ISGD low speed centrifugal pumps
introductions
ISGD type low speed centrifugal pump is based on ISG type centrifugal pump and refer IS type centrifugal pump performance parameters, according to the centrifugal pump special structural combined design and manufacture. This product adopts the domestic water pump experts provided the most advanced hydraulic model, energy efficient, reliable performance, deeply praised by domestic and foreign merchants.
features
ISGD type low speed centrifugal pump is based on ISG type vertical centrifugal pump to match low speed motors, greatly reduces the operating noise, prolongs wearing parts service life, is most suitable for air circulation and heating circulating and knids of circulation system end pressurization. The innovative design of vertical structure makes its covering less space, and more convenient in using.
main usages
ISGD type low speed centrifugal pump: mainly used in air conditioning system cooling water, cooling water circulation and end pressurization, and city heating systems, local or end pressurization, urban construction fire fighting system local constant pressure and kinds air conditioning hot-water boiler mating.
working conditions
ISGD type motor above 0.75 kw, pump system maximum pressure is 1.6 Mpa, ie pump inlet pressure + pump head ≤1.6Mpa, pump static pressure test pressure is 2.5 Mpa, below 0.75kw, pump system maximum working pressure is 0.8 MPa.
