The Diesel Fire Pump Set features diesel direct drive, automatic control module, and triple-start protection, supporting horizontal single-stage/double-suction/multistage pump options for 5-second emergency start-up and rated flow/pressure delivery.
It solves grid dependency, delayed start-up during power failure, and off-grid inoperability in conventional electric fire pumps.
It is suitable for high-rise fire hydrant systems, industrial fire networks, municipal emergency supply, and remote off-grid sites requiring operation at >90KPa atmospheric pressure, 5℃-40℃ ambient temperature, and ≤80% relative humidity.
Extended Service Life: Heavy-duty diesel engine + high-strength common channel steel base + precision direct-coupled structure resist vibration & fatigue. Design lifespan ≥15 years—over 35% longer than standard mobile diesel pumps.
Significant Energy Savings: Diesel direct drive eliminates power conversion losses. Combined with mechanical/electronic governor for precise duty matching, rated fuel consumption ≤215 g/kW·h, reducing comprehensive energy consumption by 15%–20% vs. “generator + electric pump” solutions.
Lower Maintenance Costs: Modular quick-install design + top inspection ports + visual instrument layout enable routine maintenance without special tools. One technician completes filter/oil/belt replacement within 1 hour, reducing labor costs by 50%.
Lightweight & Compact Design: Diesel-pump direct coupling eliminates independent coupling & heavy foundation. Overall weight reduced by ~20% for equivalent power ratings, lowering transport costs & installation space requirements.
Faster Installation: Pre-installed coupling interfaces + pre-drilled common base enable positioning → pipe connection → commissioning within 3 hours, compressing deployment cycle by 40%.
Building Fire Protection: Hydrant systems, automatic sprinkler systems, water mist extinguishing systems for high-rise/super high-rise buildings, rapid pump startup within 5 seconds of power loss.
Industrial Fire Protection: Fire networks & process cooling backup for petrochemical, power plants, metallurgy/mining, pharmaceutical facilities.
Municipal Facilities: Waterworks intake boosting, subway tunnels, airports/ports, data centers emergency fire water supply.
Off-Grid/Power-Outage Scenarios: Remote areas, temporary construction sites, offshore platforms, field operations with unstable grid power.
System Integration: Can be integrated with electric fire pumps and booster pumps for automatic water supply systems, supporting remote linkage with fire control centers.

Installation Key Points:
1.Mount unit horizontally on solid concrete foundation. Tighten anchor bolts symmetrically. Ensure pump-diesel shaft alignment deviation ≤0.05 mm to prevent vibration transmission.
2.Connect inlet/outlet with flexible rubber joints. Never transmit pipe stress to pump body. Provide independent supports for inlet/outlet piping.
3.Route diesel exhaust system independently outdoors. Install silencer + rain cap. Ensure exhaust pipe slope ≥1% for condensate drainage.
4.Position fuel tank below or beside unit. Configure fuel line with filter + manual shut-off valve. Pre-supply fuel manually to vent air before initial startup. Check oil/coolant/battery levels.
Commissioning Process: Vent fuel system → Manual shaft rotation check → Jog test for direction → No-load run 10 min → Load linkage test (simulate power outage auto-start) → Record RPM/pressure/vibration/exhaust data → Acceptance.

Q1: How does triple-start guarantee achieve pump startup within ≤5 seconds of power loss?
Control cabinet monitors grid status in real-time. Upon power loss signal, diesel engine ignites within 2s + reaches rated RPM within 3s. With pre-lubrication system, tested to deliver rated flow within 5 seconds.
Q2: How does intelligent dual-source switching ensure seamless electric/diesel pump transition?
Uses “grid-priority + auto-failover” logic: Electric pump runs when grid is normal; upon power loss/phase-loss/electric pump fault, control cabinet triggers diesel start within 0.5s, auto-switches back after recovery. Pipeline pressure fluctuation during switching ≤±0.05 MPa.
Q3: How does real-time monitoring ensure operational safety and traceability?
Monitors 12+ key parameters (oil pressure, water temperature, RPM, battery voltage, etc.) in real-time. Fault signals processed by PLC trigger auto-shutdown + audio-visual alarm within 0.5 seconds, supporting historical data logging & remote query.
Q4: What power adjustments are needed for high-altitude (>1000m) installations?
Thin air causes diesel power derating ~10%/1000m. Recommend reserving 10%–15% power margin during selection, or adding
Q5: What preparations are needed for startup in extreme cold (<-15℃)?
Standard water-jacket preheating + low-temp starting battery guarantees successful startup within 3 attempts at -15℃. For <-20℃, add fuel heater + intake preheating module, and use -35# low-temperature diesel.
