How To Make A Water Pump

Making water pumps is not an easy task. It needs a professional skill set that makes the water suck work flawlessly. However, water drives vary in kind and do not always need heavy mechanisms to make it. You need to understand its building mechanism and generate an idea of how to do it like any DIY project.

We shared some basic steps in the construction of a mini water pump at home in this article. You can use this as fun crafts or apply for light application. The most exciting part about a homemade water pump is, you can access all the necessary parts for this task in a nearby store.

You can use any motor depending on how much pressure you want in the drive. We worked on a small motor for a sample; you can choose a larger motor instead for better performance.

Powerful water pump Material

Here, we have listed the major parts and components for building a simple water pump design. For buying the components, you can check on an e-commerce website or any hobby stores nearby.

  • Motor. ( Choose your required one )
  • Plastic Candle Holder or Gatorade Bottle Cap.
  • Hot Glue
  • Plastic Food Containers

A simple water pump design 

Step 1 – Building The Impeller With Using Plastic Sheet

First of all, you will need to focus on the suck housing of simple water pump design. Take out the piece of plastic candle holder from the box. You can even use a Gatorade bottle cap as an alternative. The candle holder will be the simple pump housing of the motor.

Use a  sheet of plastic to make the bottom of the impeller. It can be anything similar to food packaging stuff. Remember to use a compass to trace out a circle on the plastic sheet, then cut it out. The process must be a little smaller than the simple pump housing opening hole. Water pump for drill a hole in the center of the sheet after installing it on the engine.

  • N.B – Try coloring the piece of plastic the circled so that it is highlighted enough.

Step 2 – Building the Impeller Blades With Piece Of Plastic

The second step is to make the impeller blades. Take a thin piece of plastic and cut four smaller pieces of it. These pieces will generally work as the impeller blades. Later on, take some hot glue; you can use a glue gun instead and stick the pieces on the cutout circled disk vertically.

Step 3 – Attaching the Motor for Powerful Water Pump

Here comes the vital part, fitting the motor to the water driveshaft is a critical task indeed. Thus, if you were a little cautious when doing this, it would be best. Firstly, measure the diameter of the motor shaft and draw a circle on the holder. Drill a slightly larger hole in the center of the candle holder.

Use hot-glue to stick the motor to the bottom of the drive housing. Lastly, seal the holes correctly so that water can’t get out through them.

Step 4 – Attaching the Impeller

The task of attaching the motor to the simple water pump design for housing is finally done. Now you need to connect the impeller blades to the motor shaft. Use glue between the blades of the impeller and mount the motor to them. Once you are done, dry out the glue and rotate the finished impeller to check if it’s working just fine.

Step 5 – Closing Off the Housing

Remember the first step of drilling a hole on the plastic sheet you cut out in a circle shape? Yes, you need to put a straw in there before you seal off the suck housing. Well, not only on the piece of a plastic circle, you need to drill a circle on the housing water’s exit hole.

Stick the pipes tightly to the housing and sheet of plastic with hot glue. It will keep the water inside, reducing the chance of any leakage. Keep the impeller blades to a height that they can’t touch the front circle. Make the suck housing durable by sticking its front side hardly with glue. After this, you can take the water suck on a test.

Step 6 – First Test

Suck the water through the pipes while testing the pipe. Please make sure the pump is filled with water unless it won’t work perfectly. Using a larger motor can increase the performance of your water pump. Besides, you can lay the pump down horizontally for better performance.

Step 7 – Modifications

If you want to improve the water suck you made, you can use these simple tricks. Keep the pipes tangential so that the water won’t feel forced to leave perpendicularly to the housing. Cut out the pipes’ bottom section and spread the gaps on both sides. Then on the last part, glue tit to the pump housing again and test it.

Step 8 – The Final Check

Although the final test seems to function slightly better, a more comprehensive motor can probably give better results. Unlike yours, some pumps can have the water source at the same level as a pump. If you draw the water a few feet up, then those suck. That means more work for that.

Don’t compare your project to those pumps when you turn up your pump horizontal, not vertical. It creates more pressure to shot water out. So, avoid that to ensure better results.
