ISG Series Single-Stage Vertical Pipeline Centrifugal Pump
The ISG Series single-stage vertical pipeline centrifugal pump is engineered through collaborative R&D with domestic pump experts, integrating advanced hydraulic models and performance parameters from the IS-type centrifugal pump. Building upon standard vertical pump design, this series offers versatile configurations for diverse applications. Derived models include specialized pumps for hot water (IRG/GRG), high-temperature fluids, corrosive chemicals (IHG), and petroleum products (YG). Featuring high efficiency, low noise, and reliable performance, this series delivers exceptional energy-saving operation.
Key Features
Compact Vertical Design
Identical inlet/outlet diameters aligned on a central axis enable valve-like pipeline installation.
Space-saving structure reduces infrastructure costs; optional protective cover allows outdoor use.
Stable & Quiet Operation
Impeller mounted directly on an extended motor shaft minimizes axial dimensions.
Optimized bearing configuration balances radial/axial loads, ensuring smooth operation with minimal vibration and noise.
Durable Sealing Solutions
Equipped with imported titanium alloy sealing rings or high-temperature-resistant mechanical seals.
Hard alloy materials enhance wear resistance, extending seal lifespan.
Easy Maintenance
Full rotor assembly can be disassembled without disturbing pipeline systems by removing coupling base nuts.
Flexible Configurations
Supports series/parallel operation to meet varying flow and head requirements.
Accommodates vertical or horizontal installation based on pipeline layout.
Primary Applications
ISG Standard Model
Transfers clean water or similar liquids (viscosity ≤ water).
Ideal for industrial/urban water supply, high-rise building pressurization, garden irrigation, firefighting systems, HVAC circulation, and sanitary hot water systems.
Max fluid temperature: 80°C.
IRG/GRG High-Temperature Models
Designed for boiler circulation, district heating, and industrial hot water systems.
IRG: ≤120°C; GRG: ≤240°C.
IHG Chemical-Resistant Model
Handles corrosive, non-abrasive liquids (e.g., acids, alkalis) in petrochemical, pharmaceutical, and food industries.
Temperature range: -20°C to +120°C.
YG Petroleum Model
Transports gasoline, diesel, kerosene, and other petroleum products.
Temperature range: -20°C to +120°C.
Operating Conditions
Pressure Limits
Suction pressure ≤1.0MPa; system pressure ≤1.6MPa (suction pressure + pump head).
For systems >1.6MPa, specify during ordering to enable cast steel construction.
Ambient Requirements
Temperature <40°C; humidity <95%.
Fluid Specifications
Solids content ≤0.1% by volume; particle size <0.2mm.
Note: For fluids with fine particles, specify "abrasion-resistant mechanical seals" when ordering.
Model Nomenclature
The model code indicates series variants (e.g., ISG, IRG, IHG, YG) tailored to specific media and temperature ranges.

I: Flow classification
A: The impeller is cut once (e.g., cut for reduced flow/pressure).
B: The impeller is cut twice (e.g., cut for reduced flow/pressure).
