Product details

overview

  • The DFG series (and derived hot water type) pipeline pump is designed by our company using hydraulic models and carefully designed according to different usage conditions for different types of users. The product quality follows the GB/T 5657-1995 "Technical Conditions for Centrifugal Pumps Class III" standard.

  • The DFG series pipeline pump simplifies the structure of intermediate transmission and enhances the smoothness of operation due to the direct connection between the motor and the pump. The pump adopts a pipeline structure, and the inlet and outlet of the pump can be installed at any position and direction of the pipeline like valves. Compared with ordinary horizontal pumps, it occupies 30% less space and has the characteristics of low operating noise and low vibration. The service life of vulnerable parts is greatly extended. This type of pump is widely favored in the market due to its stable performance, energy saving, small footprint, and compact structure.

purpose
  • Suitable for industrial, urban water supply, and high-rise building water supply;
  • Fire pipeline pressurization;
  • Cold and hot water circulation in air conditioning systems;
  • Long-distance water transportation;
  • The production process involves cyclic pressurization and conveying, and is suitable for supporting various water supply and drainage equipment, boilers, and other equipment;
