Product Introduction
The ISGB vertical detachable pipeline pump is a structurally novel detachable vertical centrifugal pump developed based on the IS single-stage single suction centrifugal pump and ISG pipeline clean water pump, combined with our company's years of production experience and the valuable experience of our customers. The comprehensive performance of this series of products has reached an advanced level, and all indicators are qualified. This series of products is designed and manufactured strictly in accordance with the international standard ISO2858.
The ISGB vertical detachable pipeline pump has made bold breakthroughs in overall design. The pump shaft adopts an independent support body, solving the shortcomings of the original ISG and ISW pump extension shafts supported by motor bearings. The impeller and pump body are designed and manufactured using modern hydraulic models, eliminating the axial and radial forces of the vertical pump, so that the bearings at the pump shaft and motor bearings only receive weak axial and radial forces. The motor adopts a national standard motor, and the entire pump adopts a detachable structure, solving the problem of inconvenient replacement of vulnerable parts such as bearings, mechanical seals, impellers, etc. of high-power water pumps.
The ISGB vertical detachable pipeline pump has irreplaceable advantages such as smoother operation, longer service life, more convenient matching, and easier maintenance. It is an ideal product to replace conventional centrifugal pumps such as ISG pipeline water pumps, IS single-stage single suction centrifugal pumps, S-type double suction pumps, etc.

Product Features
1. The pump shaft and motor shaft are rigidly connected, with low vibration and noise;
2. The inlet and outlet diameters of the pump are the same, and it can be installed at any position in the pipeline like a cold door. It is also equipped with a chassis, making the pump installation simple and stable;
3. The pump shaft has independently produced support points, ensuring reliable operation of the motor bearings;
4. Using a special structure mechanical seal with forced circulation that is not restricted by steering, it operates reliably and has a long service life;
5. The unique installation structure greatly reduces the footprint of the pump, saving 30% to 50% of construction investment;
6. The perfect design ensures that the pump operates without leakage and has a long service life, saving 40% to 70% of operating management costs.
7. Through the motor coupling, the pump is driven by the motor, and when viewed from the transmission end, the pump rotates clockwise.

application
1. ISGB vertical detachable pipeline pump is used for non corrosive cold and hot water in heating, sanitary water, chilled water systems, and irrigation devices.
2. IHGB and YGB pumps are used in sectors such as petroleum, chemical, metallurgical, power, papermaking, food, pharmaceuticals, and synthetic fibers.

Conditions of Use
1. Medium temperature: T=-20 ℃~+120 ℃;

Installation instructions
1. The weight of the pipeline should not be added to the water pump during installation, and there should be separate supporting bodies to avoid deformation of the pump and affecting its operational performance and service life.
2. For the convenience of maintenance and safety of use, a regulating valve is installed on the inlet and outlet pipelines of the pump, and a pressure gauge is installed near the pump outlet to ensure operation within the rated head and flow range, thereby increasing the service life of the water pump.
3. Pumps used in suction applications should be equipped with bottom valves, and the inlet pipeline should not have too many bends, and there should be no water or air leakage.
4. After installation, the pump shaft should be moved, and there should be no friction or jamming of the impeller. Otherwise, the pump should be disassembled to check the cause.
5. The installation methods of pumps are divided into two types: rigid connection and flexible connection.

Start and Stop
（1） Preparation before starting
1. Pull the pump shaft or pump coupling by hand, and the impeller should have no jamming or grinding phenomenon, and rotate flexibly.
2. Open the inlet valve, open the exhaust valve to fill the entire pump chamber with liquid, and then close the exhaust valve.
3. Manually rotate the pump shaft to allow lubricant to enter the mechanical seal end face.
4. Tap the motor to confirm if the steering is correct.
（2） Start up and operation
1. Fully open the inlet valve and close the outlet pipeline valve.
2. Connect the power supply, gradually open the valve on the discharge pipeline when the pump reaches normal speed, and adjust it to the desired working condition.
3. Pay attention to the instrument readings and check if the shaft seal leakage is normal. When the mechanical seal leakage is ≤ 3 drops/minute, check if the temperature rise at the motor and bearing is ≤ 70 ℃. If any abnormal situation is found, it should be dealt with in a timely manner.
（3） Parking
1. Gradually close the valve of the discharge pipeline and cut off the power supply.
2. Close the inlet valve.
3. If the ambient temperature is below 0 ℃, the liquid inside the pump should be drained to prevent freezing and cracking.
4. If the pump is not in use for a long time, it should be disassembled, cleaned, and kept under management.

maintenance
（1） Maintenance and upkeep during operation
1. The inlet pipeline must be highly sealed
2. Do not operate the pump for a long time under cavitation conditions.
3. Prohibit the pump from operating at high flow rates and the motor from running at overcurrent for extended periods of time.
4. Regularly check the motor current value during pump operation and ensure it does not exceed the rated current of the motor.
5. The pump should be supervised by a dedicated person during operation to prevent accidents.
6. Oil should be added to the bearings every 500 hours of pump operation. The motor power greater than 11KW is equipped with a refueling device, which can be directly injected with a high-pressure oil gun to ensure excellent bearing lubrication.
7. After long-term operation of the pump, if the noise and vibration of the unit increase due to mechanical wear, it should be stopped for inspection. If necessary, vulnerable parts and bearings can be replaced. The overhaul period of the unit is generally one year.
（2） Mechanical seal maintenance and upkeep
1. Mechanical seal lubrication should be clean and free of solid particles.
2. Mechanical seals are strictly prohibited from working under dry grinding conditions.
3. Before starting, the pump (motor) should be turned a few times to avoid sudden starting causing damage to the sealing ring.
