136 m³/h Flow Deep Well Submersible Pump

Product Description
300QJH136-220-140kW Stainless Steel Submersible Pump – 136 m³/h, 220 m Head
The 300QJH136-220-140kW stainless steel submersible pump is a high-head, multi-stage pump designed for demanding applications. Driven by a 140 kW water-filled submersible motor, it operates while fully submerged in water, making it ideal for deep-well water extraction, industrial water supply, mine dewatering, municipal engineering, and other high-head pumping requirements.
Technical Specifications
  • Model: 300QJH136-220-140kW
  • Pump Type: Multistage stainless steel submersible pump
  • Rated Flow: 136 m³/h
  • Rated Head: 220 m
  • Motor Power: 140 kW
  • Motor Type: Water-filled submersible motor
  • Installation: Vertical submerged installation
  • Power Supply: Three-phase
  • Voltage & Frequency: Configured according to project requirements
  • Pump Material: Stainless steel
  • Pumped Medium: Confirmed according to water analysis
The final operating point should be checked against the pump performance curve and actual system resistance before production.
Multistage Design for High-Pressure Applications
This pump utilizes multiple impeller stages to generate the pressure required for a rated head of 220 meters. This configuration is ideal for projects involving deep installation, significant elevation differences, or long discharge pipelines.
Total Dynamic Head Calculation Includes:
  • Vertical difference between water levels
  • Dynamic water level during pumping
  • Pipeline friction loss
  • Losses through valves, elbows, and fittings
  • Required pressure at the final discharge point
A pump selected only according to well depth may provide insufficient flow or operate outside its recommended performance range.
Stainless Steel Material Options
Different stainless steel grades can be selected according to the pumped liquid characteristics:
  • SS304: General clean-water applications with limited corrosive content
  • SS316: Improved corrosion resistance for industrial water conditions
  • SS316L: Lower-carbon stainless steel for demanding corrosive environments
  • Duplex 2205: Higher strength and chloride resistance
  • Super Duplex 2507: Severe marine and high-chloride applications
Material selection should be based on chloride concentration, pH value, liquid temperature, dissolved solids, and required operating time. A stainless steel pump should not automatically be described as suitable for seawater unless the actual water analysis and material grade support that application.
Water-Filled Submersible Motor
The 300QJH136-220-140kW pump is equipped with a water-filled submersible motor. Before installation, the motor must be filled with clean water according to the operating instructions.
During operation, the motor must remain adequately submerged. The surrounding water provides essential cooling. Dry running, insufficient submergence, or restricted water circulation may cause overheating and motor damage.
For horizontal installation or operation in a wide reservoir, a cooling jacket may be required. The installation arrangement should be reviewed before the pump is manufactured.
Suitable Applications
  • Deep-well groundwater extraction
  • Industrial water supply
  • Municipal water-transfer projects
  • Mine water supply and drainage
  • Reservoir water transfer
  • Raw-water intake systems
  • Water-treatment facilities
  • High-elevation water transfer
  • Agricultural irrigation
  • Cooling-water circulation
  • Seawater intake with suitable material grade
Final suitability depends on the actual liquid, installation structure, and hydraulic system requirements.
Electrical and Control Configuration
The motor voltage and frequency should match the project's electrical supply. Before quotation, confirm:
  • Rated voltage
  • Frequency
  • Three-phase power supply
  • Starting method
  • Cable length
  • Installation distance
  • Required electrical protection
For a 140 kW motor, the control system should be selected according to the local grid capacity and operating requirements. Available configurations may include a soft starter or variable-frequency control panel.
The control system should provide overload, phase-loss, short-circuit, and dry-running protection where required by the project design.
Installation Requirements
The pump is normally installed vertically and must operate fully submerged. Before installation, verify:
  • Well or installation diameter
  • Static water level
  • Dynamic water level
  • Minimum submergence
  • Pump-set length
  • Discharge-pipe size
  • Lifting and support arrangement
  • Power-cable routing
  • Non-return valve position
The pump should not operate with a blocked inlet, incorrect phase sequence, insufficient submergence, or closed discharge valve.
Information Required for Pump Selection
To confirm whether this model is suitable for your application, please provide:
  • Required flow in m³/h
  • Required total dynamic head
  • Liquid type and water analysis
  • Static and dynamic water levels
  • Installation depth
  • Pipeline diameter and length
  • Voltage, frequency and phase
  • Required stainless steel grade
  • Cable length
  • Daily operating hours
  • Control-panel requirements
Frequently Asked Questions
What are the rated parameters of the 300QJH136-220-140kW pump?
The rated operating point is 136 m³/h flow and 220 m head. The pump is driven by a 140 kW submersible motor.
Is the 220-meter head equal to the installation depth?
No. The rated head represents the pressure produced by the pump. Installation depth is only one factor in calculating total dynamic head.
What stainless steel material is available?
The pump can be configured in SS304, SS316, SS316L, duplex 2205 or super duplex 2507, depending on the liquid and corrosion conditions.
Can the pump be used for seawater?
It may be used for seawater only when the material is selected according to the water analysis. SS316L, duplex 2205 or super duplex 2507 may be evaluated based on chloride concentration and temperature.
Can the voltage and frequency be customized?
Yes. The voltage and frequency can be configured according to the customer's site power supply. These electrical parameters must be confirmed before production.
