22kW Motor Deep Well Submersible Pump with 72-108m Head and 3-Inch Outlet for Borehole Extraction

The SLAPK 200QJ50-90/6 is a 22kW deep well submersible pump with a catalog flow range of 46–54 m³/h, a head range of 72–108 m and a 3-inch outlet.

This model can be considered for borehole extraction, irrigation supply and elevated storage systems requiring greater head than a lower-head model at a similar flow.

A higher head requirement may result from a lower dynamic water level, a higher delivery point, greater pipeline losses or pressure required at the destination. The complete system requirement must be checked against the pump performance curve.

• Higher Head at the Same Catalog Flow Range: Compared with the 200QJ50-60/4, this model has the same listed flow range but a higher head range. It provides another selection option when the lower-head model cannot meet the system duty.
• 22kW Motor Configuration: The catalog specifies a 22kW motor. Verify the site electrical supply, starting requirements and protection settings before selecting the control panel and power cable. Motor power alone does not determine water output. Hydraulic performance depends on the pump configuration and operating point.
• 3-Inch Outlet Connection: The outlet size provides a reference for connection planning. Confirm the connection standard, pipe pressure rating, friction losses and valve arrangement for the complete installation.
• Selection Based on Operating Conditions: Use the dynamic water level when calculating the required head. Account for water-level changes during pumping, delivery elevation and any pressure required at the discharge point.

When the liquid and installation conditions are suitable, this model can be considered for:

• Borehole water extraction to elevated storage
• Agricultural irrigation supply
• Industrial utility water systems
• Rural and community water supply
• Well-to-tank transfer involving significant elevation or pipe resistance

For pressurized irrigation equipment, include the equipment's required operating pressure in the total head calculation.

Both models have a catalog outlet size of 3 inches. Choose the model whose verified curve matches the required duty point. A larger motor is not automatically the better choice.

Please provide:

• Required discharge flow
• Static and dynamic well water levels
• Delivery elevation relative to the pumping water level
• Pipe length, internal diameter and material
• Valves, elbows and other significant restrictions
• Required pressure at the destination
• Well internal diameter
• Water temperature and relevant water-quality information
• Site voltage, frequency and phase
• Planned operating hours and control method

For a requirement near 50 m³/h at 90 m total dynamic head, submit the duty point for checking against the model-specific curve before ordering.

Confirm the actual pump body, impeller and shaft materials for the water being pumped. The QJ designation alone does not establish seawater resistance, drinking-water approval or suitability for abrasive liquids.

Before installation, verify the complete assembly dimensions, minimum well diameter, submergence and cooling requirements. Power cable sizing must account for the motor configuration, cable length and installation conditions.

How does this model differ from the 200QJ50-60/4?

The 200QJ50-90/6 uses a 22kW motor and has a catalog head range of 72–108 m. The 200QJ50-60/4 uses a 15kW motor and has a head range of 48–72 m. Both list a flow range of 46–54 m³/h.

Does a 108 m head mean it can be installed in any 108 m well?

No. Pump head and installation depth are different specifications. Selection depends on the dynamic water level, delivery elevation, losses and discharge pressure. Permitted installation depth must be checked separately.

Can it deliver 54 m³/h at 108 m?

That cannot be concluded from the catalog ranges. Check the performance curve for the required flow and head combination.

Can it supply a pressurized irrigation system?

It can be evaluated for that application. Include the irrigation equipment's required pressure, elevation and pipeline losses in the duty calculation.

Does it come with a 380V, 50Hz motor?

The electrical configuration must be confirmed in the quotation and motor documentation. Do not assume voltage or frequency from the model designation alone.

Send your target flow and head, well information, pipework details, water quality and available electrical supply.

Specify the required quantity, cable length, control equipment and delivery destination to establish the correct configuration and scope of supply.
