The SLAPK 200QJ50-120/8 is a 30kW deep well submersible pump for groundwater extraction and water supply projects. The catalog lists a flow range of 46–54 m³/h, a head range of 96–144 m and a 3-inch outlet.
For buyers comparing pumps in the 200QJ50 range, this model offers a higher catalog head range than the 200QJ50-90/6 while retaining the same listed flow range. It can be evaluated for well-to-tank transfer, agricultural irrigation and industrial water supply where the required operating point matches its performance curve.

The flow and head ranges describe the catalog performance envelope; they are not values that can be combined freely. The required flow must be checked at the corresponding head on the model-specific performance curve.
When to Consider This Model
Well Water Transfer to Elevated Storage
When a well supplies a tank or reservoir above ground level, the pump must overcome the height difference from the pumping water level to the delivery point, together with pipe losses. The 200QJ50-120/8 can be considered when that combined requirement exceeds the capability of a lower-head model at the required flow.
Irrigation Supply with a Pressure Requirement
An irrigation system may need pressure at the field as well as sufficient water volume. Selection should account for the operating pressure of the irrigation equipment, the elevation difference and losses through pipes, filters and valves. Providing these details makes it easier to assess whether this model suits the complete system.
Replacement of an Existing Well Pump
If an existing pump no longer provides sufficient water, include its model, operating flow, discharge pressure and current pumping water level when requesting a replacement. A change in well conditions or pipe resistance should be investigated before choosing a higher-head pump.
Comparing the 90 m and 120 m Models
The 200QJ50-90/6 has a 22kW motor and a catalog head range of 72–108 m. The 200QJ50-120/8 has a 30kW motor and a catalog head range of 96–144 m. Both list a flow range of 46–54 m³/h and a 3-inch outlet.
The overlap in their head ranges does not mean they provide identical performance. Compare both curves at your required flow and consider the operating conditions before deciding which model to order.
Configuration and Scope of Supply
A useful quotation should identify the pump and motor configuration as well as the accessories included. Specify the required pump materials, electrical supply, cable length, outlet connection and control equipment. This helps you compare supplier quotations on the same basis.
For well installation, provide the borehole’s internal diameter and the planned installation arrangement. Pump dimensions, submergence and motor cooling requirements should be checked before the assembly is supplied.
Frequently Asked Questions
Can this pump deliver 50 m³/h at 120 m head?
That is a suitable duty point to submit for selection checking. Final confirmation should come from the performance curve and technical documentation for the quoted configuration.
Is it suitable for a 120 m deep well?
Well depth alone does not determine suitability. The pumping water level, delivery elevation, pipe losses and required outlet pressure determine the hydraulic duty. Installation depth limits must also be checked separately.
Can I use a 3-inch pipe for the entire discharge line?
The catalog lists a 3-inch pump outlet, but the pipeline diameter should be selected according to flow, pipe length and acceptable friction loss. A long discharge line may require a different diameter.
What should I include in a quotation request?
Send your target flow and head, well diameter, pumping water level, water conditions and available power supply. Also specify the quantity, cable length, required accessories and delivery destination.
