finally, test the pump control and pump protection device. Now, you have the proper guidance on how to install a submersible pump in a lake.
