250QJH252-170-185KW Stainless Steel Submersible Well Pump
The 250QJH252-170-185KW is a high-capacity, multistage stainless steel submersible well pump designed for deep-well water lifting and demanding water-transfer projects. This vertical multistage hydraulic section is directly coupled to a submersible motor, allowing complete submersion below water level.
Technical Specifications
Model
250QJH252-170-185KW
Pump Type
Vertical multistage submersible deep well pump
Rated Flow
Approximately 252 m³/h
Rated Head
Approximately 170 m
Motor Power
185 kW
Number of Stages
10
Maximum Pump Diameter
Approximately 240 mm
Installation
Vertical submerged installation
Material Options
304 stainless steel, 316 stainless steel or project-specific materials
Important: Flow, head and power are interpreted from the common model designation. Final data must be confirmed against the manufacturer's datasheet, certified performance curve, nameplate and contract.
Key Features
High Flow and High Head
Designed for large-volume water delivery with 252 m³/h capacity, suitable for medium and large water-supply systems.
Ten-Stage Hydraulic Design
10-stage configuration progressively increases pressure for stable water delivery in deep wells and long pipelines.
Stainless Steel Construction
Wetted components available in 304 or 316 stainless steel for enhanced corrosion resistance and durability.
Integrated Pump and Motor
Compact vertical unit reduces above-ground equipment requirements and eliminates need for conventional pump rooms.
Submerged Operation
Low-noise operation with surrounding water providing natural motor cooling during operation.
Project-Specific Configuration
Customizable options including voltage, cable length, control panel, VFD, and protection devices.
Typical Applications
Deep-well water extraction
Large-scale agricultural irrigation
Municipal and community water supply
Industrial process and cooling-water systems
Mine, quarry and construction-site drainage
Reservoir and elevated-tank filling
Groundwater lifting and water-treatment projects
Emergency and long-distance water transfer
Recommended Operating Conditions
The pumped liquid should be clean water or liquids with similar physical and chemical properties. The minimum internal well diameter must exceed the pump's maximum outside diameter (240 mm) with sufficient clearance for cable, guards, and tolerances. The unit must remain adequately submerged during operation with sufficient water velocity for motor cooling.
Information Required for Pump Selection
Required flow rate in m³/h
Required total dynamic head in metres
Well depth, static water level and pumping water level
Minimum internal diameter of well casing
Water temperature, chemistry, chloride concentration and sand content
Available voltage and frequency
Delivery pipe size and connection standard
Required cable length
Starting and control method
Daily operating hours and expected starting frequency
Country or region of installation
Why Choose This Pump?
This model combines high flow, high head and compact submerged configuration. The ten-stage hydraulic arrangement provides progressive pressure generation, while optional stainless steel components support long-term use in wet and mildly corrosive environments. The integrated design reduces above-ground equipment requirements and is ideal for projects where installation space, noise control and continuous water delivery are important.
