Product Introduction
The ISW, ISWR, and ISWH horizontal single-stage single suction pipeline pump systems are optimized using hydraulic models based on the performance parameters of IS and IR centrifugal pumps, following the ISO2858 standard. It is an ideal new generation of high-efficiency and energy-saving horizontal pump product.

Product Features
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. Drip proof: 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 under 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 high-quality matching is used for key parts, greatly improving the fault free working time of the whole machine.
5. Easy to maintain: replace seals and bearings, simple and convenient.
6. More land saving: The exit can be arranged in three directions: left, right, and up, which is convenient for pipeline layout and installation, saving space.
7. ISW horizontal pipeline centrifugal pump is used for conveying clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply, high-rise building pressurized water supply, garden sprinkler irrigation, fire protection pressurization, long-distance transportation, HVAC refrigeration cycle, bathroom and other cold and warm water circulation pressurization and equipment matching. The operating temperature T ≤ 80 ℃.
8. The ISWR horizontal hot water pipeline centrifugal pump is widely used in metallurgy, chemical industry, textile, papermaking, as well as hotels, restaurants, and other boiler hot water pressurized circulation transportation and urban heating systems. The ISWR type uses a temperature T ≤ 120 ℃.
9. ISWH horizontal chemical 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 industries such as petroleum, chemical, metallurgical, power, papermaking, food and pharmaceuticals, and synthetic fibers. The operating temperature ranges from -20 ℃ to+120 ℃.
10. ISWB horizontal pipeline oil pump is used to transport oil products such as gasoline, kerosene, diesel, or flammable and late explosive liquids. The temperature of the transported medium is -20 ℃ to+120 ℃.

application
1. The ISW pump is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire boosting, long-distance water supply, HVAC refrigeration cycle, bathroom warm water cycle boosting, as well as supporting various water supply equipment and boilers. Used for conveying clean water or other liquids with physical or chemical properties similar to clean water, with a usage temperature not exceeding 85 degrees Celsius℃.
2. The ISWR pump is suitable for metallurgy, chemical industry, textile, wood processing, papermaking, as well as restaurants, bathrooms, hotels, boiler hot water boosting circulation, and urban housing heating circulation, with a usage temperature not exceeding 120 ℃.
3. The ISWD pump is suitable for situations where low environmental noise is required, and the operating temperature should not exceed 100 ℃.

Conditions of Use
1. The suction pressure is ≤ 1.0Mpa, or the working pressure of the pump system is ≤ 1.6Mpa, that is, the pump suction inlet pressure+pump head is ≤ 1.6Mpa, and the pump static pressure test pressure is 2.5Mpa. Please specify the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6Mpa, it should be separately stated when ordering, so that the overcurrent components and connecting parts of the pump can be made of cast steel materials during manufacturing.
2. Environmental temperature<40 ℃, relative humidity<95%.
3. The volume content of solid particles in the conveyed medium shall not exceed 0.1% of the unit volume, and the particle size shall be less than 0.2mm
Note: If the medium used is with small particles, please specify when ordering so that wear-resistant mechanical seals can be used.

scope of application
1. The high working pressure of the system is 1.6MPa, which means that the pump suction pressure+pump head is ≤ 1.6MPa (if the working pressure of the pump system is greater than 1.6MPa, it should be separately specified when ordering, so that cast steel can be used in the manufacturing of the pump's overcurrent components and connecting components)
2. The conveying medium is clear water or other liquids with physical and chemical properties similar to clear water.
3. Environmental temperature ≤ 40 ℃, altitude ≤ 1000m, relative humidity ≤ 95%.

Installation instructions
1. Before installation, carefully check whether there are any hard objects inside the pump body to avoid damaging the impeller and pump body during operation.
2. During installation, pipeline management should not be added to the pump to prevent deformation and affect normal operation.
3. Tighten the anchor bolts to prevent vibration during start-up from affecting the performance of the pump.
4. Install regulating valves on the inlet and outlet pipelines of the pump, and install pressure gauges near the pump outlet to control the pump's operation within rated conditions and ensure its normal use.
5. If a check valve is installed in the discharge pipeline, it should be installed outside the gate valve.
6. The installation methods of pumps are divided into rigid connection installation and flexible connection installation.

Start and Stop
（1） Preparation before starting
1. Pull and rotate the motor fan blades 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. The mechanical seal leakage should be ≤ 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 imported pipeline must be filled with liquid, and the pump is prohibited from running for a long time in a cavitation state.
2. Regularly check the motor current value and ensure it does not exceed the rated current of the motor.
3. 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, and vulnerable parts can be replaced if necessary. 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.
4. The allowable deviation for seal leakage is 3 drops/minute, otherwise maintenance should be carried out.
