Product Overview
The ISGB Vertical Removable Line Centrifugal Clean Water Pump is a newly developed vertical centrifugal pump based on the IS single-stage end-suction centrifugal pump and the ISG online cleaning water pump design, in compliance with the ISO 2858 international standard. By integrating years of manufacturing experience and extensive user feedback, this pump series adopts an optimized structural design and advanced hydraulic performance. It is suitable for various pipeline applications, ensuring stable performance and reliable flow under a wide range of working conditions.
Model Designation

Key Features
-
The rigid coupling design between the pump shaft and the motor shaft ensures low vibration and low noise operation.
-
The independent shaft support structure effectively prevents hydraulic loads from being transmitted to the motor bearings, extending the motor’s service life.
-
The forced circulation mechanical seal design is not affected by rotation direction, providing high reliability and long service life.
-
The easy-to-disassemble structure facilitates bearing, mechanical seal, and impeller replacement, reducing maintenance costs.
-
The compact vertical design saves approximately 30% to 50% of installation space, reducing construction costs.
-
Optimized sealing and structural design ensure long-term leak-free operation, reducing operating and maintenance costs.
Engineering Overview
The ISGB pump adopts an independent shaft support, eliminating the structural limitations of traditional ISG and ISW pumps. Through modern hydraulic design, the axial and radial forces generated during operation are effectively balanced, ensuring that the pump shaft and motor bearings are subjected to minimal load, enhancing the system’s operational stability and reliability.
Typical Applications
The ISGB Vertical Removable Line Centrifugal Clean Water Pump is suitable for the following applications:
-
Engineering pipeline systems
-
Various building fire water supply systems
-
Automatic sprinkler fire extinguishing systems

Installation Guide
-
Pipeline Support: The weight of the pipeline should not be borne by the pump. Each pipeline should have its own support system to prevent pump deformation, which may affect performance and shorten its service life.
-
Maintenance and Safety: To facilitate maintenance and ensure safe operation, install a regulating valve on both the inlet and outlet pipelines of the pump. Additionally, a pressure gauge should be placed near the pump outlet to monitor operating conditions. This ensures the pump runs within its rated head and flow range, thereby extending its service life.
-
Suction Conditions: When the pump operates under suction conditions, a foot valve must be installed. The inlet pipeline should be designed with as few bends as possible, and there must be no water or air leakage.
-
Pre-Operation Check: After installation, manually rotate the pump shaft. The impeller should rotate smoothly without friction or obstruction. If any resistance is detected, disassemble the pump to identify and resolve the cause.
-
Connection Methods: There are two installation methods for the pump: rigid connection and flexible connection. Choose the appropriate method based on the installation environment and system requirements.

Operating Manual
Preparations
(I) Preparations Before Starting
-
Rotate the pump shaft or pump coupling by hand; the impeller should rotate smoothly without friction or obstruction.
-
Open the inlet valve and the exhaust valve to allow liquid to fill the pump chamber completely, then close the exhaust valve.
-
Manually rotate the pump shaft to allow lubricating fluid to enter the mechanical seal surfaces.
-
Jog the motor to check whether the rotation direction is correct.
(II) Start-Up and Operation
-
Fully open the inlet valve and close the outlet pipeline valve.
-
Switch on the power supply. Once the pump reaches normal speed, gradually open the outlet valve and adjust to the required operating conditions.
-
Monitor instrument readings. Check for shaft seal leakage (normal mechanical seal leakage should not exceed 3 drops/min). Ensure that the temperature rise of the motor and bearings does not exceed 70°C. If any abnormal conditions arise, take corrective action immediately.
(III) Shutdown
-
Gradually close the outlet pipeline valve and disconnect the power supply.
-
Close the inlet valve.
-
If the ambient temperature is below 0°C, drain the liquid inside the pump to prevent freezing and potential damage.
-
For long-term shutdown, disassemble the pump, clean it, and store it properly.
OEM & Custom
We provide OEM/ODM manufacturing with options for stainless steel, cast iron, or duplex steel materials, customized voltage (220V/415V/460V), and explosion-proof motors. Optional base-mounted designs and flange standards (DIN/ANSI/JIS) are available. All pumps comply with ISO9001 and CE certification for export markets.
FAQs
