1、 Main features of stainless steel horizontal centrifugal pump:
1. Smooth operation: The absolute concentricity of the pump shaft and excellent dynamic and static balance of the impeller ensure smooth operation without any vibration.
2. No leakage: The hard alloy seals made of different materials ensure that there is no leakage during the transportation of different media.
3. Low noise: The water pump supported by two low-noise bearings runs smoothly, with almost no noise except for weak motor noise.
4. Low failure rate: The structure is simple and reasonable, and the key parts are matched with international quality, greatly improving the fault free working time of the whole machine.
5. Easy maintenance: Replace seals and bearings, simple and convenient.
6. More land saving: The exit can be arranged in three directions: left, right, and up, which facilitates pipeline layout and installation, saving space.
The ISWH stainless steel horizontal centrifugal pump adopts the most advanced hydraulic model, designed according to the performance parameters of the IS single-stage single suction centrifugal pump and the unique structural combination of the vertical pump, and strictly designed and manufactured in accordance with international ISO 2858. The shaft seal of this product uses a hard alloy mechanical seal device, which has the characteristics of high efficiency, energy saving, reliable performance, and easy installation and use.

2、 Stainless steel horizontal centrifugal pump is mainly used for:
1. ISW horizontal clear water pump, used for conveying clear water and other liquids with physical and chemical properties similar to clear water, suitable for industrial and urban water supply and discharge
Water, high-rise building pressurized water supply, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC refrigeration cycle, bathroom and other cold and warm water circulation pressurization
Equipped with supporting equipment, the operating temperature is t ≤ 80 ℃.
2. ISWR horizontal hot water pump is widely used for boiler hot water pressurized circulation transportation in metallurgy, chemical industry, textile, papermaking, hotels and restaurants, etc
Urban heating system, iswr type, operating temperature t ≤ 120 ℃.
3. ISWH chemical stainless steel pipeline pump is used for conveying liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. It is suitable for petroleum and chemical industries
The operating temperature range for departments such as industry, metallurgy, power, papermaking, food and pharmaceuticals, and synthetic fibers is -20 ℃ to+120 ℃.
4. ISWB horizontal pipeline oil pump is used to transport oil products such as gasoline, kerosene, diesel, or flammable and explosive liquids. The temperature of the transported medium is
-20~+120 ℃.

5、 Preparation before starting stainless steel horizontal centrifugal pump:

1. Test whether the motor rotation is correct. When viewed from the top of the motor towards the pump, it rotates clockwise. The test time should be short to avoid causing mechanical tightness
Seal and wear.
2. Open the exhaust valve to fill the entire pump body with liquid, and then close the exhaust valve when it is full.
3. Check if all parts are normal.
4. Manually rotate the pump to allow lubricant to enter the mechanical seal end face.
5. High temperature type should be preheated first, with a heating rate of 50 ℃/hour to ensure uniform heating of all parts.
start:
1. Fully open the inlet valve.
2. Close the valve of the discharge pipeline.
3. Start the motor and observe if the pump is running correctly.
4. Adjust the opening of the outlet valve to the desired operating conditions. If the user has a flow meter or pressure gauge installed at the pump outlet, the outlet should be adjusted by adjusting it
The valve opening allows the pump to operate at the rated point listed in the performance parameter table. If the user has a flow or pressure gauge installed at the pump outlet, it should
By adjusting the opening of the outlet valve and measuring the motor current of the pump, the motor can operate within the rated current, otherwise it will cause the pump to overload
Run (i.e. high current operation) until the motor burns out. The opening size of the outlet valve that is adjusted correctly is related to the working conditions of the pipeline.
5. Check the leakage of the shaft seal. Normally, the mechanical seal leakage should be less than 3 drops per minute.
6. Check that the temperature rise at the motor and bearings is ≤ 70 ℃.
parking:
1. The high-temperature type should first cool down, with a cooling rate of less than 10 ℃/minute, and then lower the temperature to below 80 ℃ before parking.
2. Close the valve of the discharge pipeline.
3. Stop the motor.
4. Close the inlet valve.
5. If parking for a long time, the liquid in the pump should be drained completely.
Reasons and Solutions for Malfunctions of Stainless Steel Chemical Pipeline Pumps

6、 Precautions for stainless steel horizontal centrifugal pump:
1. Water pumps below 7.5kw can be equipped with seismic isolation pads and installed directly on the foundation; When the power is above 7.5kw, it can be installed directly with the casting foundation, or our unit can use the IS connection plate to install the shock absorber. The installation method of the shock absorber is the same as that of the shock absorber matched with the ISG pump, and the size of the shock absorber is the same as that of the same specification water pump in the ISG pump train.
2. Before installation, check if the fasteners of the unit are loose and if there are any foreign objects blocking the flow channel of the pump body to avoid damaging the blades during the operation of the water pump
Wheel and pump body.
3. The weight of the pipeline should not be added to the water pump during installation to avoid deformation of the pump.
4. The foundation bolts must be tightened during installation to avoid the impact of vibration on pump performance during start-up.
5. After installation, the pump shaft should be moved, and there should be no friction sound or jamming phenomenon of the impeller. Otherwise, the pump should be disassembled to check the cause.
6. There are two types of pump installation: rigid connection installation and flexible connection installation (see connection method).
7. For the convenience of maintenance and safety of use, install one regulating valve on each inlet and outlet pipeline of the pump, and install one near the pump outlet
Only pressure gauges are used to ensure operation within the rated head and flow range, ensuring the normal operation of the pump and increasing its service life.
