DL type series vertical multi-stages pumps are used to pump clean water as well as the liquids similar to clean water in physical and chemical properties whosetemperature is less than 80º C. The temperature of liquid pumped by DLR type hot water pumps is less than 140º C. Compared with the vertical multi-stages pumps and due to the small torque of rotor of multistage pump, DL type and DLR type pumps not only have reliable operation, small vibration, low noise and long service life, but also have the characteristics of compacting structure, less occupying land and convenient to mounting. According to the service requirement, the relative angle of inlet and discharge of pump can be adjusted at four directions (0° , 90° , 180° And 270° ), so it is convenient to make layout of pump and pipeline.
Application
The pumps are used for water supply for high building, fire-fighting, heating, air condition system and public water supply for residential quarter in town orcity and can be applied for water supply and drainage in factories and mines as well as circulating water for low pressure boiler.
