22kW Deep Well Submersible Pump with SS304 Impeller and 160 m³/h Flow Rate for Borehole Water Extraction

The 250QJ160-35/2-22kW deep well submersible pump is engineered for high-volume clean water extraction and transfer applications. With a rated flow of 160 m³/h, head of 35 meters, and powered by a 22 kW three-phase motor, this pump is ideal for boreholes, agricultural irrigation, industrial water supply, reservoir transfer, and municipal water projects.

Constructed with durable cast iron housing and SS304 stainless steel impeller for enhanced corrosion and wear resistance, the vertical multistage design operates completely submerged, saving installation space while delivering stable hydraulic performance.

• High-Flow Water Delivery: Rated flow of 160 m³/h supports continuous transfer of large water volumes
• Durable Construction: Cast iron hydraulic components with SS304 impeller for enhanced corrosion resistance
• Compact Vertical Design: Integrated motor and pump unit requires no separate pump room
• Stable Submerged Operation: No suction priming required with reduced risk of air intake
• Custom Electrical Configuration: Cable length, protection, and control panels tailored to site requirements

• Deep well and borehole water extraction
• Agricultural irrigation systems
• Industrial process water transfer
• Municipal and rural water supply
• Reservoir and water tank transfer
• Livestock and farm water supply
• Construction site water supply
• Factory cooling and circulation systems

Before installation, confirm well diameter, dynamic water level, installation depth, pipeline size, power supply, and required cable length. The pump must remain fully submerged during operation with sufficient inlet clearance from the well bottom to reduce sediment intake.

A suitable control panel should include overload, phase-loss, short-circuit, over-voltage, under-voltage, and dry-running protection. The pump must not operate without water to prevent motor and bearing damage.

Always lift the complete pump using appropriate lifting devices or supporting pipes—never suspend the pump by the electrical cable.

Pump selection should be based on actual duty point requirements rather than motor power alone. Provide the following information for accurate selection:

• Required flow rate and total head
• Well diameter and total depth
• Static and dynamic water levels
• Vertical and horizontal pipeline length
• Pipe diameter and fitting arrangement
• Voltage, frequency, and phase
• Water quality and temperature
• Installation method and required cable length

• Is this pump suitable for seawater?
  Standard cast iron version is for freshwater. For seawater or corrosive media, consider SS316L, duplex stainless steel 2205, or super duplex stainless steel 2507 based on water analysis.
• Can the cable length be customized?
  Yes, cable length and protection can be configured according to installation depth and site requirements.
• Can this pump operate horizontally?
  Normally installed vertically. Horizontal installation requires confirmation of motor cooling, bearing support, and installation structure.
• Does the pump need to remain underwater?
  Yes, pump and motor must remain adequately submerged for proper water intake and motor cooling.
• What information is needed for a quotation?
  Provide required flow, total head, voltage, frequency, well diameter, installation depth, water quality, cable length, and quantity.
