Installation Guidelines – Submersible Well Pumps
Proper installation is essential for correct pump performance and long service life.
Basic Requirements
- Always use a control box or pump controller
- Do not connect the pump directly to the power supply
- Install an output filter between controller and motor (recommended for long cable runs)
- Check power cable and joints before installation
- Use proper waterproof cable splicing kit
- Install the pump vertically inside the well
- Use a safety rope to secure the pump
- Never suspend the pump by the electric cable
- Use clean water only (no sand or debris)
Electrical Protection (Important)
For installations with long cable length:
- Install a motor protection filter (output filter / dv/dt filter)
- This protects the motor from voltage spikes and electrical stress
- Reduces risk of motor damage and insulation failure
Failure to install proper protection may lead to motor failure.
System Design Considerations
Pump performance depends on:
- Total dynamic head (depth + discharge height)
- Pipe size and length
- Voltage stability
- Correct controller and protection system
- Cable length and electrical protection
Incorrect installation may cause:
- Low water flow
- Motor overheating
- Electrical damage
- Pump failure
These issues are not product defects.
