Product Overview
QD / QXT Stainless Steel Submersible Clean Water Pump is a submersible centrifugal pump constructed with stainless steel wetted components for clean water transfer and drainage.
It addresses corrosion risk, installation space limitation, and surface-mounted pump priming instability in water supply and drainage systems.
It is applied in wells, water tanks, agricultural irrigation, household water supply, and light industrial clean water transfer scenarios.

How to Select a Pump Model
- Determine required flow rate and total head based on well depth and pipeline resistance.
- Confirm submersion depth and ensure motor cooling condition is satisfied.
- Verify liquid temperature ≤ 40°C.
- Select appropriate power rating according to duty point.
- Confirm discharge diameter compatibility with pipeline system.

Compliance & Quality Assurance
• Factory hydraulic performance test
• Insulation resistance and motor winding test
• Mechanical seal leakage inspection
• Pressure test of pump casing
• Material verification for stainless steel components
Safety Notice
• Do not operate without full submersion
• Do not run dry
• Disconnect power before maintenance
• Do not use in explosive environments
