The Diesel-Engine Driven Vertical Long-Shaft Deep Well Fire Pump Set is an emergency fire water supply equipment featuring an integrated diesel power unit with concentric long-shaft transmission, configured with an H-type right-angle gearbox (transmission efficiency ≥95%), modular stage arrangement, and 5-second rapid auto-start control system for stable high-flow high-head delivery.
Resolves four critical operational risks in conventional deep-well fire pumps: high maintenance hazards in underwater well environments, shaft vibration and uneven wear reducing service life, delayed start-up during grid power failure, and transmission efficiency degradation under prolonged operation.
Suitable for fire hydrant systems in industrial facilities, automatic sprinkler systems in high-rise buildings, municipal pipeline boosting, and emergency fire protection in docks/offshore platforms/remote plants without grid power, requiring compliance with GB 6245-2006 standard, zero grid dependency, and continuous operation under complex fire protection conditions.
Extended Service Life: Bronze-base self-lubricating bearings + 2Cr13 stainless steel transmission shaft resist wear & misalignment. Combined with G2.5 dynamically balanced impeller, design lifespan ≥20 years—over 40% longer than standard deep-well fire pumps.
Significant Energy Savings: Diesel direct drive eliminates power conversion losses. H-type gearbox transmission efficiency ≥95%. Rated fuel consumption ≤210 g/kW·h, reducing comprehensive energy consumption by 15%–20% vs. “grid + electric pump” emergency solutions.
Lower Maintenance Costs: Surface-concentrated layout + modular quick-connect interfaces enable routine maintenance without well entry. Single technician completes seal/bearing replacement within 2 hours, reducing labor costs by 55%.
Lightweight & Compact Design: Integrated motor + gearbox + pump base at wellhead reduces overall weight by ~18% for equivalent head ratings, lowering wellhead load requirements & lifting complexity.
Faster Installation: Pre-aligned flanges + quick-install pump base enable vertical alignment & fixation on-site. Standard units reach commissioning readiness within 4 hours from positioning, compressing deployment cycle by 40%.
Fire Extinguishing Systems: Indoor/outdoor hydrant systems, automatic sprinkler systems, and water mist fire systems for industrial enterprises, construction projects, and high-rise buildings, ensuring rapid water supply within 5 seconds during power outages.
Municipal & Industrial Water Supply: Shared domestic/industrial water systems, municipal network boosting, long-distance water conveyance, and industrial park water supply integration, supporting high-flow, high-head continuous operation.
Off-Grid/Power-Outage Emergency: Docks, offshore platforms, remote plants, tunnels, substations with unstable or absent grid power. Diesel independent drive ensures zero-delay pump startup during power loss.
Media Compatibility: Ambient clean water or neutral liquids with similar physicochemical properties. Solids ≤0.01%, pH 6.5–8.5, H₂S ≤1.5 mg/L, water temperature ≤40℃/104℉, free of solid particles & abrasive impurities.

Note: For special conditions (high temperature / strong corrosion / high sand content / ultra-deep wells / extreme cold), please consult our engineering team before selection. Customized pump solutions available.
Mandatory Fire Certification: Strictly manufactured per GB 6245-2006 “Performance Requirements and Test Methods for Fire Pumps”. Passed type testing by National Fire Equipment Quality Supervision & Inspection Center. CCCF-certified models available upon request.
Diesel Emission Certification: Equipped with premium domestic/imported diesel engines, compliant with GB 20891-2014 non-road mobile machinery emission standards (Stage IIIA/IIIB optional), meeting environmental access requirements.
International Quality System: ISO 9001:2015 certified. Core pressure-bearing components evaluated per CE/PED 2014/68/EU, meeting EU/US market entry requirements.
Factory Inspection Standard: Every unit undergoes 1.5× rated pressure hydrostatic test (5-min hold) + long-shaft concentricity calibration (radial runout ≤0.15 mm) + 5-second startup response verification + 24-hour load running test, guaranteeing zero-fault delivery.
Fast Standard Delivery: Covers flow 50–2000 m³/h, head 30–300 m. Standard domestic premium diesel + 2Cr13 stainless steel transmission shaft + bronze-base bearings. Technical confirmation within 72 hours.
Deep Customization Capabilities:
Material Upgrade: Wetted parts optional in 304/316/duplex 2205 stainless steel for high-chloride, mild acid/alkali, or seawater desalination pretreatment conditions.
Transmission System: Optional H-type/spiral bevel gearbox, universal joint coupling, sand-resistant bearing assembly for sandy water or ultra-deep well (>200 m) conditions.
Control Expansion: Standard auto-start control cabinet; optional dual-power transfer, remote monitoring, IoT cloud platform, auto-inspection/preheating/dual-battery modules.
Structural Adaptation: Custom column pipe length, pump base flange standard switching (GB/ANSI/DIN), wellhead reinforcement brackets, outdoor rain/soundproof canopy customization.
Please contact us for customization inquiries. Our engineering team delivers process proposals within 48 hours.
Installation Key Points:
1.Fix pump base horizontally on wellhead concrete foundation. Tighten anchor bolts symmetrically. Ensure pump shaft verticality ≤0.5 mm/m to prevent seal failure from long-shaft misalignment wear.
2.Connect column pipes via flanges. Install one pipe clamp per 10 m to ensure uniform axial load distribution. Never transmit pipe stress to pump body.
3.Use pre-aligned couplings for transmission shaft connection. Tighten bolts symmetrically per torque requirements. Manually rotate shaft 3 turns after initial installation to confirm no binding.
4.Route diesel exhaust system independently outdoors. Install silencer + rain cap. Ensure exhaust pipe slope ≥1% for condensate drainage. Position fuel tank below unit. Configure fuel line with filter + manual shut-off valve.
Commissioning Process: Vent fuel system → Manual shaft rotation check → Jog test for direction → 5-second startup response test → No-load run 10 min → Slowly open discharge valve to rated duty → Record RPM/pressure/vibration/exhaust data → Acceptance.
Request the “XBC Diesel Deep-Well Fire Pump Set Installation & Maintenance Manual” (PDF/English version) for complete dimensional drawings, column pipe connection specs, and commissioning logs.
Q1: How does diesel drive 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, complying with GB 6245-2006 emergency startup requirements.
Q2: How does H-type right-angle gearbox ensure ≥95% transmission efficiency with stable operation?
Uses spiral bevel gears + forced oil circulation lubrication. Gear meshing precision reaches ISO 1328-1 Grade 6. Combined with bronze-base self-lubricating bearings, tested full-load efficiency ≥95%, vibration ≤4.5 mm/s.
Q3: How does surface-concentrated layout enable “maintenance without well entry”?
Motor + gearbox + pump base integrated at wellhead. After loosening pump base bolts, rotor assembly can be lifted 300–500 mm as a unit, fully exposing mechanical seals/bearings for maintenance without personnel entering the deep well.
Q4: How to protect transmission system with trace solid particles (≤0.1%)?
Standard bronze-base bearings + sand-resistant shaft sleeves. Optional tungsten carbide shaft sleeves + enclosed oil-lubricated gearbox. Tested: transmission efficiency decay ≤2%/year in 0.1% sand content, extending lifespan 3×.
Q5: What structural reinforcements are needed for ultra-deep wells (>200 m)?
Recommendations: ① Upgrade transmission shaft to 304 stainless steel + add guide bearings every 4–6 m; ② Increase column pipe wall thickness by 10%–15%; ③ Reinforce wellhead foundation + add anti-sway brackets. Provide well depth for custom evaluation.
