Submersible water pumps are the hidden workhorses of many water systems, quietly operating below the surface in boreholes, wells, tanks, rivers, and sumps. Designed to run underwater, these pumps are highly efficient, reliable, and ideal for applications where water needs to be pushed up from depth rather than sucked from above. If you are planning a borehole, upgrading your water supply, or managing a commercial or agricultural site, understanding how submersible pumps work will help you choose, operate, and maintain them more effectively.

What is a submersible water pump?

A submersible water pump is a fully sealed pump-and-motor unit designed to operate while completely submerged in the liquid it is pumping. Unlike surface pumps that sit above the water and pull it up, a submersible pump sits down in the water source and pushes water upwards through a delivery pipe.

These pumps are commonly used for:

• Borehole and well water extraction

• Domestic and commercial water supply

• Irrigation and farm water systems

• Drainage, dewatering, and sump pumping

• Industrial and wastewater handling

Because the pump is below the water level, it never needs priming and is much less prone to problems like air locks and cavitation, which can affect surface-mounted pumps.

Key components of a submersible pump

While designs vary by brand and application, most submersible water pumps share a similar internal structure. Typical components include:

• Electric motor: A hermetically sealed motor, usually oil-filled or water-filled, that drives the pump. It is built to resist water ingress and operate continuously under pressure.

• Pump section (impellers and diffusers): A series of rotating impellers and stationary diffusers form the pumping stages. As water passes through each stage, its pressure and energy increase.

• Impeller: The impeller is a rotating disk with curved vanes. As it spins, it throws water outward using centrifugal force, converting motor energy into kinetic energy in the water.

• Diffuser: Surrounding each impeller, the diffuser slows the high-velocity water and converts kinetic energy into pressure, allowing the pump to push water to greater heights.

• Intake screen: This sits near the bottom of the pump and filters out large particles, helping to protect internal components from damage.

• Mechanical seal: A critical sealing element that prevents water from entering the motor section along the rotating shaft.

• Discharge outlet: The connection point where pressurized water exits the pump and enters the rising main or delivery pipe.

Each part is engineered to work together under water pressure, ensuring reliable performance even at significant depths.

How submersible water pumps work

The working principle of a submersible water pump is based on converting electrical energy into kinetic and then pressure energy within the water. The process is simple but very effective:

1. Power supply and motor activation
   An electrical cable from the surface supplies power to the sealed motor. When the pump is switched on—either manually, via a control panel, or automatically through a float switch or level sensor—the motor starts to rotate the shaft.

2. Impeller rotation and water intake
   The rotating shaft turns the impeller (or a series of impellers in multi-stage pumps). As the impeller spins, it creates a low-pressure region at its centre (the eye of the impeller). Water is drawn in through the intake screen to fill this low-pressure zone.

3. Water acceleration and energy transfer
   The impeller blades fling water outward at high speed due to centrifugal force. This action transfers energy from the motor to the water, increasing its velocity and kinetic energy.

4. Pressure build-up in the diffuser
   The high-velocity water then enters the diffuser, a stationary passage surrounding the impeller. The diffuser slows the water down, converting its velocity into pressure. In multi-stage pumps, this process is repeated through several impeller–diffuser pairs, each stage adding more pressure.

5. Water discharge to the surface
   The pressurised water flows into the discharge outlet and up through the delivery pipe towards the surface, storage tank, or distribution system. Because the pump is pushing from below, it can move water from much greater depths than most suction-based pumps.

The crucial difference is that submersible pumps push water rather than pull it. This eliminates the limitations of suction lift and greatly reduces issues caused by air leaks or long suction lines.

Benefits of submersible water pumps

Submersible water pumps offer several advantages that make them a preferred choice for boreholes, wells, and deep water sources:

• High efficiency: Working under positive pressure at the inlet, they require less energy to move water compared to pumps that must pull water up.

• No priming required: Since the pump is always submerged, there is no need to fill the suction line or pump housing with water before operation.

• Reduced cavitation: With the pump located in the water, the risk of cavitation (formation and collapse of vapour bubbles that can damage the pump) is significantly lower.

