The ISW horizontal centrifugal pump adopts an advanced hydraulic model, designed based on the performance parameters of the IS type centrifugal pump and the unique structural combination of the horizontal centrifugal pump, and strictly designed and manufactured in accordance with international ISO 2858. The single-stage single suction centrifugal pump shaft seal uses a hard alloy mechanical seal device, which has the characteristics of high efficiency, energy saving, reliable performance, and easy installation and use. FEATURES 1. Single stage centrifugal pump runs smoothly: The absolute concentricity of the pump shaft and excellent dynamic and static balance of the impeller ensure smooth operation without any vibration.
2. Single stage single suction centrifugal pump is leak proof: hard alloy seals made of different materials ensure that there is no leakage during the transportation of different media.
3. Single stage single suction centrifugal pump has 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 of single-stage single suction centrifugal pump: The structure is simple and reasonable, and the key parts are matched with international first-class quality, greatly improving the fault free working time of the whole machine.
5. ISW water pump maintenance is convenient: replacing seals and bearings is easy and convenient.
6. Single stage single suction centrifugal pump takes up more space: the outlet can be arranged in three directions: left, right, and up, which facilitates pipeline layout and installation, saving space. Purpose 1. ISW water pump is used for transporting clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, 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 and equipment matching. The operating temperature is t ≤ 80 ℃.
2. The ISWR hot water centrifugal pump is widely used in boiler hot water pressurized circulation transportation and urban heating systems such as metallurgy, chemical industry, textile, papermaking, hotels and restaurants. The ISWR type is suitable for use at a temperature of t ≤ 120 ℃.
3. The ISWH horizontal chemical pipeline pump is designed for transporting 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, with an operating temperature range of -20 ℃ to+120 ℃.
4. ISWB type horizontal explosion-proof centrifugal 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 to+120 ℃.
STRUCTURE DIAGRAM The significance of ISW horizontal centrifugal pump model Special Instructions for ISW Horizontal Centrifugal Pump Single stage single suction centrifugal pumps below 7.5KW can be directly installed on the foundation with seismic isolation pads.
Single stage single suction centrifugal pumps above 7.5KW can be directly installed with casting foundations, or our unit's IS connection plate can be used in conjunction with seismic isolators for installation. The installation method of seismic isolators is the same as that of the seismic isolators used with ISG pumps, and the size of the seismic isolators used with pumps of the same specifications in the ISG series is the same. Installation instructions 1. Before installing a single-stage single suction centrifugal pump, the fasteners of the unit should be checked for looseness, and the flow channel of the pump body should be checked for foreign objects to prevent damage to the impeller and pump body during pump operation.
2. When installing a single-stage single suction centrifugal pump, the weight of the pipeline should not be added to the pump to avoid deformation.
3. When installing a single-stage single suction centrifugal pump, the foundation bolts must be tightened to avoid the impact of vibration on pump performance during start-up.
4. For the convenience of maintenance and safety of use, a single-stage single suction centrifugal pump is equipped with a regulating valve on the inlet and outlet pipelines of the pump and a pressure gauge near the pump outlet to ensure that it operates within the rated head and flow range, ensuring the normal operation of the pump and increasing its service life.
5. After the installation of a single-stage single suction centrifugal pump, the pump shaft should be moved, and the impeller should have no friction sound or jamming phenomenon. Otherwise, the pump should be disassembled to check the cause.
6. There are two types of single-stage single suction centrifugal pumps: rigid connection installation and flexible connection installation (see connection method).
working conditions 1. Single stage single suction centrifugal pump suction pressure ≤ 1.0MPa, or pump system high working pressure ≤ 1.6MPa, i.e. pump suction inlet pressure+pump head ≤
1.6MPa, pump static pressure test pressure is 2.5MPa, please specify the system working pressure when ordering. The working pressure of the pump system is greater than
When ordering at 1.6MPa, it should be separately stated. In order to use cast steel materials for the overcurrent and connection parts of the pump during manufacturing.
2. Single stage single suction centrifugal pump with ambient temperature<40 ℃ and relative humidity<95%.
3. The volume content of solid particles in the medium conveyed by a single-stage single suction centrifugal pump shall not exceed 0.1% of the unit volume, and the particle size shall be less than 0.2mm.
Note: If the medium used for the ISW horizontal centrifugal pump is with small particles, please specify it when ordering so that the manufacturer can use wear-resistant mechanical seals.
