200QJ50-150/10 Deep Well Submersible Pump, 37kW

The SLAPK 200QJ50-150/10 is a 37kW deep well submersible pump with a catalog flow range of 46–54 m³/h and a head range of 128–173 m. Its catalog outlet size is 3 inches.

This model can be evaluated for groundwater supply projects with greater lifting or pressure requirements, including transfer from a lower pumping water level, delivery to elevated storage and water supply through pipelines with substantial resistance. Selection depends on the required flow and total dynamic head.

• Model: 200QJ50-150/10

• Motor power: 37 kW

• Catalog flow range: 46–54 m³/h

• Catalog head range: 128–173 m

• Outlet size: 3 inches

• Installation type: Submersible well installation

• Pump materials: Confirm for the supplied configuration

• Electrical specification: Confirm voltage, frequency and phase before ordering

The maximum listed head is not a guaranteed head at the maximum listed flow. Check the complete duty point against the performance curve for the selected pump configuration.

Compared with the 30kW 200QJ50-120/8, this model has a higher catalog head range while retaining the same listed flow range. It provides another option when the required flow cannot be achieved at the system head using the lower-head model.

The pumping water level may change during operation or across seasons. For projects with significant drawdown, provide the expected operating water-level range so the pump can be assessed under more than one condition. Selecting from a single static water-level measurement may overlook the actual lifting requirement.

The 3-inch outlet is a starting point for connection planning. The discharge pipe, joints, valves and fittings should be selected for the system’s pressure conditions, including relevant shutoff and transient conditions. Confirm the connection standard and pressure requirements before purchasing accessories.

Where water quality and installation conditions are suitable, the 200QJ50-150/10 can be considered for:

• Groundwater extraction from wells with low dynamic water levels

• Well water transfer to elevated tanks or reservoirs

• Agricultural irrigation requiring lift and delivery pressure

• Industrial utility water supply

• Water transfer systems with substantial pipeline losses

For longer pipelines, calculate friction losses using the intended pipe diameter and flow. Distance alone does not establish the required pump head.

The 200QJ50-120/8 has a 30kW motor and a catalog head range of 96–144 m. The 200QJ50-150/10 has a 37kW motor and a catalog head range of 128–173 m. Both list 46–54 m³/h flow and a 3-inch outlet.

Choose according to the verified operating point. An unnecessarily high-head pump can create pressure or flow conditions that the system does not require, so motor power should not be the deciding factor.

Provide the required flow, pumping water-level range, discharge elevation and destination pressure. Include pipe length, internal diameter and major fittings so the complete head requirement can be assessed.

The quotation should also specify pump materials, motor electrical data, cable length, starting and control equipment, outlet connection and the accessories included. Water containing salt, sand or other potentially damaging constituents requires a material and operating-condition review.

No. The head value in the model designation should not be treated as an installation-depth limit. Hydraulic head and permitted submergence are separate specifications.

Not necessarily. These two models share the same catalog flow range but have different head ranges. Actual water output depends on the pump curve and connected system.

It may be considered if the system requires greater head, but it is not an automatic replacement. Review the duty point, electrical capacity, controls and discharge-system pressure requirements first.

Include the required control functions and cable length in your inquiry. The quotation should state the available configuration and clearly identify which accessories are included.

Send SLAPK your required flow and head, well information, water conditions and power supply details. Include the quantity, accessory requirements and delivery destination for a project-specific quotation.

For replacement projects, a photo of the existing pump nameplate and current operating information can help identify what needs to change.
