• Type of water to be managed: Determine whether the pump will be used for clean water (clear water) dirty water with debris (dirty water) or both.
• Depth of the well or basin: Assess the depth from which the pump will draw water, especially for deep wells.
• Amount of water to be moved: Consider the maximum required flow rate per hour in litres per hour (L/h) to ensure that the pump can handle the required volume of water.
• Pumping height: Check the maximum head, i.e. the maximum height to which the pump can push water, which is important for applications that require lifting water.
• Power supply: Decide whether you prefer a battery-powered pump for greater mobility or a mains-connected pump for continuous operation.
• Space available for installation: Evaluate the size and configuration of the pump based on the available space and easy installation.
• Materials and strength: Consider pumps with stainless steel coating if you require increased corrosion resistance and durability in harsh environments.

A submersible pump is designed to be completely immersed in the liquid to be pumped. This type of pump is commonly used to drain water from wells, tanks, ponds and swimming pools. The submersible pump is operated by a hermetically sealed electric engine driving an impeller which creates a water flow.

• Engine: The pump engine is sealed to prevent contact with water, thereby preventing damage and short circuits.
• Impeller: The impeller is a rotating component that forces water up and out of the pump through centrifugal force.
• Pump body: It contains the engine and impeller and is designed to resist water pressure and corrosion.

Operation takes place in several stages:

1. Ignition: The pump is connected to the mains and the motor starts to turn.
2. Suction: The impeller creates a low-pressure zone by drawing water into the pump body.
3. Thrust: Centrifugal force pushes water through the impeller towards the pump outlet.
4. Exhaust: Water is expelled from the pump body through a drain tube.

Calculating the power of a submersible pump for wells requires considering several factors:

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

The formula for calculating the power is:

Power = Flow rate × Head / Efficiency × 102

Where:

• The flow rate is measured in litres per minute (L/min).
• The head is measured in meters (m).
• Efficiency is a percentage converted to a decimal (e.g. 60% = 0.60).

Example:

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

Power = 50 × 20 / 0.60 × 102 = 16.34W

The performance 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 input and multiplying the result by 100 to obtain a percentage.

The formula is:

Efficiency (%) = (hydraulic power / electrical power consumption) × 100

Where:

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

Example:

If a pump has a hydraulic power of 1500 W and consumes 2000 W of electrical power, 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: The power 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 electricity cost is €0.20/kWh the daily cost will be:

7.46 kWh × €0.20/kWh = €1.49

The head of a pump is the maximum height at which the pump can lift a liquid. A head of 30 meters means that the pump is able to push water up to a height of 30 meters above the pump level. This value is crucial for determining the suitability of the pump for specific applications such as irrigation or lifting water from deep wells.

• Static prevalence: The vertical height between the water level and the drain point.
• Dynamic prevalence: It also includes pressure losses due to friction in curved pipes and valves.

A head of 30 metres implies that:

• The pump can lift water up to a vertical distance of 30 meters without considering load losses.
• If there are long or curved lines, the actual capacity may be less.

Protecting a submersible pump is essential to ensure its long service life and proper operation. Here are some methods for protecting a submersible pump:

• Suction filter: Install a filter to prevent debris and particles from entering the pump, causing damage to the impeller and engine.
• Thermal protection: Use devices that shut down the pump in the event of overheating to prevent damage to the engine.
• Float switches: Use switches that automatically shut off the pump if the water level drops too low to prevent dry running.
• Regular maintenance: Inspect and clean the pump periodically to remove debris buildup and check for proper operation of mechanical parts.
• Correct installation: Make sure that the pump is installed correctly and not subjected 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 might be burnt out:

• No noise: If the pump makes no sound when it is switched 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 engine.
• Burning smell: A burning smell from the pump suggests that the engine has overheated and may have burned.
• Overheating: If the pump is too hot to the touch, it may indicate a malfunction of the engine.
• Low or no water flow: If the pump cannot lift water or the flow rate is very low, the motor may be damaged.

Several factors can cause a submersible pump to fail. Some common causes include:

• 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 pump operation and that the float switch is functioning properly.
• Mechanical failures: Check for damaged mechanical parts, such as the impeller or bearings.
• Thermal protection activated: If the thermal protection has triggered, wait for the pump to cool down and reset the protection device.

When a well pump does not start, there can be several reasons behind the problem. Some common causes include:

• Electric 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, make sure it is in the correct position and functioning. A faulty switch could prevent the pump from switching on.
• Engine blocked: The pump motor may be blocked due to debris or sedimentation. A visual inspection and cleaning may solve the problem.
• Control problems: Check control system components such as relays and control panels. A defective component can prevent the pump from starting.
• Mechanical failures: Internal problems, such as damaged bearings or a blocked impeller, can prevent the pump from operating.

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

• Float switch locked: If the float switch is locked 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 filling and emptying cycle, keeping the pump running.
• Defective non-return valve: A malfunctioning non-return valve can cause water to flow back into the well, causing the pump to turn on repeatedly.
• Defective 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.
