18.5 kW Deep Borehole Water Pump with 3-Inch Outlet

The vertical pump unit is lowered directly into a well with a minimum applicable diameter of 200 mm. Submerged operation eliminates a long suction line, reduces above-ground installation requirements and normally removes the need for pump priming.

The pump has a 3-inch discharge connection for the rising pipe. Correct pipe sizing is essential because excessive friction in an undersized or very long pipeline can reduce the available flow at the final outlet.

The pump can be connected to tank-level sensors for automatic filling or to a pressure-control system for direct pipeline supply. A compatible variable-frequency drive may be used when the system requires changing flow or constant pressure.

The 200QJ combines deep-well installation, 32 m³/h water capacity, 112 m head and a 25 HP motor in one submerged unit. It is suitable for projects requiring clean-water delivery without the suction-depth limitations and priming requirements of a surface pump.

The pumped liquid should be clean water without sewage, fibrous material or large particles. The amount of sand and the chemical composition of the water should be checked because abrasive or corrosive conditions may require a different pump configuration.

Before purchasing, provide the well depth, internal diameter, static water level, dynamic water level, discharge elevation, horizontal pipe length, required outlet pressure and power supply. This information is necessary to verify whether the 32 m³/h and 112 m duty matches the project.

Install the pump vertically below the lowest operating water level and above bottom sediment. Use a correctly rated rising pipe, cable and control panel, and include dry-running, overload, phase and voltage protection.

What is this pump mainly used for?

It is used to extract clean water from deep wells for tank filling, irrigation, rural water supply, farm water systems and industrial clean-water transfer.

Is 32 m³/h the guaranteed flow in every installation?

It is the rated flow at the specified operating point. Actual flow depends on the total system head, power conditions and well yield.

Is the motor rated in kilowatts or horsepower?

The motor rating is 18.5 kW, approximately equivalent to 25 HP. Kilowatt is the specified metric motor-power rating.

Is the outlet really 3 inches?

Yes. The specified discharge outlet size is 3 inches. Pipe connection standards and exact interface dimensions should be confirmed before ordering.

Can the pump fill a high-level water tank?

Yes, if the calculated total head remains within the pump’s suitable operating range. The tank elevation, dynamic water level and pipe friction must all be included.

Can it work continuously?

Continuous operation is possible when the pump is correctly selected, adequately submerged, properly protected and supplied by a well with sufficient water yield.

Can this pump be used for drinking-water supply?

It can form part of a clean-water supply system when its materials, installation and local water-quality requirements are suitable. The water itself should be tested and treated as required before consumption.

What details should be included in an inquiry?

Include the model, required quantity, well diameter, water level, well depth, delivery distance, power supply, cable length and application. For replacement orders, also provide the old pump nameplate.
