Скачать или смотреть How to Make a 775 DC Motor Powerful Water Pump | Full Episode

If you want to build a high-pressure water pump for your projects, a 775 DC motor can be a great choice due to its high torque and durability. In this guide, we’ll show you how to turn a 775 motor into a powerful DIY water pump for irrigation, aquarium use, or fluid transfer.

Materials Needed
✔ 775 DC Motor (12V/24V) – High-torque motor for strong pumping
✔ Centrifugal Pump Impeller – Or DIY alternative (plastic/metal blades)
✔ PVC Pipe & Fittings – For pump housing & water flow
✔ Shaft Coupler – To connect motor shaft to impeller
✔ Sealant (Epoxy/Silicone) – To prevent leaks
✔ Power Supply (12V Battery/SMPS) – Matches motor voltage
✔ Switch & Wires – For easy control
✔ Drill & Cutter – For modifications

Step-by-Step Build Process
1. Prepare the Pump Housing
Cut a PVC pipe (1-2 inch diameter) to make the pump chamber.

Attach inlet (bottom) and outlet (side/top) pipes.

Seal all joints with waterproof epoxy or silicone.

2. Attach the Impeller
Fix a centrifugal impeller (or DIY blades) inside the housing.

Connect it to the 775 motor shaft using a coupler.

Ensure smooth rotation without wobbling.

3. Waterproof the Motor
Cover the motor’s base with silicone sealant to prevent water damage.

Use a plastic cover if submersible pumping is needed.

4. Wiring & Power Supply
Connect the 775 motor to a 12V/24V power source.

Add an ON/OFF switch for control.

For higher speeds, use a PWM speed controller.

5. Testing & Optimization
Submerge the inlet in water and power ON.

Check water flow—adjust impeller or seal leaks if needed.

For more pressure, reduce outlet size or increase motor speed.

Why This Works?
✅ 775 Motor – Provides strong torque for pumping water efficiently.
✅ Centrifugal Force – Spinning impeller pushes water outward, creating flow.
✅ Adjustable Design – Can be modified for higher pressure or flow rate.

Upgrade Ideas
⚡ Use a Metal Impeller – For higher durability.
⚡ Add a Check Valve – Prevents backflow (see our DIY Check Valve Guide).
⚡ Battery-Powered – Make it portable with a 12V car battery.
