25kW Deep Well Submersible Pump with 58–68 m³/h Flow and 72–96 m Head for Submersible Borehole Pump Systems

The SLAPK 25kW deep well submersible pump delivers a catalog flow range of 58–68 m³/h and a head range of 72–96 m. The corresponding model is 200QJ63-84/6, with a catalog outlet size of 4 inches.

We recommend evaluating this model for groundwater extraction, irrigation supply and well-to-tank transfer where the required operating point matches its performance curve. Within the 200QJ63 range, it provides a higher-head option than the 22kW 200QJ63-70/5 while retaining the same listed flow range.

When a well supplies an elevated tank or reservoir, the pump must overcome the height difference from the pumping water level to the delivery point, together with pipeline losses. This model can be considered when the system needs more head than a lower-head pump can provide at the required flow.

For selection, send us the expected dynamic water level and delivery elevation. If the water level changes significantly during pumping, include that range so the assessment reflects the conditions the pump will actually encounter.

An irrigation system may need both substantial flow and pressure at the field. We therefore consider the irrigation equipment’s pressure requirement alongside elevation, pipe friction and losses through filters and valves.

If your pump feeds a storage reservoir instead of supplying irrigation equipment directly, tell us how the system is arranged. The two installations can have different head requirements even when their daily water demand is similar.

The 200QJ63-70/5 has a 22kW motor and a catalog head range of 60–82 m. The 200QJ63-84/6 has a 25kW motor and a catalog head range of 72–96 m. Both list a flow range of 58–68 m³/h and a 4-inch outlet.

We compare these models at your required duty point rather than selecting by motor power alone. Where their catalog head ranges overlap, the individual curves are needed to establish which model suits the project.

Our QJ series uses cast hydraulic components. The manufacturing process and the material grade are separate specifications, so the quotation should identify the actual pump body and impeller materials rather than relying on the series name alone.

Please specify the water conditions, electrical supply, cable length and control requirements. For a replacement project, include the existing pump nameplate and installation details so we can review the proposed pump, motor and connections against the current system.
