Product overview：
DFG series (and derived from hot water type) pipeline pumps are carefully designed by our company based on the hydraulic model of ^ and according to the famous users under different service conditions. The product quality is in accordance with the standard of GB/T 5657-1995 Technical Conditions for Centrifugal Pumps, Class III.
Due to the direct connection between the motor and the pump, the DFG series pipeline pump simplifies the structure of the intermediate drive and enhances the stability of operation. The pump adopts a pipe-type structure. The inlet and outlet of the pump can be installed at any position and in any direction of the pipeline like a valve. Compared with the ordinary horizontal pump, the floor area is reduced by 30%, and has the characteristics of low operating noise and low vibration. The service life of wearing parts is greatly extended. This type of pump is widely favored by the market due to its stable performance, high efficiency and energy saving, small floor area and compact structure.
