A submersible pump is designed to be completely immersed in the liquid it is pumping. This type of pump is commonly used to drain water from wells, tanks, ponds and swimming pools. The submersible pump works thanks to a hermetically sealed electric motor that drives an impeller, which creates a flow of water.

• Motor: The pump motor is sealed to prevent contact with water, thus preventing damage and short circuits.
• Impeller: The impeller is a rotating component that pushes water upwards and out of the pump through centrifugal force.
• Pump body: Contains the motor and impeller and is designed to withstand water pressure and corrosion.

Operation takes place in several stages:

1. Start-up: The pump is connected to the mains and the motor starts to turn.
2. Suction: The impeller creates a low-pressure zone by sucking water into the pump body.
3. Thrust: Centrifugal force pushes the water through the impeller towards the pump outlet.
4. Discharge: The water is expelled from the pump body through a discharge pipe.

Calculating the power of a submersible pump for a well requires several factors to be taken into account:

• Head: The vertical distance between the pump and the highest point where the water must be lifted.
• Flow rate: The amount of water that the pump must move in a given period (e.g. litres per minute).
• Pump efficiency: Generally expressed as a percentage value.

The formula for calculating power is:

Power = Flow rate × Head / Efficiency × 102

Where:

• Flow rate is measured in litres per minute (L/min).
• Head is measured in metres (m).
• Efficiency is a percentage converted to a decimal (e.g. 60% = 0.60).

Example:

If a pump has to lift 50 L/min to a head of 20 metres with an efficiency of 60%, the power required will be:

Power = 50 × 20 / 0.60 × 102 = 16.34W

The efficiency of a pump, also known as efficiency, indicates how well the pump converts energy into useful work to move the liquid. It is calculated by dividing the hydraulic power by the electrical power absorbed and multiplying the result by 100 to obtain a percentage.

The formula is:

Efficiency (%) = (Hydraulic power / Electrical power absorbed) × 100

Where:

• Hydraulic power is given by the product of flow rate, head and water density divided by 102 (a conversion factor).
• The electrical power absorbed is the power consumed by the pump.

Example:

If a pump has a hydraulic power of 1500 W and consumes 2000 W of electrical energy, the efficiency will be:

Efficiency (%) = (1500 / 2000) × 100 = 75%

A submersible pump with a power of 1 Hp (horsepower) absorbs approximately 0.746 kilowatts (kW) of electrical power. This value may vary slightly depending on the efficiency of the pump motor.

• Absorption: 1 HP = 0.746 kW.
• Consumption: Energy consumption depends on the operating time. If the pump runs continuously for one hour, it will consume 0.746 kWh.

Example:

If the pump runs for 10 hours a day, the daily consumption will be:

0.746 kW × 10 hours = 7.46 kWh

If the cost of electricity is 0.20 £/kWh, the daily cost will be:

7.46 kWh × 0.20 £/kWh = 1.49

The head of a pump represents the maximum height to which the pump can lift a liquid. A head of 30 metres means that the pump is capable of pushing water up to a height of 30 metres above the level of the pump itself. This value is crucial in determining the suitability of the pump for specific applications such as irrigation or lifting water from deep wells.

• Static head: The vertical height between the water level and the discharge point.
• Dynamic head: Also includes pressure losses due to friction in curved pipes and valves.

A head of 30 metres implies that:

• The pump can lift water to a vertical distance of 30 metres without considering pressure losses.
• If there are long or curved pipes, the actual capacity may be lower.

Protecting a submersible pump is essential to ensure its longevity and proper functioning. Here are some methods for protecting a submersible pump:

• Suction filter: Install a filter to prevent debris and particles from entering the pump and causing damage to the impeller and motor.
• Thermal protection: Use devices that shut down the pump in case of overheating to prevent damage to the motor.
• Float switches: Use switches that automatically shut off the pump if the water level drops too low, preventing dry running.
• Regular maintenance: Inspect and clean the pump periodically to remove debris build-up and check that the mechanical parts are working properly.
• Correct installation: Ensure that the pump is installed correctly and is not subject to excessive vibration or movement.

Identifying a burnt-out submersible pump is important to prevent further damage and costs. Here are some signs that a pump may be burnt out:

• No noise: If the pump does not make any noise when it is turned on, there may be an electrical problem or the motor may be burnt out.
• Circuit breaker trips: If the circuit breaker trips repeatedly, it could indicate an internal short circuit in the motor.
• Burning smell: A burning smell coming from the pump suggests that the motor has overheated and may be burnt out.
• Overheating: If the pump is excessively hot to the touch, this may indicate a motor malfunction.
• Low or no water flow: If the pump is unable to lift water or the flow rate is very low, the motor may be damaged.

Several factors can cause a submersible pump to malfunction. Here are some common causes:

• Electrical problems: Check that the pump is properly connected to the mains and that there are no tripped switches or blown fuses.
• Clogging: Check that the pump and pipes are not clogged by debris or sediment.
• Water level: Ensure that the water level is sufficient for the pump to operate and that the float switch is working properly.
• Mechanical faults: Check for damaged mechanical parts, such as the impeller or bearings.
• Thermal protective activation: If the thermal protective device has tripped, wait for the pump to cool down and reset the protective device.

When a well pump does not start, there can be various reasons behind the problem. Here are some common causes:

• Power supply: Check that the pump is properly connected to the mains and that there are no tripped switches or blown fuses. Also check that the power cable is not damaged.
• Float switch: If the pump uses a float switch, ensure that it is in the correct position and working properly. A faulty switch may prevent the pump from starting.
• Blocked motor: The pump motor may be blocked due to debris or sedimentation. A visual inspection and cleaning may resolve the issue.
• Control issues: Check the control system components, such as relays and control panels. A faulty component may prevent the pump from starting.
• Mechanical failures: Internal problems, such as damaged bearings or a blocked impeller, may prevent the pump from operating.

If a submersible pump stays on all the time, it could be a sign of several problems. Here are some possible causes:

• Stuck float switch: If the float switch is stuck in the 'on' position, the pump will continue to run. Check that the float moves freely.
• Leaks in the system: Leaks in the pipes or connections can cause a continuous cycle of filling and emptying, keeping the pump running.
• Faulty non-return valve: A malfunctioning non-return valve can cause water to flow back into the well, causing the pump to switch on repeatedly.
• Faulty pressure regulator: If the pressure regulator is not working properly, it may not switch off the pump as it should.
• Electrical problems: Short circuits or problems in the electrical circuit can cause the pump to run continuously. Check the electrical connections and switches.
