(2) Automatic Run: Diesel engine starts automatically if the electric fire pump fails or power is lost.
(3) Self-Charging: Batteries are charged via an industrial power diesel engine charging motor.
(4) Protection System: Warning for 3-fail starts, overspeed, low oil pressure, high water temperature, and low fuel level.
Troubleshooting Guide
| Fault |
Cause |
Solution |
| No water suction / Vibration |
Insufficient water pouring; Pipe leak; Suction too high |
Check bottom valve; Tighten parts; Reduce suction height |
| High vacuum / No suction |
Bottom valve jammed; High resistance; Filter jammed |
Check valve; Replace pipe; Clean filter |
| Low Flow Outcome |
Air sucked; Water level drops; Impeller jammed |
Clear leak; Increase submerged depth; Clean impeller |
