The Wellhead-Motor Driven Vertical Long-Shaft Deep Well Fire Pump Set features modular concentric long-shaft transmission with 304 stainless steel impellers, 20Cr13 shafts, and hard alloy mechanical seals, delivering stable fire water at 5-110 L/s flow and ≤200 m head.
Resolves critical risks in conventional deep-well fire pumps: underwater motor maintenance hazards, shaft vibration/wear, efficiency degradation, and difficult in-well servicing.
Suitable for high-rise fire hydrant systems, industrial fire networks, municipal emergency supply, and combined domestic/fire water systems requiring GB 6245-2006/NFPA 20 compliance for non-corrosive clean water and neutral liquids.
Extended Service Life: 304 stainless steel impeller + 20Cr13 transmission shaft + tungsten carbide mechanical seals resist wear, corrosion & cavitation. Design lifespan ≥15 years—over 40% longer than standard deep-well fire pumps.
Significant Energy Savings: Concentric long-shaft direct drive + optimized hydraulic model achieve ≥78% efficiency at rated duty. Combined with wide high-efficiency range design, annual energy consumption drops by 20%–30% vs. traditional solutions.
Lower Maintenance Costs: Vertical long-shaft design + surface motor layout enables routine maintenance without well entry. Single technician completes seal/bearing replacement within 1.5 hours, reducing labor costs by 50%.
Lightweight & Compact Design: Modular column pipes + lightweight transmission shaft assembly reduce overall weight by ~15% 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 3 hours from positioning, compressing deployment cycle by 40%.
Building Fire Protection: Hydrant systems, automatic sprinkler systems, and water mist fire systems for high-rise/super high-rise buildings, commercial complexes, hotels, offices, and residential communities, ensuring stable water supply during power outages.
Industrial Fire Protection: Fire network water supply & process cooling backup for petrochemical, power plants, metallurgy/mining, pharmaceutical, and logistics warehouse facilities, supporting high-flow, high-head continuous operation.
Municipal Facilities: Emergency fire water supply guarantee for critical public infrastructure: hospitals, schools, subway tunnels, airports/ports, and data centers, meeting rapid response demands under complex conditions.
Domestic/Industrial Water Supply: Shared domestic/industrial water systems, building/municipal drainage, fixed fire system integration for industrial/mining enterprises, adapting to non-corrosive clean water & neutral liquid transport.
Media Compatibility: Non-corrosive clean water or neutral liquids with similar physicochemical properties. Solid particles ≤0.01% (by weight), pH 6.5–8.5, H₂S ≤1.5 mg/L, water temperature ≤40℃/104℉.

Note: For special conditions (high temperature / strong corrosion / high sand content / ultra-deep wells), 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 China Fire Equipment Quality Supervision & Testing Center. CCCF-certified models available upon request.
International Standard Compliance: Product design complies with NFPA 20 “Standard for the Installation of Stationary Pumps for Fire Protection”. Key performance indicators (flow-head curve, NPSH, vibration/noise) 100% compliant. Bilingual third-party test reports available.
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) + G2.5 dynamic balance calibration, guaranteeing zero-vibration, zero-leakage delivery.
Fast Standard Delivery: Covers flow 5–110 L/s, head ≤200 m, power 3–200 kW mainstream specifications. Standard 304 stainless steel impeller + 20Cr13 transmission shaft + tungsten carbide seals. Technical confirmation within 72 hours.
Deep Customization Capabilities:
Material Upgrade: Wetted parts optional in 316/duplex 2205 stainless steel for high-chloride, mild acid/alkali, or seawater desalination pretreatment conditions.
Transmission System: Optional bronze-base/tungsten carbide bearings, sand-resistant shaft sleeve assembly for sandy water or ultra-deep well (>200 m) conditions.
Structural Adaptation: Custom column pipe length, pump base flange standard switching (GB/ANSI/DIN), wellhead reinforcement brackets, outdoor rain-proof/anti-corrosion coating customization.
Intelligent Expansion: Pre-wired interfaces for pressure/flow/vibration sensors; supports integration with VFD cabinets, IoT remote monitoring, multi-pump rotation modules.
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.Motor junction box faces outward. Secure cable along well wall. Grounding resistance ≤4 Ω. Prime pump before initial startup. Jog test to verify rotation (clockwise from motor end).
Commissioning Process: Prime & vent → Jog test for direction → No-load run 10 min → Slowly open discharge valve to rated duty → Record current/pressure/vibration/bearing temp data → Acceptance.
Request the “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 long-shaft concentric transmission prevent bearing misalignment wear from radial runout?
Uses bronze-base self-lubricating bearings + support guide bearings every 6–8 m. Combined with G2.5 balanced impeller & pre-aligned coupling, tested radial runout ≤0.15 mm, bearing lifespan ≥20,000 hours.
Q2: How does surface motor design enable “maintenance without well entry”?
Motor + 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.
Q3: How to protect transmission system with trace solid particles (≤0.01%)?
Standard bronze-base bearings + sand-resistant shaft sleeves. Optional tungsten carbide shaft sleeves + enclosed oil-lubricated components. Tested: transmission efficiency decay ≤2%/year in 0.01% sand content, extending lifespan 3×.
Q4: 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.
Q5: How do dual certifications (GB 6245-2006 & NFPA 20) ensure fire acceptance?
Product design meets core requirements of both standards: flow-head curve, NPSH, vibration/noise 100% compliant. Supports bilingual third-party test reports, ensuring smooth fire acceptance for domestic & international projects.
