Product Overview
The ISG Single-Stage Single-Suction Clean Water Pump is an energy-efficient vertical centrifugal pump, developed based on the performance parameters of the IS single-stage centrifugal pump and pipeline pump. It is designed and manufactured in compliance with ISO 2858 and JB/T 53058-93 standards, with a wide range of applications. The pump is suitable for transporting clean water and other liquids with similar physical and chemical properties to water, widely used in industrial and municipal water supply systems.
Model Designation
Key Features
-
High-efficiency hydraulic design ensures a wide performance range.
-
Low vibration and noise, with optimized bearing configuration for smooth operation.
-
Precision mechanical seal options, including titanium alloy sealing rings and hard carbide materials, provide reliable sealing performance and extend service life.
-
Compact vertical design saves space and is suitable for installations in confined spaces.
-
Easy to maintain, with quick rotor component replacement without the need to dismantle pipelines, reducing downtime.
Engineering Overview
The ISG series features a modular design that can be optimized for different media, flow rates, and pressure requirements. The structure and material selection of the pump ensure reliability in high-temperature, corrosive liquids, or oil transport. By replacing seals, bearings, and cooling systems, the pump can be adapted for hot water, high-temperature water, and chemical medium transport.
Typical Applications
The ISG pump is widely used in the following areas:
-
Industrial and municipal water supply systems.
-
High-rise building water pressure boosting systems.
-
Landscape irrigation and fire-fighting systems.
-
Auxiliary equipment and industrial equipment water supply systems.
-
Hot water and chemical liquid circulation systems.
System Configuration
The ISG series pump primarily includes the following components:
-
Suction casing and outer shell.
-
Rotating assembly (impeller, bearing system, mechanical seal).
-
Shaft sealing system: including mechanical seals or combined seals, titanium alloy sealing rings.
-
Installation accessories: foundation fastening components, protective cover (optional).
Components and Supply
The key components of the ISG pump system include:
-
Pump casing: vertical structure with coaxial inlet and outlet.
-
Rotating assembly: impeller and shaft sleeve, with grid-type bearings, easy to disassemble.
-
Shaft sealing system: includes titanium alloy sealing rings and fire-resistant mechanical seal components.
Technical Services
The ISG series pump provides comprehensive technical support, including installation, commissioning, and maintenance services. We ensure the long-term efficient operation of the equipment by providing detailed operation manuals and technical support.
Operating Conditions
-
Inlet pressure: ≤1.0 MPa.
-
Maximum operating pressure: 1.6 MPa (inlet pressure + pump head ≤ 1.6 MPa).
-
Applicable liquid: clean water or similar liquid without solid particles or fibers.
-
Maximum liquid temperature: ≤110°C.
-
Ambient temperature: ≤40°C, humidity: ≤95%.
Service Conditions
-
The packing seal leakage should be properly adjusted, allowing slight dripping for cooling and sealing.
-
When the liquid contains fine particles, the order must specify this so that wear-resistant mechanical seals can be selected.
Protection Functions
The ISG pump is equipped with overload protection, overpressure protection, and dry-running prevention systems to ensure stable operation under extreme conditions and prevent damage.
Selection Criteria
When selecting the ISG pump, factors such as medium type, required flow, head requirements, and installation space must be considered to ensure optimal efficiency and long-term stability.
