Product Description
Model Code Explanation
Product Introduction
ISGB vertical easy-disassembly pipeline clean water pump is a newly developed vertical centrifugal pump based on the IS single-stage single-suction centrifugal pump and the ISG pipeline clean water pump, combined with our company’s years of manufacturing experience and valuable user feedback. This series features a novel structure and advanced comprehensive performance that meets all required standards. The products are designed and manufactured strictly according to the international standard ISO2858.
ISGB vertical easy-disassembly pipeline clean water pump adopts a bold overall structural breakthrough. The pump shaft uses an independent support body, effectively solving the deficiency of extended shafts relying on motor bearings in ISG and ISW pumps. The impeller and pump body are designed with modern hydraulic models, eliminating axial and radial forces of vertical pumps. As a result, the bearings on both the pump shaft and the motor endure only minimal axial and radial forces. The pump uses a national standard motor and an easy-disassembly structure, making it convenient to replace bearings, mechanical seals, impellers, and other wearing parts of large-power pumps.
ISGB vertical easy-disassembly pipeline clean water pump offers irreplaceable advantages such as smoother operation, longer service life, easier matching, and simpler maintenance. It is an ideal replacement for ISG pipeline pumps, IS single-stage single-suction centrifugal pumps, and S-type double-suction pumps.
Product Features
1. The pump shaft and motor shaft adopt a rigid connection, resulting in low vibration and low noise.
2. The pump inlet and outlet diameters are identical, allowing installation at any position in the pipeline like a valve. The pump is equipped with a base for easy and stable installation.
3. The pump shaft has an independent support point, ensuring reliable motor bearing operation.
4. The mechanical seal uses a special forced-circulation structure that is not restricted by rotation direction, providing reliable operation and long service life.
5. The unique installation structure significantly reduces the pump footprint, saving 30%–50% of construction investment.
6. The optimized design ensures leak-free, long-life operation and reduces operational management costs by 40%–70%.
7. Driven by a motor through a coupling, the pump rotates clockwise when viewed from the drive end.
Product Applications
1. ISGB vertical easy-disassembly pipeline clean water pumps are suitable for non-corrosive chilled water, hot water, and systems such as heating, domestic water, chilled water circulation, and irrigation systems.
2. IHGB and YGB series pumps are suitable for petroleum, chemical industry, metallurgy, electric power, paper-making, food processing, pharmaceuticals, and synthetic fiber industries.
Operating Conditions
1. Medium temperature: T = -20°C to +120°C;
2. Ambient temperature: T ≤ 40°C; relative humidity ≤ 95%.

Installation Instructions
1. During installation, the weight of the pipeline should not be supported by the pump. Each pipeline must have its own support to avoid pump deformation, which may affect performance and service life.
2. For convenient maintenance and safe operation, a regulating valve should be installed on both the inlet and outlet pipelines of the pump, and a pressure gauge should be installed near the pump outlet. This ensures the pump operates within the rated head and flow range, extending its service life.
3. When the pump is used under suction conditions, a foot valve must be installed. The inlet pipeline should have as few bends as possible, and must not have any water leakage or air leakage.
4. After installation, rotate the pump shaft manually. The impeller should not produce friction or jamming. Otherwise, disassemble the pump to check the cause.
5. Pump installation methods are divided into two types: rigid connection and flexible connection.

Preparations
(I) Preparations Before Starting
1. Rotate the pump shaft or pump coupling by hand; the impeller should rotate freely without friction or jamming.
2. Open the inlet valve and open the exhaust valve to allow liquid to fill the entire pump chamber, then close the exhaust valve.
3. Rotate the pump shaft manually to let the lubricating fluid enter the mechanical seal surfaces.
4. Jog the motor to confirm whether the rotation direction is correct.
(II) Start-Up and Operation
1. Fully open the inlet valve and close the outlet pipeline valve.
2. Switch on the power supply. After the pump reaches normal speed, gradually open the outlet valve and adjust to the required operating conditions.
3. Observe the instrument readings. Check shaft seal leakage (normal mechanical seal leakage ≤ 3 drops/min). Ensure the temperature rise of the motor and bearings ≤ 70°C. If any abnormal condition occurs, take corrective action immediately.
(III) Shutdown
1. Gradually close the outlet pipeline valve and cut off the power supply.
2. Close the inlet valve.
3. If the ambient temperature is below 0°C, drain the liquid inside the pump to prevent freezing damage.
4. For long-term shutdown, disassemble the pump, clean it, and store it properly.
OEM & Custom Solutions
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.
