13kW Deep Well Submersible Pump with 29–35 m³/h Flow Range and 71–96 m Head Range for Borehole Water Supply

The SLAPK 13kW deep well submersible pump is a selection option for groundwater extraction, agricultural irrigation and well-to-tank transfer. The corresponding model, 175QJ32-84/7, has a catalog flow range of 29–35 m³/h, a head range of 71–96 m and a 3-inch outlet.

We select the pump according to the flow required at the system's total dynamic head. The well's water yield, pumping water level, water quality and available electrical supply help us establish whether this model suits the project and which configuration to quote.

The flow and head ranges cannot be combined freely. They do not mean the pump delivers 35 m³/h at 96 m head. We check the required operating point against the performance curve for the proposed configuration.

For agricultural projects, we start with the required water volume and available pumping hours to establish the target flow. We then consider whether the pump fills a reservoir or supplies irrigation equipment directly, since these arrangements can have different pressure requirements.

When supplying an open tank, the pump must overcome the elevation difference from the pumping water level to the delivery point and the losses through the pipework. For direct irrigation supply, the pressure required by the irrigation equipment must also be included.

This model can also be considered for rural water supply and industrial utility water transfer where the water and installation conditions are suitable. Drinking-water applications require separate confirmation of the relevant materials and approvals.

Our QJ series uses cast hydraulic components. We distinguish the manufacturing process from the material specification: casting alone does not identify whether a component is cast iron, stainless steel or another material.

For ordinary non-corrosive water, our catalog identifies HT200 cast iron as a material option. We confirm the actual pump body, impeller and other component materials in the quotation according to the proposed configuration and water conditions. If your project specifies particular material grades, include them in the inquiry.

Total well depth is not enough to determine the required pump head. We use the dynamic water level during pumping, the delivery elevation, pipeline losses and any pressure required at the destination.

If the water level changes significantly during operation or across seasons, provide the expected range. Available pumping-test results are also useful because the selected flow should be compatible with the well's sustainable yield.

A requirement near 32 m³/h at 84 m total head can be submitted for checking against this model's performance curve. The model designation alone does not replace that verification.

Before ordering, we confirm the pump assembly dimensions against the well's internal diameter and required installation clearance. The "175" in the model designation should not be treated as a verified measurement of the complete pump assembly.

The catalog specifies a 3-inch outlet, while the connection standard and discharge pipe diameter should be confirmed for the installation. We also review the site voltage, frequency, phase, cable length and starting requirements. If a different frequency is requested, the hydraulic performance must be checked for that frequency.
