Precautions for Use
To ensure safe and efficient operation, follow these important usage guidelines:
- Material customization: Standard model includes stainless steel shaft and aluminum bronze impeller. Specify if different materials are required.
- Routine operation: Run the jockey pump at least once every six months to prevent startup difficulties.
- Leak prevention: The water inlet pipeline must be completely sealed to prevent air leakage.
- Avoid cavitation: Do not run the pump for long periods under cavitation conditions.
- Motor protection: Avoid running the motor under high flow and low lift conditions for extended durations.
- Monitor performance: Regularly check motor current values and ensure the pump operates within design limits.
- Supervised operation: Always monitor the pump during operation to prevent accidents.
- Regular maintenance: Inspect and replace worn parts such as bearings and seals yearly or as needed.
- Mechanical seal care:
- Use clean lubricating fluid without solid particles.
- Never operate under dry running conditions.
- Rotate the motor manually several times before startup to protect the seal.
