product description
BLG(W) series single-stage single-suction vertical and horizontal centrifugal pumps are the high-efficiency and energy-saving products that our company adopts the BL type centrifugal pump performance parameters and the length of the vertical pump structure, and successfully designs in strict accordance with the national standard ISO2858 and national standards. New centrifugal pumps for conventional products such as IS-type horizontal pumps and DL-type pumps.
The flow range is 1.5~1200m/h, and the head range is 8~150m. There are more than 250 specifications including basic type, expanded type, A. B, C cutting type. According to the different fluid medium and temperature, we design and manufacture hot water pump, chemical pump, oil pump and explosion-proof chemical pump series products with the same performance parameters.

Working condition
1. The maximum working pressure of the pump system is ≤1.0MPa, please indicate the working pressure of the system when ordering. When the working pressure of the pump system is greater than 1.0 MPa, it should be proposed separately when ordering, so that during manufacturing, the over-current part and the connecting part of the pump are made of cast steel.
2. Applicable medium: The medium of the clean water pump should be free of corrosive liquids and solid insoluble materials, its volume should not exceed 0.1% of its unit volume, and its particle size should be less than 0.2mm.
3. The ambient temperature does not exceed 40C, the altitude does not exceed 1000m, and the relative humidity does not exceed 95%.

Application range
1. BLG(W) series vertical and horizontal centrifugal pumps are used to transport clean water and other liquids with similar physical properties to clean water. Use medium temperature below 80°C. It is suitable for industrial and urban water supply and drainage, pressurized water supply for high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance water delivery, heating, bathroom cold and warm water circulation pressurization and equipment support.
2. BLG(W)R series vertical and horizontal hot water pumps are suitable for heating systems for civil and enterprise buildings with heating systems and heating systems for production processes such as hot water pressurization, circulation, and transportation, such as power stations , Thermal power station, waste heat utilization, metallurgy, chemical industry, textile, wood processing, paper making and other industrial boilers high-temperature hot water, use temperature 95C:
3. BLG(W)H series vertical and horizontal chemical pumps transport liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. It is suitable for textile, petroleum, chemical, metallurgy, electric power, paper making, food, pharmaceutical and synthetic fiber sectors, and the operating temperature is-20C ~ 95C.
4. BLG(W)YGB series vertical and horizontal explosion-proof oil pumps are suitable for the transportation of non-corrosive, flammable and explosive liquids in the petroleum, light textile, chemical, machinery and other industries. The temperature of the transported medium is -20C-95C. Medium density p<1000kg/m'.
5. BLG(W)HB series vertical and horizontal explosion-proof chemical pumps transport liquids that do not contain solid particles, are corrosive, have a viscosity similar to water, and are flammable and explosive. Applicable to sectors such as textile, petroleum, chemical industry, metallurgy, mining, pharmaceutical and synthetic fiber; use temperature -20C-95C.
6. BLG(W)D series vertical and horizontal low-speed centrifugal pumps are suitable for chilled water, cooling water circulation and terminal boosting of air conditioning systems, local heating or terminal boosting circulation of urban heating systems, and local constant pressure of urban building fire protection systems And all kinds of air-conditioning hot water boiler supporting.

1. The pump has compact structure, small volume and beautiful appearance.
2. Easy installation. BLG series pumps have the same inlet and outlet diameters and are on the same center line, and can be installed directly in any part of the pipeline like a valve. Optional outdoor motor plus rain cover can be used outdoors. The pump is equipped with mounting feet so that the installation of the pump is stable.
3. Stable operation, low noise and high concentricity of components. The motor uses low-noise bearings and is equipped with a non-stop refueling device. The pump impeller has excellent dynamic and static balance, runs without vibration, and improves the use environment.
4. No leakage. The shaft seal adopts a corrosion-resistant and wear-resistant hard alloy mechanical seal, which solves the serious leakage problem of the centrifugal pump packing, extends the service life, and ensures the clean and tidy operation site.
5. Easy maintenance. There is no need to dismantle the pipeline, as long as the nut of the pump cover is removed, the motor and transmission components can be taken out for maintenance.
6. The pump can be installed vertically, horizontally, or in multiple ways according to the conditions of use on site. According to the flow head requirements, parallel and series methods are used to increase the required flow head.
