250QJ58-400-100KW Cast Iron Deep Well Submersible Pump

The 250QJ58-400-100KW Cast Iron Deep Well Submersible Pump is designed for deep well water extraction, agricultural irrigation, industrial water supply, and large-scale water transfer projects.

With a rated flow capacity of 58m³/h, a head of 400m, and a 100KW submersible motor, this pump is suitable for applications requiring deep well installation, high lifting height, and long-distance water delivery.

The QJ series adopts a multi-stage centrifugal structure, using multiple impeller stages to generate high pressure for deep underground water pumping and large-scale water supply systems.

The 250QJ58-400-100KW features cast iron construction, providing strong mechanical strength and structural durability for standard water pumping applications.

Cast iron advantages:

• High structural strength
• Suitable for deep well installation
• Good pressure resistance
• Suitable for fixed long-term operation

Suitable media:

• Groundwater
• Clean water
• Irrigation water
• Industrial water supply

For non-corrosive water sources, cast iron provides a practical pumping solution.

The main feature of this model is:

400m head capability

Suitable for:

• Deep groundwater extraction
• Elevated water tank supply
• Long-distance water transfer
• Complex terrain water supply

Actual pump selection should consider:

• Well depth
• Dynamic water level
• Pipeline length
• Pressure losses

The QJ series deep well pump uses a multi-stage impeller design.

Working principle:

The motor drives multiple impellers to increase water pressure step by step, allowing the pump to deliver water to higher elevations.

• Cooling circulation systems
• Industrial parks

Suitable for:

• Elevated tanks
• Mountain water supply
• Long-distance pipelines

Consider:

• Well depth
• Water level variation
• Transfer distance
• Required outlet pressure

The 400m head design is suitable for high-head water supply applications.

Flow determines water delivery capacity.

This model provides:

58m³/h flow rate

Suitable for:

• Industrial water supply
• Agricultural irrigation
• Deep well systems

Cast iron construction is suitable for:

• Clean water
• Standard groundwater

For saline or corrosive water conditions, alternative corrosion-resistant materials should be considered based on actual requirements.

The 250QJ58-400-100KW Cast Iron Deep Well Submersible Pump combines:

• 58m³/h flow capacity
• 400m high head performance
• 100KW motor configuration
• Cast iron construction
• Multi-stage centrifugal design

It is suitable for deep well water extraction, industrial water supply, agricultural irrigation, and large water transfer projects.

By matching water conditions, flow requirements, and head parameters correctly, this pump provides a practical solution for high-head and long-distance water supply applications.
