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.

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

Solar submersible pumps are transforming how homes, farms, and institutions access water in off-grid and remote locations. By using the sun’s energy instead of grid electricity or diesel, they offer a cleaner, more reliable and cost‑effective solution for boreholes, wells and deep water sources. In this guide, Raeli Hydro explains how solar submersible pumps work, their key components, and why they are an ideal choice for modern water projects.

What is a solar submersible pump?

A solar submersible pump is a water pump designed to operate underwater, powered by electricity generated from solar panels. Instead of relying on mains power, the system uses sunlight to run an electric motor that drives the pump, pushing water from a borehole, well, river or storage tank to where it is needed.

Because the pump is installed below the water level, it is highly efficient at lifting water from deep sources. This makes solar submersible pumps especially suitable for:

• Domestic and rural water supply

• Irrigation and livestock watering

• Community water projects and schools

• Industrial and institutional boreholes

For clients working with Raeli Hydro, this technology offers long‑term savings on fuel and electricity bills while ensuring dependable water access, even in areas with poor grid connection.

Main components of a solar submersible pump system

A typical solar submersible pumping system consists of several integrated parts working together:

• Solar panels (PV modules): These capture sunlight and convert it into direct current (DC) electricity. The number and size of panels depend on the pump size, depth and daily water demand.

• Pump controller (or inverter): This smart device manages power flow from the panels to the pump. It optimises performance, protects the motor from low or high voltage, and can interface with level sensors in tanks or boreholes.

• Submersible pump: This is the unit installed underwater. It contains an electric motor and hydraulic section with impellers or a helical rotor to push water upwards.

• Cables, piping and fittings: Special waterproof cables carry power down to the pump, while pipes convey water to tanks, distribution lines or irrigation systems.

• Optional battery or water storage: In many designs, water is pumped into an elevated storage tank during the day, replacing the need for batteries. In some cases, battery backup is added for night or very cloudy conditions.

Raeli Hydro designs and sizes each component carefully so that the whole system works efficiently with local solar conditions and your specific water needs.

How do solar submersible pumps work?

While the technology behind solar submersible pumps is advanced, the working principle is straightforward. Here is a simple step‑by‑step overview:

1. Sunlight hits the solar panels
   During daylight, solar panels absorb energy from the sun’s rays. Inside each panel, photovoltaic (PV) cells convert this light into DC electricity.

2. Electricity flows to the controller
   The DC power from the panels is fed into the pump controller. The controller regulates voltage and current, ensuring the pump receives stable power. In systems with AC pumps, an inverter function converts DC to AC.

3. The submersible motor starts running
   Once there is enough power, the controller starts the submersible pump. The electric motor inside the pump converts electrical energy into mechanical energy, spinning an impeller or rotor.

4. Water is lifted to the surface
   As the impeller spins, it creates pressure that pushes water up through the rising main (delivery pipe). The water is delivered to a storage tank, header tank or directly into the distribution network or irrigation system.

5. Smart control and protection
   Many modern controllers include level sensors and dry‑run protection. If the water level in the borehole drops too low, or the tank becomes full, the controller automatically stops the pump to prevent damage and overflow. When sunshine returns and conditions are safe, the pump restarts.

The result is an automated system that pumps water whenever the sun is shining—without manual switching, fuel deliveries or complex maintenance.

Types of solar submersible pumps

Solar submersible pumps are available in different designs to suit various applications:

• DC solar submersible pumps: These connect directly to DC power from the panels via a controller. They are highly efficient and ideal for off‑grid systems.

• AC solar submersible pumps: These use an inverter to convert DC to AC, allowing the use of standard AC borehole pumps. This is useful where an existing pump needs to be converted to solar.

• Centrifugal submersible pumps: Use rotating impellers to move large volumes of water at moderate heads, suitable for shallow to medium‑depth boreholes and high‑flow applications like irrigation.

• Helical rotor (screw) submersible pumps: Use a helical screw inside a rubber stator, ideal for deep wells and high heads with lower flow. They are very efficient at lifting water from great depths.

Raeli Hydro helps clients choose the right pump type based on borehole depth, required flow rate, daily water demand and budget.

Key advantages of solar submersible pumps

Switching to solar submersible pumps delivers multiple technical and economic benefits:

• Lower operating costs: Once installed, the energy from the sun is free, drastically reducing or eliminating electricity and diesel expenses.

• Reliable in remote and off‑grid areas: Perfect for rural communities, farms and lodges far from the grid or suffering frequent blackouts.

• Minimal maintenance: With no fuel systems and fewer moving external parts, well‑designed solar pumps require less routine maintenance than generator‑powered systems.

• Environmentally friendly: Solar pumping reduces carbon emissions and noise pollution, supporting sustainable water supply solutions.

• Scalable and modular: Systems can be expanded by adding more panels or upgrading pumps as water demand grows.

For organisations prioritising sustainability and long‑term value, solar submersible pumps are a smart investment that pays back over time.
