200QJ50-180/12 Deep Well Submersible Pump

The SLAPK 200QJ50-180/12 is a 45kW deep well submersible pump with a catalog flow range of 46–54 m³/h, a head range of 153–207 m and a 3-inch outlet. It can be considered for groundwater supply projects where the system requires greater head than the 200QJ50-150/10 can provide at the target flow.

Typical projects include well water transfer to elevated storage, agricultural water supply and industrial utility systems. The final selection should match the required flow and total dynamic head, with materials and installation conditions confirmed for the water being pumped.

• Model: 200QJ50-180/12

• Motor power: 45 kW

• Catalog flow range: 46–54 m³/h

• Catalog head range: 153–207 m

• Outlet size: 3 inches

• Pump series: QJ

• Pump and impeller materials: Specify in the quotation

• Voltage, frequency and phase: Confirm for the selected motor

The listed flow and head ranges cannot be combined freely. A requirement such as 50 m³/h at 180 m total dynamic head should be checked against the performance curve for the quoted configuration.

A well with a low pumping water level requires the pump to overcome a greater vertical lift before water reaches the surface. If the delivery point is elevated or requires pressure, those requirements must also be included. The 200QJ50-180/12 provides a higher-head selection option within the same catalog flow range as the lower-head 200QJ50 models.

For reliable selection, provide the expected pumping water level rather than the total well depth alone. Where water levels vary seasonally, include the anticipated operating range so the proposed pump can be assessed under different conditions.

For an open tank or reservoir, the head calculation should include the elevation difference from the pumping water level to the destination and the losses through the pipework. For pressurized irrigation, add the pressure required by the irrigation equipment, together with losses through filters, valves and fittings.

These details help establish whether this model suits the project. Selecting a pump only from the delivery height can leave part of the system requirement unaccounted for.

The 200QJ50-150/10 has a 37kW motor and a catalog head range of 128–173 m. The 200QJ50-180/12 has a 45kW motor and a head range of 153–207 m. Both list a flow range of 46–54 m³/h and a 3-inch outlet.

If the lower-head model cannot provide the required flow at the calculated system head, the 200QJ50-180/12 can be evaluated as the next higher-head option. Compare the model-specific curves before deciding; the overlapping catalog ranges do not establish identical performance.

To prepare a comparable quotation, specify the required pump materials, electrical supply, cable length, outlet connection and control equipment. Confirm which accessories are included in the price and which are quoted separately.

The well’s internal diameter, pump assembly dimensions, installation depth and motor cooling conditions also need to be checked. For a replacement project, provide the existing pump nameplate and operating information so the proposed configuration can be assessed against the current installation.

Well depth alone is insufficient for selection. The pumping water level, delivery elevation, pipe losses and required discharge pressure determine the hydraulic duty. Permitted installation depth must be checked separately.

This cannot be concluded from the catalog ranges. The flow available at a particular head must be read from the model-specific performance curve.

It identifies the catalog outlet size. The discharge pipeline should be sized according to the flow, length and acceptable friction loss, with the connection standard confirmed before ordering.

Provide the site voltage, frequency and phase, together with the planned cable length and starting method. The motor, cable and control equipment should be selected as a coordinated system.

Send SLAPK your required flow and head, well diameter, pumping water level, water conditions and available power supply. Include the quantity, cable length, accessories and delivery destination.

If the total head is not yet known, provide the site elevations and pipework details for selection review. Contact SLAPK for a 200QJ50-180/12 pump configuration and quotation.
