The Direct-Coupled Horizontal Fire Pump is a single-stage centrifugal fire pump with compact direct-coupled structure, hard alloy double-end mechanical seals, and back pull-out design, featuring optimized hydraulic model and ISO 1940 G6.3 balance for stable clean water transfer at -15℃ to +80℃.
Resolves critical challenges of conventional horizontal fire pumps: excessive footprint, vibration/noise exceedance, seal leakage, and maintenance requiring pipeline disassembly.
Suitable for building fire network boosting, high-rise zoned supply, HVAC circulation, and industrial systems requiring GB 6245-2006 compliance, no-pipeline-removal maintenance, and reliable standby start-up.
Extended Service Life: Standard tungsten carbide dual mechanical seals + 2Cr13 stainless steel shaft resist wear, corrosion & cavitation. Design lifespan ≥15 years—over 40% longer than standard cast-iron single-stage fire pumps.
Significant Energy Savings: Advanced hydraulic model + high-efficiency motor matching achieve ≥78% efficiency at rated duty. Combined with VFD regulation for fire conditions, comprehensive system energy consumption drops by 20%–25% vs. traditional solutions.
Lower Maintenance Costs: Back-pull-out structure + top vent/pressure ports enables rotor/seal inspection without disconnecting inlet/outlet piping. Single technician completes maintenance within 1 hour, reducing labor costs by 50%.
Lightweight & Compact Design: Horizontal motor-pump direct coupling eliminates coupling guard & heavy baseplate. Overall weight reduced by ~18% for equivalent flow/head ratings, lowering floor load & lifting complexity.
Faster Installation: Pre-aligned flanges + anchor bolt positioning holes enable zero-cutting pipe connection on-site. Standard units reach commissioning readiness within 1.5 hours from unboxing, compressing installation cycle by 45%.
Core Fire Protection Applications: Hydrant network boosting, automatic sprinkler pressure stabilization, water mist system high-pressure supply for buildings, ensuring stable pressure & rapid response during fire emergencies to meet mandatory fire acceptance requirements.
Extended Building Water Applications: Zone boosting for high-rise/super high-rise buildings, long-distance water conveyance projects, municipal drainage networks, solving high-zone pressure insufficiency & long-distance transmission loss pain points.
HVAC Circulation Applications: Heating boiler hot/cold water circulation, AC cooling water boosting, terminal network pressure stabilization, with stable low-noise operation ensuring efficient heat exchange for HVAC systems.
Flexible Industrial Integration: Industrial process water supply, equipment cooling integration, bathroom hot water circulation, with modular design facilitating system integration & automated control.
Media Compatibility: Clean water or similar non-corrosive liquids. Insoluble solids ≤0.1% (by mass). Media temperature: -15℃ to +80℃ (5℉ to 176℉).Application Scenarios

Installation Key Points:
1.Mount pump horizontally on solid concrete foundation. Tighten anchor bolts symmetrically. Ensure shaft horizontal deviation ≤0.05 mm/m to prevent premature bearing wear from uneven loading.
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 to confirm smooth, friction-free rotation.
4.Open top vent valve to fill pump with media. Lock valve after confirming no air remains. Jog test to verify rotation (clockwise from motor end).
Commissioning Process: Prime & vent → Jog test for direction → No-load run 5 min → Slowly open discharge valve to rated duty → Record current/pressure/vibration/bearing temp data → Acceptance sign-off.
Request the “Horizontal Single-Stage Fire Pump Set Installation & Maintenance Manual” (PDF/English version) for complete dimensional drawings, flange specs, and commissioning logs.
Q1: How does back-pull-out design enable “maintenance without disconnecting pipes”?
After loosening rear cover bolts, motor + bracket + rotor assembly can be pulled out rearward as a unit. Core components (seals/bearings/impellers) are fully exposed for maintenance without disturbing inlet/outlet pipes.
Q2: How do tungsten carbide dual mechanical seals achieve leakage rate <0.01 mL/h?
Two seals in series (inner main + outer auxiliary) + oil-chamber lubrication/cooling. Tungsten carbide mating faces precision ≤0.001 mm. Tested leakage rate <0.01 mL/h, meeting clean workshop requirements.
Q3: How does ISO 1940 G6.3 dynamic balance ensure vibration <4.5 mm/s?
Impeller undergoes high-precision dynamic balance calibration, residual unbalance ≤4.5 g·mm/kg. Combined with short-span rigid shaft & heavy-duty self-aligning bearings, tested vibration <4.5 mm/s across all duties.
Q4: How to guarantee rapid response & stable pressure during fire emergencies?
Features low-inertia impeller + direct line-frequency start design, reaching rated RPM within 2 seconds upon fire alarm trigger. Combined with outlet slow-closing check valve, maintaining pipeline pressure fluctuation within ±0.05 MPa.
Q5: What customizations are needed for high-temperature media (>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 when ordering.
