Performance Features: Discover the unmatched capabilities that define the Heavy Duty Flood Pump's superior performance.
1. Three Exceptional Starting Functions: The Heavy Duty Flood Pump is equipped with three state-of-the-art starting features for utmost reliability:
(1). Manual Start Function: Engage the manual start through a seamless manual-automatic interlock via the switch, ensuring a straightforward initiation of the pump.
(2). Automatic-Manual Functions: This feature allows for up to three starting attempts. Should these attempts fail, a 'starter failure alarm' is triggered, and the system exits the starting state. Upon a successful initial start, the time to reach rated load ranges between 5-10-15 seconds, contingent on the unit's capacity.
(3). Emergency Manual Direct Start Function: In case of self-controlled device failures, initiate an emergency manual start, empowering immediate response without delay.
2. Automatic Operation: In the event of a valid fire signal, the diesel fire pump activates automatically, ensuring uninterrupted performance even if the conventional power supply system falters. Upon restoration of normal power conditions, it seamlessly reverts to the electric pump.
3. Automatic Shutdown: Once the fire signal ceases, the diesel fire-fighting pump efficiently enters an automatic shutdown phase, optimizing energy usage and safety.
4. Battery Self-Charge Function: The diesel engine's electrical mains power autonomously charges the battery, guaranteeing a smooth and reliable start every time.
5. Comprehensive Indicating System: Equipped with indicators for readiness, manual and automatic start, operational status, shutdown, battery charge, and critical parameters such as oil pressure, coolant temperature, and battery voltage, this system ensures comprehensive real-time monitoring.
6. Advanced Alarm and Protection System: Receive critical alerts and protections against starting failures, overspeed, low oil pressures, high coolant temperatures, and battery voltage anomalies, safeguarding against unexpected faults.
7. State-of-the-Art Display Systems: Monitor vital engine metrics including oil pressure, speed, and battery charge, providing clear visibility into the pump's operating conditions.
8. Direct-Coupled Design: The diesel engine and water pump are seamlessly connected via a high-flexible coupling on a shared channel base, promoting a compact, efficient structure with reduced failure rates and vibrations, simplifying on-site installation.
9. High Pressure and Big Flow Capacity: Our selection of IS series single-stage and SOW series double-suction pumps cater to a variety of fire scenarios, delivering exceptional pressure and flow to meet diverse needs.
10. Adjustable Flow and Pressure: Featuring mechanical or electronic speed governors, our diesel pumps allow precise adjustments to maintain consistent flow and pressure, adapting to your specific requirements.
11. Pre-Heating Device for Water Temperature: Equipped with an AC220V cooling water pre-heating system, this feature ensures optimal operation even in environments where temperatures plummet below 5 ºC.
12. Dual Battery Circuit: In the event of a battery failure, a backup automatically engages, maintaining uninterrupted pump operation.
13. Maintenance-Free Battery: Designed for convenience, our battery requires no frequent supplemental fluid, reducing the need for constant attention and upkeep.
14. Automatic Timing Inspection Test: In the realm of fire systems, where safety stands paramount, our units remain vigilantly in standby mode. Seamlessly, they execute device testing for standby conditions, ensuring timely alerts are dispatched when needed.
Note: The above features are customizable to align with user preferences. Our expertise allows us to craft bespoke designs, expertly tailored to meet your unique specifications.
