Automatic vacuum pumping unit HKDR500-90

The roots rotary unit is a combination of a roots pump as the main pump and a rotary vane vacuum pump as the backing pump, equipped with filters, a control box and corresponding pipes and valves, becoming a new type of vacuum pumping equipment. This unit will make up for the insufficiency of original vacuum pump. Technical Data Roots rotary unit： The roots rotary unit is a combination of a roots pump as the main pump and a rotary vane vacuum pump as the backing pump, equipped with filters, a control box and corresponding pipes and valves, becoming a new type of vacuum pumping equipment. This unit will make up for the insufficiency of original vacuum pump. Roots rotary unit advantages: Increase pumping capacity - a Roots vacuum pump can increase the total (instantaneous) pumping capacity. Increase the service life - roots vacuum pump can reduce the temperature rise of the vacuum pump,making the pump no overheat; can reduce the running time of the vacuum pump; if adding a buffer tank and air filter,it can reduce foreign matter and micro-granular solids into the vacuum pump. Eliminating returning oil problem of the pump - the unit is designed with a oil-repellent structure. When the entire pumping device is stopped, the vacuum pump oil will not return to the sucked container. Roots screw unit application range: The vacuum unit is suitable for environmental protection and clean application processes in the pharmaceutical, chemical, electronics and other industries. Roots rotary unit application range: The vacuum unit is suitable for using as a main pump or backing pump in vacuum systems, which requires high pumping speed at low inlet pressure.
