45kW Deep Well Submersible Pump, 46–54 m³/h, 165–225 m Head

The SLAPK 45kW deep well submersible pump offers a catalog flow range of 46–54 m³/h and a head range of 165–225 m. It can be considered for groundwater extraction, elevated storage supply and irrigation projects requiring substantial lifting head.

The corresponding model is 200QJ50-195/13, with a catalog outlet size of 3 inches. Selection should be based on the required flow at the calculated total dynamic head, together with the well conditions, water quality and available electrical supply.

The listed flow and head ranges are not independently selectable values. They do not mean the pump delivers 54 m³/h at 225 m head. The required operating point must be checked against the model-specific performance curve.

When the pumping water level is low, the pump must overcome a greater vertical distance before water reaches the delivery point. Elevated tanks, pipeline resistance and pressure required at the destination add to that requirement. This model can be evaluated where those combined demands exceed the capability of a lower-head pump at the required flow.

For selection, provide the pumping water level rather than the total well depth alone. If water levels change during extended pumping or across seasons, include the expected range so the proposed pump can be assessed under the relevant operating conditions.

For well-to-reservoir transfer, the system calculation should include the elevation difference from the pumping water level to the reservoir and losses through pipes and fittings. For pressurized irrigation, include the pressure required by the irrigation equipment and losses through filters and valves.

The pump can also be considered for industrial utility water supply where the liquid and installation conditions are suitable. Confirm the material configuration against the actual water quality before ordering.

The 200QJ50-195/13 and 200QJ50-180/12 both have catalog motor ratings of 45kW and flow ranges of 46–54 m³/h. Their head ranges differ: 165–225 m for the 195/13 model and 153–207 m for the 180/12 model.

For buyers, this means a quotation described only as a “45kW deep well pump” is not enough to establish suitability. Specify the complete model and required duty point, then compare the proposed performance curves and supply configurations.

A project quotation should identify the pump materials, motor specification, outlet connection, cable length and control equipment. Confirm whether the quoted price includes the required accessories so different offers can be compared on the same basis.

For a replacement project, provide the existing pump nameplate, current water output and pumping water level. Explain any changes in pipeline length, delivery height or water demand. These details help determine whether the replacement should retain the original duty or meet a revised requirement.

Submit this duty point for checking against the performance curve of the quoted configuration. The model designation provides a selection reference but does not replace performance verification.

No. Hydraulic head represents the system’s lifting and pressure requirement. Permitted installation depth and submergence must be checked separately.

No. Actual flow depends on the pump performance curve and the connected system. Motor power alone does not establish the delivered flow.

Suitability depends on the complete material configuration and permitted operating conditions. Provide water-quality information, including salinity or sand content where relevant, before selecting the pump.

Send SLAPK your required flow and total head, well diameter, pumping water level, water conditions and electrical supply. Include the quantity, cable length, control requirements and delivery destination.

If the total head has not yet been calculated, provide the delivery elevation, pipeline length and diameter, and required destination pressure for selection review.
