Product Parameters
Application Conditions and Model Significance for ISG Vertical Single-Stage Single-Suction Pipeline Centrifugal Pumps:
1. The suction pressure shall be ≤1.0 MPa, or the maximum working pressure of the pump system shall be ≤1.6 MPa—i.e., the suction pressure plus the pump head shall not exceed 1.6 MPa. The hydrostatic test pressure for the pump is 2.5 MPa. Please specify the system’s working pressure when placing your order. If the pump system’s working pressure exceeds 1.6 MPa, this should be explicitly stated at the time of ordering so that the pump’s flow passages and connecting parts can be made of cast steel during manufacturing.
2. Ambient temperature < 40℃, relative humidity < 95%.
3. The volume content of solid particles in the conveyed medium shall not exceed 0.1% per unit volume, and the particle size shall be less than 0.2 mm.
Note: If the medium contains fine particles, please specify this when placing your order so that the manufacturer can equip the pump with a wear-resistant mechanical seal.
Main applications of the ISG vertical single-stage single-suction pipeline centrifugal pump:
1. The ISG vertical pipeline pump is designed for conveying clean water and other liquids whose physical and chemical properties are similar to those of clean water. It is suitable for industrial and municipal water supply and drainage, pressurized water delivery in high-rise buildings, landscape irrigation, fire-fighting boosting, long-distance water transmission, HVAC and refrigeration circulation, cold and hot water circulation boosting in bathrooms, and equipment integration. The operating temperature is T < 80℃.
2. The IRG vertical hot-water pump is suitable for boosting and circulating high-temperature hot water in boilers used in metallurgy, chemical industry, textile, wood processing, papermaking, as well as in hotels, bathhouses, and guesthouses. It can also be used for heating circulation in urban residential buildings. The operating temperature is below 120℃.
3. The GRG vertical high-temperature centrifugal pump is widely used for boosting and circulating high-temperature hot water in boilers at power plants, metallurgical facilities, chemical plants, textile mills, paper mills, as well as in hotels, bathhouses, and guesthouses. It is also suitable for circulating heating systems in urban residential buildings. The pump’s operating temperature is below 240℃.
4. The IHG vertical stainless steel pipeline centrifugal pump is designed for conveying liquids that are free of solid particles, corrosive, and have a viscosity similar to water. It is suitable for use in industries such as petroleum, chemical engineering, metallurgy, power generation, papermaking, food and pharmaceuticals, and synthetic fibers.

Structural Diagram and Features of the ISG Vertical Single-Stage Single-Suction Pipeline Centrifugal Pump:
1. The ISG vertical pipeline pump features a vertical design with identical inlet and outlet diameters located on the same centerline. It can be installed in pipelines just like a valve. The pump boasts a compact and aesthetically pleasing appearance, occupies a small footprint, and requires low initial construction investment. With the addition of a protective cover, it can even be used outdoors.
2. The impeller is directly mounted on the motor’s extended shaft, resulting in a short axial dimension and a compact structure. The pump and motor bearings are arranged reasonably, effectively balancing the radial and axial loads generated during pump operation, thereby ensuring smooth pump operation with minimal vibration and low noise.
3. The shaft seal employs either a mechanical seal or a mechanical seal combination, featuring imported titanium alloy sealing rings, medium-sized high-temperature-resistant mechanical seals, and seals made of hard alloy materials that offer excellent wear resistance, thereby effectively extending the service life of the mechanical seal.
4. Easy to install and maintain—no need to disassemble the pipeline system; simply remove the pump coupling base nut to extract the entire rotor assembly.
5. The ISG vertical pipeline centrifugal pump can adopt series or parallel operation modes according to the specific requirements of flow rate and head.
6. The ISG vertical pipeline centrifugal pump can be installed either vertically or horizontally according to the requirements of the piping layout.
Pipeline Pump Preparation, Startup, and Shutdown:
I. Preparations Before Starting:
1. Verify that the motor rotation direction is correct—when viewed from the top of the motor toward the pump, the rotation should be clockwise. The test duration should be brief to avoid dry friction and wear on the mechanical seal.
2. Open the exhaust valve to allow the liquid to fill the entire pump body. Once full, close the exhaust valve.
3. Before starting the ISG single-stage pipeline pump, check whether all components are functioning properly.
4. Manually turn the pump to allow lubricant to enter the mechanical seal faces.
5. For high-temperature applications, preheating is required first, with a heating rate of 50°C per hour, to ensure uniform heating throughout all components.
II. Starting:
1. Fully open the inlet valve.
2. When starting a vertical centrifugal pump, close the discharge pipeline valve.
3. Motor: Observe whether the pump is operating correctly.
4. Check the shaft seal for leaks. Under normal conditions, mechanical seal leakage should be less than 3 drops per minute.
5. Check that the temperature rise at the motor and bearing locations is ≤70℃.
6. Adjust the opening of the outlet valve to achieve the desired operating conditions. If the user has installed a flow meter or pressure gauge at the pump outlet, adjust the outlet valve opening so that the pump operates at the rated point specified in the performance parameter table. Similarly, if the user has installed a flow meter or pressure gauge at the pump outlet, adjust the outlet valve opening and monitor the motor current of the pump to ensure that the motor operates within its rated current range. Otherwise, the pump may run under overload conditions (i.e., with excessive current), potentially leading to motor burnout. The appropriate opening degree of the adjusted outlet valve depends on both the size of the valve and the specific pipeline conditions.
3. Parking:
1. Close the discharge pipeline valve.
2. Stop the motor.
3. When shutting down a vertical centrifugal pump, close the inlet valve.
4. If the pump is to be parked for an extended period, the liquid inside the pump should be drained completely.
5. For high-temperature types, first cool down; cooling rate:
Maintenance during operation and mechanical seal maintenance:
I. Maintenance during operation:
1. The inlet pipeline must be completely filled with liquid; pumps are prohibited from operating for extended periods under cavitation conditions.
2. The vertical pipeline centrifugal pump should have its motor current checked regularly, and the current must not exceed the motor’s rated current.
3. After prolonged operation, if the unit’s noise and vibration increase due to mechanical wear, it should be stopped for inspection. If necessary, worn parts and bearings can be replaced. The general overhaul period for the unit is one year.
4. During operation, a dedicated person should be assigned to manage and maintain the equipment to prevent accidents.
5. The bearings should be lubricated every 500 operating hours. Motors with a power rating greater than 11 kW are equipped with a lubrication device that allows direct injection using a high-pressure grease gun, ensuring excellent bearing lubrication.
II. Mechanical Seal Maintenance:
1. When using the pump, the mechanical seal lubricant should be clean and free of solid particles.
2. When using a vertical centrifugal pump, it is strictly prohibited for the mechanical seal to operate under dry-running conditions.
3. Before starting the pump, first turn the pump (and motor) several revolutions by hand to prevent sudden start-up from causing damage or fracture to the graphite components.
4. The permissible leakage rate for the seal is 3 drops per minute. Otherwise, an inspection should be conducted.

Q
What is your typical delivery time?
A
Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。
Q
Do you have centrifugal pumps in stock?
A
Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.
Q
What information should I provide when requesting a quote?
A
Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.
If you are not sure, don't worry, our business managers will assist you in determining this.
Q
What products do you mainly produce?
A
Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.
Q
Why is it so slow to get a price quote?
A
Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
