200QJH150-150-110kW Stainless Steel Deep Well Pump

High-flow, high-head pumping for deep wells and engineered water systems

The 200QJH150-150-110kW stainless steel deep well pump is a multistage submersible pump developed for deep-well water lifting and engineered water-transfer duties. With a rated flow of 150 m³/h, a rated head of 150 m and a matched power rating of 110 kW, it is suited to systems that require continuous, high-capacity pumping at substantial pressure.

Its stainless steel construction supports demanding projects where corrosion resistance, mechanical strength and service life are important. Because the pump and submersible motor operate below the water level, the installation requires little surface space, produces low operating noise and may eliminate the need for a separate pump house. Material and electrical configurations can be selected to suit the water quality, well dimensions, installation depth and local power supply.

Main Technical Data

The stated duty point is intended for preliminary selection. Final efficiency, shaft power, operating range and actual duty must be verified against the approved performance curve and technical data sheet.

Key Benefits

High flow and high head

The combination of 150 m³/h rated flow and 150 m rated head supports deep-well abstraction, long-distance water transfer, reservoir filling and centralized water-supply duties.

Stainless steel wetted construction

Stainless steel wetted parts can improve resistance to corrosion in compatible liquids and reduce rust-related deterioration. The correct grade should be chosen after reviewing chloride content, pH, temperature and the complete water analysis.

Multistage submersible design

Multiple impeller stages build pressure progressively for high-head service. Submerged operation simplifies the surface layout and helps reduce operating noise.

Project-specific configuration

Material grade, voltage, frequency, cable, control panel, riser pipe and protection functions can be matched to the destination country, industry and site conditions.

System-focused protection

Correct pump selection together with dry-run, overload, phase-loss, voltage and temperature protection can improve operating stability and reduce shutdowns caused by abnormal conditions.

Typical Applications

• Deep-well groundwater abstraction and raw-water transfer

• Municipal, industrial-park and factory water supply

• Agricultural irrigation, sprinkler systems and water-conservancy projects

• Mine drainage, construction dewatering and emergency water supply

• Filling reservoirs, storage tanks and elevated tanks

• Long-distance water transfer and pressure-boosting systems

• Industrial liquids compatible with the selected stainless steel grade

How It Works

The submersible motor drives a stack of impellers. As liquid passes through each stage, its pressure rises before it is discharged through the riser pipe to the surface or downstream network. The complete pump set operates underwater, and the surrounding liquid assists with motor cooling. Minimum submergence, flow past the motor and permitted starting frequency must comply with the manufacturer’s instructions.

Information Required for Selection

1. Required flow and total dynamic head;

2. Borehole diameter, well depth, static water level and dynamic water level;

3. Liquid temperature, pH, chloride level, sand content and other water-quality data;

4. Supply voltage, frequency, phase and applicable local standards;

5. Installation depth, pipe length, pipe diameter and fittings;

6. Continuous or intermittent duty, daily operating hours and starting frequency;

7. Required materials, certifications, control panel, cable and accessories.

Installation and Operating Guidance

• Confirm the borehole diameter, maximum pump-set diameter, well straightness and dynamic water level before installation.

• Flush the well and remove sand and debris that could cause abrasive wear.

• Use correctly rated riser pipes, non-return devices, lifting components and waterproof cable joints. Never suspend the pump by its power cable.

• Keep the pump at the specified submergence and maintain adequate cooling flow around the motor.

• Provide suitable overload, short-circuit, phase-loss, under-voltage, over-voltage, dry-run and leakage protection.

• After initial start-up, check current, pressure, flow, vibration and sand content in the discharged water.

• Installation, wiring and commissioning must be completed by qualified personnel in accordance with the supplied manual.

Frequently Asked Questions

What does 200QJH150-150-110kW mean?

Under common deep-well pump naming conventions, the first “150" generally indicates a rated flow of 150 m³/h, the second “150" indicates a rated head of 150 m, and 110 kW is the matched power. The exact meaning of “200" must be confirmed against the manufacturer’s model code and should not be used alone to determine pump diameter or minimum well size.

Is the pump available in 304 or 316 stainless steel?

The stainless steel grade can be selected according to the project, subject to manufacturer confirmation. Grade 304 may be evaluated for general water, while water with higher chloride levels or stronger corrosivity may require an assessment for 316 or 316L. Final selection should be based on a complete water analysis.

Can this pump handle seawater?

“Stainless steel" alone does not make a pump suitable for seawater. Seawater service requires a specific review of materials, crevice and galvanic corrosion, seals, cable and motor construction, followed by written supplier approval.

Will the pump always deliver 150 m³/h at 150 m head?

No. The actual operating point is determined by the intersection of the pump curve and the system curve. Static head, pipe friction and local losses must be calculated, and the selected duty should fall within the permitted operating range.

What information is needed for a quotation?

At minimum, provide the required flow, total head, borehole diameter, well depth, static and dynamic water levels, water quality, electrical supply and installation depth. Complete information enables more accurate selection, pricing and lead-time confirmation.
