In this article, you will learn how to make a 12 volt water pump with your own hands. Such homemade products greatly facilitate the life of summer residents and private owners. Below we will consider a method for making a 12 volt centrifugal pump from lids, jars and syringes. If you have a 3D printer, you can print all the elements of the pump.

What you need to make a 12 volt pump from caps and a syringe
- 3 plastic jar lids of the same size
- Two/three syringes for 5 or 10 milliliters (depending on the size of the hoses and the required pressure)
- 12 volt motor (order from Aliexpress)
- glue gun
- Scissors
- Flexible ruler, marker
- soldering iron
- power unit
Making a 12 Volt centrifugal pump with your own hands
- Prepare materials and tools - wash, clean, dry.
- We cut off the top from one of the covers - only the frame should remain.
- In the other two, cut holes in the center. One hole is needed for the motor shaft, choose its dimensions yourself depending on your motor. Make a hole in the second cap for a syringe. Choose a syringe according to your needs - a 5 ml syringe is also suitable for spot irrigation. The size of the syringe also depends on the water supply hose.
- Glue a syringe, a tube for supplying water into the allotted hole.
- In a larger section of the cover, make a hole for the motor shaft. It should be slightly smaller than the diameter of the shaft so that the circle with the blades does not fly off it.
- Apply glue to the motor and insert its shaft into the hole made. The motor must be tightly and tightly connected to the body.
- From a 10/20 milliliter syringe, cut plates 1 cm high, 2-3 cm long. These will be the motor blades.
- Glue with a glue gun on the circle of the plate. They must be located in the fan/cooler, but must not touch the shaft.
- Remove the plastic ring under the cap from a regular bottle. Glue it to the fixed blades. This is to keep the blades together.
- Glue together the frame of the cover and the base (the part with the motor and the circle with the blades).
- Glue the cap with the water supply tube to the frame.
- In the side of the body, make a hole for the water outlet tube (syringe). Its dimensions depend on the thickness of the syringe and the hose to which you will connect the pump. To make it, use scissors or a soldering iron.
- Insert the syringe into the hole. Seal everything with a glue gun.
- Connect the wires of the motor to the power supply.
- Check pump operation.
How it works / how to use a homemade pump on 12 Volt
The power supply converts the mains voltage to 12 volts and supplies it to the motor. The motor shaft rotates, a circle with blades is tightly connected to it. The shaft rotates the circle, water flows through the feed syringe directly to the center. It fills the entire internal volume of the pump. The blades push it through the outlet tube into the high-pressure hose.
Additionally
You can make the same pump from a ready-made housing - watering nozzles. It is sold in every agricultural store. You will need to install the motor to the already finished circle with blades and connect it to the power supply. Such a design will be more reliable if properly manufactured.
You can also make a 12 Volt water pump by printing all its elements on a 3D printer - ready-made layouts are publicly available. With this manufacturing method, you need to choose high-quality plastic for printing.
