SNF flange type is designed and manufactured according to the national standard GB10887-89. SNF flange type is a rotor-type positive displacement pump, which utilizes the screw meshing principle and relies on the rotating screw meshing each other in the pump sleeve to seal the medium to be transported in the meshing cavity and push it to the discharge outlet continuously and uniformly along the axial direction of the screw to provide stable pressure for the system. SNF flange is suitable for conveying various non-corrosive oils and similar oils and lubricating liquids. The viscosity of the conveying liquid is generally 3.0 ~ 760mm2/S(1.2 ~ 100°E), and the high viscosity medium can be transported by heating and viscosity reduction. Its temperature generally does not exceed 350℃.
★ Stator and rotor contact spiral sealing line will separate the income chamber and discharge chamber, so that the pump has the function of valve partition;
★ Can realize liquid, gas, solid multiphase mixed transport;
★ Pump fluid flow volume does not change, no ripple agitation and pulse;
★ The volumetric cavity formed by the elastic stator can effectively reduce the wear of conveying medium containing solid particles;
★ The viscosity of the input medium can reach 50000Mpa·s and the solid content can reach 50%;
★Flow and speed proportional, with the help of the governor can realize the amount of automatic adjustment ;
