Product Description

200QJH36-15-4kW Stainless Steel Deep Well Pump

The 200QJH36-15-4kW stainless steel deep well pump is a submersible well pump designed for groundwater extraction and general water supply applications. It delivers a rated flow of 36 m³/h and a rated head of 15 m, powered by a 4 kW submersible motor operating on 380V, 50Hz, three-phase power supply.

Constructed from stainless steel for mechanical strength and corrosion resistance, this pump is ideal for clean water and general groundwater applications including agricultural irrigation, industrial water supply, storage tank filling, landscape irrigation, and water treatment systems.

Key Product Advantages

Practical Flow Capacity

With a rated flow of 36 m³/h, this pump supports irrigation, tank filling, industrial water transfer, and other medium-capacity water supply applications. Actual flow depends on dynamic water level, pipe diameter, pipeline length, valves, fittings, and required discharge pressure.

Designed for Low-Head Water Transfer

The rated head of 15 m makes this pump suitable for systems with limited vertical lift, short pipelines, or relatively low resistance. Required total head includes vertical distance from dynamic water level, pipeline friction loss, valve resistance, and discharge pressure requirements.

Stainless Steel Construction

Featuring stainless steel material configuration for excellent mechanical strength and corrosion resistance in clean water and suitable groundwater applications. Stainless steel grade should be selected according to water temperature, pH value, chloride concentration, and chemical composition.

4 kW Three-Phase Motor

Powered by a 4 kW submersible motor using 380V, 50Hz, three-phase electrical supply. The three-phase motor can be integrated with a control panel providing overload, overcurrent, phase-loss, and dry-running protection.

Space-Saving Submersible Installation

The pump and motor operate underwater as an integrated unit, reducing the need for above-ground pump rooms. When correctly installed and adequately submerged, the surrounding water helps cool the submersible motor during operation.

Complete System Configuration

The pump can be supplied with compatible accessories according to project requirements:

Submersible motor
Pump control panel
Power cable
Rising pipe
Non-return valve
Isolation valve
Wellhead assembly
Water-level controller
Dry-running protection
Phase-loss protection
Overload and overcurrent protection

Note: Product structures, outlet sizes, internal components and material configurations may differ between manufacturers. Final specifications must be confirmed through the product nameplate, performance curve, technical agreement and sales contract.

Model Designation

The model "200QJH36-15-4kW" can generally be interpreted as follows:

200: Product series or well-diameter designation; required minimum well diameter must be confirmed from dimensional drawing
QJH: Series designation for deep well submersible pump; precise definition may vary by manufacturer
36: Rated flow of 36 m³/h
15: Rated head of 15 m
4kW: Matching motor power of 4 kW

Typical Applications

Deep well and borehole water extraction
Agricultural and farmland irrigation
Garden and landscape irrigation
Storage tank and reservoir filling
Industrial process water supply
Cooling-water system replenishment
Water treatment system supply or transfer
Municipal and rural water projects
Temporary construction water supply
Livestock and agricultural facility water supply

Information Required for Pump Selection

To verify whether this model is suitable for your project, please provide:

Well diameter and total depth
Static water level
Dynamic water level during operation
Required hourly flow rate
Required discharge pressure
Vertical distance from dynamic water level to discharge point
Horizontal pipeline length
Pipe diameter
Number of valves, elbows and other fittings
Water temperature and pH value
Sand content and chloride concentration
Required daily operating time
Continuous or intermittent operating requirements
Required cable length
Control-panel and protection requirements

The pump should not be selected according to well depth alone. If the actual total system head exceeds 15 m, delivered flow may decrease significantly. The final operating point should be checked against the manufacturer's pump performance curve.

Installation Guidelines

Confirm well diameter, well depth, casing straightness and water quality before installation
Verify that motor voltage, frequency and number of phases match site power supply
Use correctly sized power cable and control system for the 4 kW three-phase motor
Seal underwater cable joints using approved waterproof and insulation methods
Never lift or suspend the pump using the electrical cable
Maintain appropriate distance between pump inlet and well bottom
Prevent pump from drawing mud, sand or sediment from well bottom
Keep pump and motor adequately submerged during operation
Never operate pump without water
Install suitable non-return valve and isolation valve in discharge pipeline
Check motor rotation direction, operating current, water flow and discharge pressure during commissioning
Do not operate pump for extended periods against fully closed discharge valve
Use dry-running, phase-loss, overload and overcurrent protection where required

Operation and Maintenance

Regularly record operating voltage, current, flow, pressure and water level. Stop the pump and inspect the system if you notice:

Significant reduction in water flow
Abnormal operating current
Unstable discharge pressure
Excessive vibration
Unusual noise
Frequent protection trips

Possible causes include falling dynamic water level, blocked pump inlet, worn hydraulic components, pipeline leakage, incorrect motor rotation, unstable voltage, three-phase voltage imbalance, or sand/sediment accumulation inside the well.

Frequently Asked Questions

What is the flow rate of the 200QJH36-15-4kW well pump?

The rated flow is 36 m³/h. Actual water output depends on total system head, dynamic water level, pipe diameter, pipeline length and required discharge pressure. The actual duty point should be verified using the pump performance curve.

What is the rated head of this pump?

The rated head is 15 m. Pump head does not represent total well depth. Required system head must include vertical lift, pipeline friction loss and pressure required at the final discharge point.

What electrical supply does this pump require?

The pump uses a 380V, 50Hz, three-phase electrical supply. Before installation, confirm that site power supply matches motor nameplate and install suitable electrical protection.

Can this pump operate with a variable-frequency drive?

A variable-frequency drive may be used for soft starting, pressure control or flow adjustment when approved by pump and motor manufacturer. Before using a VFD, confirm permitted minimum frequency, motor cooling requirements, cable length and protection settings.

Can the stainless steel pump handle seawater?

Not necessarily. "Stainless steel" does not mean the pump is suitable for every corrosive liquid. Different stainless steel grades provide different corrosion resistance levels. Seawater and high-chloride liquids require confirmation of pump casing, impeller, shaft, fasteners, cable and sealing materials.

Is this pump suitable for continuous operation?

The pump may be used for continuous water supply when correctly selected, adequately submerged, properly cooled and operated within permitted duty range. Final continuous-duty conditions should be confirmed through manufacturer's technical documentation.

How can I obtain an accurate quotation?

Please provide well diameter, well depth, dynamic water level, required flow, actual lifting height, pipeline details, water quality, cable length, control requirements, quantity and delivery destination. This information allows suppliers to confirm correct configuration, accessories, delivery time and price.
