Engineered to GB 6245 national standard with vertical multi-stage hydraulic design, delivering high-head, high-flow, zero-latency emergency water supply and pressure stabilization for fire protection systems.
Precisely deployed for high-rise buildings, commercial complexes, industrial facilities, and municipal fire networks, supporting integrated operation of hydrant, sprinkler, and pressure-stabilization systems.
Unlike standard multi-stage pumps, this series has passed CCCF type testing by the Ministry of Emergency Management. With stainless steel wetted parts, smart inspection interfaces, and wide temperature adaptability (-15℃ to +80℃), it achieves response within ≤30 seconds to rated duty, pressure rating up to 2.5 MPa, and ground-level maintenance accessibility, setting a new industry benchmark for fire pumps.
Extended Service Life: Wetted parts in standard 304/316 stainless steel + SiC mechanical seals resist corrosion, wear & cavitation. Design lifespan ≥15 years—over 40% longer than standard cast-iron fire pumps.
Significant Energy Savings: Optimized multi-stage impellers + low-loss diffuser design achieve ≥78% efficiency at rated duty. Combined with VFD pressure stabilization, comprehensive system energy consumption drops by 25%–35% vs. traditional solutions.
Lower Maintenance Costs: Surface-mounted motor + modular coupling design enables routine inspection/seal replacement without disconnecting piping. One technician completes maintenance within 45 minutes, reducing labor costs by 50%.
Lightweight & Compact Design: Vertical segmented structure eliminates heavy baseplate. Overall weight reduced by ~20% for equivalent head ratings, lowering floor load & lifting complexity.
Faster Installation: Pre-aligned flanges + quick-connect coupling interfaces enable vertical alignment & fixation on-site. Standard units reach commissioning readiness within 3 hours from unboxing, compressing installation cycle by 40%.
High-Rise Building Fire Protection: Hydrant system boosting for residential/office/hotel buildings, automatic sprinkler pressure stabilization, fire tank make-up water linkage.
Commercial Complexes: Zone pressure stabilization for fire networks in shopping malls/convention centers/transport hubs; high-pressure supply for large-space intelligent sprinkler systems.
Industrial & Warehousing: Fire boosting for factory workshops/logistics parks/hazardous material warehouses; foam extinguishing system supply; emergency fire tank circulation.
Municipal & Emergency: End-point boosting for municipal fire networks, temporary fire station supply, mobile emergency pump station integration.
Media Compatibility: Clean water or non-corrosive liquids with similar physicochemical properties. Insoluble solids content ≤0.1% (by mass). Temperature range: -15℃ to +80℃ (5℉ to 176℉).

Intelligent Expansion: Pre-wired interfaces for pressure/flow/level sensors; supports integration with auto fire control cabinets, IoT remote monitoring, auto-inspection rotation modules.
For customization inquiries, please contact us. Our engineering team will provide a tailored process solution within 48 hours.
Pre-Installation Checks: Verify foundation load capacity ≥1.5× pump set full-load weight, maintain ≥600 mm clearance. Confirm media temperature -15℃ to +80℃, solids ≤0.1%. Ambient temp ≤40℃, humidity ≤95% (non-condensing).
Installation Key Points:
1.Mount pump set vertically on solid foundation. Tighten anchor bolts symmetrically. Ensure pump shaft verticality deviation ≤0.5 mm/m to prevent seal failure from misalignment.
2.Connect inlet/outlet with flexible rubber joints. Never transmit pipe stress to pump body. Provide independent supports for inlet/outlet piping.
3.Motor junction box faces outward. Secure cable along pipe wall. Grounding resistance ≤4 Ω. Manually rotate shaft 3 turns before startup.
4.Prime pump & vent air. Jog test to verify rotation (clockwise from motor end). Confirm insulation resistance ≥50 MΩ before operation.
Commissioning Process: Prime & vent → Jog test for direction → No-load run 5 min → Slowly open discharge valve to rated duty → Record current/pressure/vibration/temp rise → Acceptance sign-off.

Q1: How does the fire pump reach rated duty within ≤30 seconds during emergencies?
Features “always-primed + pre-pressurized” design with pump chamber kept water-filled daily. Upon fire alarm, motor starts directly at line frequency. With low-inertia impeller, tested to reach rated flow within 30 seconds, complying with GB 6245 “≤5 min water supply” mandatory requirement.
Q2: What customizations are needed for media temperature >80℃?
Standard type suits -15℃ to +80℃. For >80℃: ① High-temp mechanical seals (FKM O-rings + SiC mating faces); ② Pump body insulation jacket; ③ Enhanced motor cooling. Specify temperature parameters during ordering.
Q3: How does vertical multi-stage design prevent bearing damage from axial overload?
Integrated heavy-duty thrust bearing assembly + hydraulic balance drum automatically balances >90% of axial thrust. Residual axial load is borne by angular contact ball bearings with design lifespan ≥20,000 hours, supporting continuous maintenance-free operation.
Q4: Can CCCF certification be directly used for overseas fire project acceptance?
CCCF is China’s mandatory fire certification. Overseas projects typically require target-market approvals. We provide bilingual test reports, NFPA 20/EN 12845 benchmarking, and assist with CE/UL/FM evaluation.
Q5: How to prevent flow competition & pressure fluctuation during multi-pump parallel operation?
Use identical pumps with independent VFDs. Install check valves & pressure sensors on discharge headers. Control system implements “master-slave rotation + PID closed-loop” algorithm for dynamic load balancing, maintaining pressure fluctuation within ±0.02 MPa.
