isw horizontal pipe centrifugal pump
product overview: the isw horizontal centrifugal pump is designed according to the unique structure combination of the is type centrifugal pump and vertical pump, and is designed and manufactured in strict accordance with the international standard iso2858 and the latest national pipeline centrifugal pump standard jb/t53058-93. . the pump adopts the domestic advanced hydraulic model optimization design. at the same time according to the use of temperature, different media, etc. derived on the basis of the isw-type heat pump, high temperature pump, chemical pump, oil pump, etc., is currently the national standard stereotyped promotion products.
features
smooth operation: the absolute concentricity of the pump shaft and the excellent dynamic and static balance of the impeller ensure smooth operation without vibration.
drips do not leak: different materials of cemented carbide seal, to ensure that there is no leakage of different media delivery.
low noise: two low-noise bearings supported the pump, running smoothly, in addition to the motor weak sound, basically no noise.
the failure rate is low: the structure is simple and reasonable, the key part adopts the international first-class quality; supporting, the whole machine trouble-free working time is greatly improved.
easy maintenance: replacement of seals and bearings is simple and convenient.
more land occupation: exports can be in three directions: left, right, and up, which facilitates piping installation and saves space.
product usage
1、isw horizontal water pump, used to transport clean water and other liquids with physical and chemical properties similar to clear water, suitable for industrial and urban water supply and drainage, pressurized water supply for high-rise buildings, garden sprinkler irrigation, fire booster, long-distance transport, hvac refrigeration cycle, bathroom and other hot and cold water cycle pressurization and equipment support, the use of temperature t ≤ 80 °c.
2, iswr horizontal hot water pump is widely used in: metallurgy, chemical, textile, paper, and hotels and restaurants such as boiler hot water pressurized cycle transmission and urban heating system, iswr type using temperature t ≤ 120 °c.
3, lswh horizontal chemical pump, for the transportation of solid particles without corrosive, liquid viscosity similar to water, suitable for petroleum, chemical, metallurgy, electric power, paper, food pharmacy and synthetic fiber and other departments, the use of temperature -20~c~ 120°c.
4, lswb horizontal pipeline pump, for the delivery of gasoline, kerosene, diesel and other oil products or flammable, explosive liquid, the temperature of the transport medium is a 20 ~ c ~ 120 °c.
