Engineered with a vertical direct-coupled structure and modern optimized hydraulic model, delivering a compact, high-efficiency, low-noise inline fluid transport solution for municipal, industrial, and HVAC systems.
Precisely deployed for high-rise water boosting, fire pressure stabilization, boiler circulation, chemical processes, and noise-sensitive environments, ensuring stable transport of clean water and similar non-corrosive media.
Unlike traditional horizontal centrifugal pumps, the ISG series features a coaxial inline design enabling direct pipeline embedding without retrofitting. This reduces system energy consumption by 20%, limits operating noise to ≤60 dB(A), and cuts footprint by 50%, setting a new benchmark for single-stage inline pumps..
Extended Service Life: Standard carbide/SiC mechanical seals + 2Cr13 stainless steel shaft resist wear, corrosion & cavitation. Design lifespan ≥15 years—over 40% longer than standard cast-iron single-stage pumps.
Significant Energy Savings: CFD-optimized hydraulic model + IE3 motor matching achieve ≥80% efficiency at rated duty. Comprehensive system energy consumption drops by 20%–30% vs. traditional solutions.
Lower Maintenance Costs: Motor-pump coaxial direct-coupling (zero alignment) + top fill/vent ports enable routine maintenance without disconnecting inlet/outlet piping. Single technician completes service within 1 hour, reducing labor costs by 50%.
Lightweight & Compact Design: Integrated cast pump body eliminates independent coupling & heavy baseplate. Overall weight reduced by ~25% for equivalent flow/head ratings, lowering floor load requirements.
Faster Installation: Standardized inlet/outlet flanges + quick-connect design require zero on-site pipe cutting. Standard units complete positioning-to-commissioning within 1.5 hours, compressing installation cycle by 45%.
Municipal & Building Water: Municipal drainage networks, high-rise domestic water boosting, fire system pipeline pressure stabilization, HVAC circulating water transport.
Industrial & Energy Processes: Boiler feedwater, urban central heating systems, chemical/pharmaceutical/metallurgical/power industrial fluid transport.
Petrochemical & Special Conditions: Oil storage & transportation, gas station fuel supply systems, hazardous environment fluid dispatch (chemical/dyeing/pharma).
Quiet & High-Standard Venues: Hospitals, premium hotels, Grade-A offices requiring strict noise & vibration control for indoor circulation systems.
Media Compatibility: Clean water or similar non-corrosive liquids. Solid content ≤0.1% (vol), particle size <0.2 mm.

Pre-Installation Checks: Verify foundation flatness ≤2 mm/m, maintain ≥400 mm clearance. Confirm max system pressure ≤1.6 MPa, solids <0.2 mm, ambient temp <40℃, humidity <95% (non-condensing).
Installation Key Points:
1.Mount pump vertically on solid foundation. Inlet/outlet flanges must align naturally. Never use pump body to absorb pipe stress. Install flexible rubber joints.
2.Provide independent pipe supports for inlet/outlet. Never transfer pipe weight to pump flanges to prevent casing deformation & seal failure.
3.Motor junction box faces outward/upward. 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 to calculate & verify max system pressure of 1.6 MPa?
Working Pressure = Suction Pressure + Shut-off Head Pressure. Every unit undergoes 2.5 MPa (1.5× rated) hydrostatic test for 5 min at factory, guaranteeing zero casing/flange leakage.
Q2: How does coaxial direct-coupling prevent seal misalignment from thermal pipe expansion?
Precision alignment completed at factory. Flexible joints/expansion joints must be installed at inlet/outlet to absorb axial/radial pipe stress. Rigid connection is strictly prohibited.
Q3: How to configure for media containing fine particles (<0.2 mm)?
Standard carbide seals suit clean water. Specify during ordering for particulate media. We upgrade to wear-resistant SiC mating faces & recommend upstream Y-strainers.
Q4: How to ensure CCCF & GB 50974 compliance in fire applications?
Must use CCCF-certified fire-rated unit, connect to dedicated fire power supply, and equip control cabinet with dual-circuit power & auto-inspection. Weekly auto-test required with instant fault alarm.
Q5: How to quickly troubleshoot overcurrent or abnormal vibration during operation?
Stop immediately & check: ① Verify head isn’t below rated (causing high-flow overload); ② Check loose anchor bolts or pipe stress transmission; ③ Measure 3-phase current imbalance ≤5%.
