Borehole Submersible Water Pump for Irrigation and Water Supply

A Solution for Deep Groundwater

When the groundwater level is beyond the suction capability of an above-ground pump, the submersible unit can be lowered directly into the well. Operating below the water level allows it to push water upward without using a long suction pipe or requiring manual priming.

High-Head Water Delivery

A series of centrifugal impellers increases the water pressure progressively inside the pump. This multistage design makes it possible to lift water from deep boreholes and deliver it through long pipelines, over elevated terrain or into systems requiring additional outlet pressure.

Agricultural Water Supply

The pump can supply groundwater to farmland, greenhouses, orchards, livestock facilities, sprinkler networks and drip-irrigation systems. Flow should be matched to irrigation demand, while head should cover the dynamic water level, terrain elevation, pipe resistance and irrigation-equipment pressure.

Residential and Municipal Supply

For water-supply projects, the pump can fill elevated tanks, feed pressure vessels or deliver water directly into a distribution system. Level control is suitable for tank filling, while pressure sensors and variable-speed control can support automatic constant-pressure operation.

Industrial Water Transfer

The pump can be used for clean-water circulation, process-water supply, reservoir transfer and pipeline boosting in industrial facilities. Water quality and operating temperature must remain compatible with the selected pump materials and motor configuration.

Compact Borehole Installation

The vertical pump body is designed to fit within a well casing, reducing the need for surface equipment and pump-room space. The pump diameter must be selected according to the actual casing diameter, leaving sufficient clearance for installation and removal.

Matching the Pump to the Well

The selected flow should not exceed the amount of water the well can continuously provide. If pump capacity is too high, the water level may fall rapidly and expose the pump inlet. Static level, dynamic level and well yield should therefore be confirmed before model selection.

Calculating the Correct Head

The required head equals the vertical lift from the dynamic water level, plus the elevation to the final outlet, required discharge pressure and pipeline friction losses. Selecting only by well depth may result in insufficient water delivery or unnecessarily high energy consumption.

Water Conditions

This pump is designed for clean water rather than sewage. Sand, sediment and abrasive particles shorten hydraulic-component life, while salt or corrosive chemicals may require special materials. A water analysis is recommended when water quality is uncertain.

Safe Installation

The pump should be positioned below the lowest operating water level but above the sediment zone at the bottom of the well. The rising pipe must withstand the operating pressure, and the electrical cable should be secured without excessive tension or contact with sharp edges.

Automatic Pump Operation

The pumping system can be configured with tank-level control, well-level protection, automatic pressure control or remote monitoring. A properly matched control panel should also protect the motor against overload, phase loss, abnormal voltage and dry running.

Preparing an Accurate Quotation

Provide the required water volume, delivery pressure, well depth, casing diameter, static and dynamic water levels, discharge height, pipe length, water quality, power supply and cable length. If replacing an existing pump, send a clear nameplate photo and describe the current operating problem.

FAQ

How do I know which pump capacity is suitable?

The suitable capacity depends on daily or hourly water demand and the sustainable output of the well. Pump flow should meet system demand without removing water faster than the well can recover.

Is a deeper well always matched with a higher-head pump?

Not necessarily. The required head depends mainly on the dynamic water level, discharge elevation, outlet-pressure requirement and pipe losses, not simply the total drilled depth of the well.

Can this pump deliver water over a long distance?

Yes, provided the selected pump has enough head to overcome vertical elevation and friction losses in the delivery pipeline. Pipe diameter, length, valves and bends must be included in the calculation.

Can it work with a storage tank?

Yes. Water-level sensors can start the pump when the tank level falls and stop it when the tank is full. Low-level protection in the well should also be used to prevent dry running.

Can it maintain constant water pressure?

A compatible variable-frequency drive and pressure sensor can adjust pump speed according to demand. This arrangement is useful for irrigation networks and water-supply systems with changing consumption.

What happens if the well diameter is too small?

A pump that is too large cannot be installed safely and may restrict cooling-water movement around the motor. The internal casing diameter must be measured before the model is selected.

How far should the pump be kept above the well bottom?

The pump must remain above the area where mud and sand accumulate. The appropriate distance depends on the well structure, sediment level and position of the water-producing section.

Can the pump be installed horizontally?

The standard design is intended for vertical installation. Horizontal or inclined operation should only be considered when specifically approved for the selected pump and motor.

How can dry running be prevented?

Install a well-level sensor, electrode or other suitable dry-running protection device. The protection system should stop the motor before the water level falls below the permitted operating position.

What should be checked before starting the pump?

Confirm that the pump is submerged, the power supply matches the motor, electrical protection is active, rotation is correct and the discharge pipeline is open. Installation and commissioning should be completed by qualified personnel.
