BL monoblock centrifugal water pump is a single-stage single-suction cantilever direct-connected clean water centrifugal pump and improved on the basis of BA type pump. BL centrifugal pump has the advantages of small appearance, light weight, simple structure and easy installation. BL centrifugal pump can be used for conveying clean water and liquids with physical and chemical properties similar to water. It can be used with ZS vacuum jet pump.
The main parts of BL centrifugal pump are for pump body (1);The impeller (2);Connecting shaft (3);Rear cover. The pump outlet is perpendicular to the pump shaft and can be rotated with the pump body at 90, l80, and 270 angles according to installation conditions. The pump is equipped with mechanical seal.
BL centrifugal water pump is Suitable for industrial and urban water supply and drainage, pressurized water supply in high-rise buildings, sprinkler irrigation in gardens, pressurized fire control, long-distance transmission, hvac refrigeration cycle, bathroom and other cold and warm water cycle pressurized equipment. Liquid temperature T≤80℃.
BL centrifugal hot water pump is Widely used in metallurgy, chemical industry, textile, paper and hotels and other boiler hot water pressurized circulation transmission and urban heating system, the liquids temperature T≤120℃.
