What is a Submersible Water Pump?
A submersible water pump is a device with a sealed motor designed to operate while fully submerged in water.* Centrifugal forces are used to rotate impellers that then push water up to the surface. These pumps are commonly used to move water from wells, sumps, tanks, and even boats.
They’re ideal for managing dirty water, grey water, marine water, and more. Thanks to their sealed motor design, they can work underwater safely.

How Do I Choose the Right Submersible Pump?
Choosing the correct submersible pump depends on a few key factors:
- Type of Water: Are you pumping clean, grey, or dirty water? For muddy or debris-filled water, consider a pneumatic submersible water pump or a heavy-duty model built for dirty water.
- Application: For boreholes, a submersible well water pump is the best fit. For draining basements, a sump pump is recommended. If you’re off-grid, a submersible solar water pump is ideal.
- Power: Pumps are available with various kW ratings such as 0.75 kW and 1.1 kW and 2.2 kW. They require 220 – 230 V single-phase, or a 380 – 400 V three-phase power supply. Mini submersible pumps are often used with compact systems.
- Flow rate and Head Height: Ensure the pump can handle the volume of water you need at the required height.

Are Submersible Water Pumps Safe?
Yes, submersible pumps are designed with safety in mind. Since they are sealed and operate underwater, they reduce the risk of electrical hazards when properly installed.
Always follow manufacturer guidelines and ensure proper electrical protection for low-power DC pumps
Our technical team is experienced in the installation of submersible pumps for domestic and industrial use.
What Size Submersible Pump Do I Need?
Sizing depends on:
- Water volume to be moved
- Vertical distance (head height)
- Pipe diameter and flow requirements
For deep wells, a higher horsepower submersible well water pump may be necessary. For simple drainage, a smaller sump pump or mini submersible pump might suffice. Consult a pump specialist to ensure you get the right capacity.