• Quiet operation: Installed deep in the water, submersible pumps are much quieter than surface pumps, enhancing comfort in residential and commercial environments.

• Space saving: With the pumping unit below ground or in the water body, there is minimal equipment clutter at the surface.

For homeowners, farmers, industries, and water project managers, these benefits translate into reliability, lower running costs, and longer equipment life when properly selected and maintained.

• Generator (Power Source): Converts fuel—diesel, petrol, or gas—into electricity via an engine-driven alternator. Output ranges from 3kW for small pumps to 20kW+ for industrial units, with surge capacity to handle pump startup loads.

• Electric Water Pump: The heart of the system, featuring an impeller, volute casing, shaft, and motor. Submersible models sit in boreholes or sumps; centrifugal surface pumps handle irrigation or drainage.​

• Control and Accessories: Includes fuel tank, voltage regulator, pressure switch, hoses, strainers, and safety features like low-oil shutdown. Wiring must match voltage (230V common in Kenya) to avoid overloads.​

Raeli Hydro pre-matches generators to pumps for optimal efficiency, ensuring your setup runs smoothly without voltage drops or overheating.

How Generator Powered Water Pumps Work

Fuel ignites in the generator engine, spinning the rotor to produce AC power that drives the pump motor. The motor rotates the impeller, creating centrifugal force to lift and push water through pipes—up to 100+ meters head for deep boreholes.​

Key mechanics:

• Startup Surge: Pumps draw 2–3x running amps; choose generators with 20–50% extra capacity (e.g., 5kW gen for 1HP pump).​

• Flow Rates: 5,000–50,000 liters/hour, depending on model—perfect for irrigating 1–10 acres or filling tanks fast.

• Runtime: 8–24 hours per tank, fuel-efficient at 0.5–2 liters/hour.

Multistage water pumps deliver high-pressure water efficiently, making them essential for applications like high-rise buildings, irrigation systems, and industrial processes. By Raeli Hydro. These pumps use multiple impellers on a single shaft to boost pressure stage by stage, outperforming single-stage models in demanding scenarios.

Core Components of Multistage Pumps

Multistage water pumps feature key parts that work in harmony for reliable performance.​

• Impellers: Rotating wheels that impart kinetic energy to water via centrifugal force; multiple impellers create sequential pressure boosts.

• Diffusers or Volutes: Channels that slow water velocity, converting it to static pressure before the next impeller.​​

• Pump Casing: Encloses components, directs flow from suction to discharge ports.​

• Shaft and Bearings: Driven by an electric motor, supported to handle rotational stress and axial thrust.​

• Seals: Prevent leaks around the shaft, ensuring efficiency and safety.​

Horizontal or vertical designs suit various installations, with vertical models ideal for space-constrained setups like boreholes.

Step-by-Step Operation Process

Multistage pumps operate on centrifugal principles, building pressure progressively across stages.

Water enters the suction port at low pressure, drawn into the first impeller’s eye (center). The motor spins the shaft at high speed (typically 1,450–3,500 RPM), flinging water outward through the impeller vanes. This adds velocity (kinetic energy).

The high-velocity water exits into a diffuser, where passages widen, slowing flow and converting velocity to pressure. Return channels guide pressurized water to the next impeller’s eye, repeating the cycle.​​

Each stage adds roughly equal pressure; a five-stage pump multiplies output fivefold versus a single stage. Final high-pressure water exits the discharge port, ready for elevation lifts or long-distance transfer.​

Balance mechanisms like wear rings minimize thrust on bearings, extending pump life.​

Types of Multistage Water Pumps

Choose based on orientation and application.

Vertical models excel in Nairobi’s urban water boosting needs, handling elevations over 100 meters efficiently.​

Advantages for High-Pressure Needs

Multistage designs shine where single-stage pumps falter.

• Higher Head: Achieve 200+ meters total dynamic head without excessive power draw.​

• Efficiency: Distribute workload evenly, reducing energy use by 20–30% versus oversized alternatives.​

• Compact Size: Generate boiler-feeding pressures (up to 100 bar) in smaller footprints.​

• Versatility: Handle clean water, light chemicals; flow rates 1–500 m³/h.​
