Series R is mainly used for conveying high-temperature and high-viscosity polymer melts, such as in resin, chemical fiber and other industries. It is generally installed at the bottom of the reactor and used as a discharge pump. It can also convey medium and high viscosity media in vacuum reactors. With a large flange design at the suction port, it can smoothly suck high-viscosity media under vacuum conditions, and complete the conveying and pressurization of polymer materials under vacuum reaction conditions. It can also be used to convey high-viscosity materials without particulate impurities such as hot melt adhesive, asphalt, adhesive, pharmaceutical raw materials, food, grease, fuel, oil, dyes, coatings, lubricants, etc.
1) Applicable to working conditions of high temperature (350℃), medium and high pressure (15MPa) and high viscosity (20,000Pa·s);
2) Small pressure and flow pulsation, realizing nearly linear flow output and easy control;
3) Excellent self-priming performance, applicable to working conditions with vacuum at the inlet (-0.05～-0.09MPa);
4) Precise structure, high precision and long service life.
