XD-020 is a single-stage rotary vane vacuum pumps mechanical vacuum pump, simple structure, easy to operate, easy to maintain, is a vacuum using a wide range of access to basic equipment. It pumping rate of 20 m3 / h, ultimate vacuum for 2X102Pa, motor power 0.75KW, air intake diameter G1 1/2 im, pump speed 2800 rpm, weight 20kg. 
It works the same as the general volume of the pump, by a concentrically mounted drive shaft and the pump body is composed of an eccentric position of the rotor, there are three radially sliding vanes, the pump chamber is divided into three working chambers of the rotor is pumping gas from the suction port to enter through the opening of the check valve and the filter and into the pump chamber when the rotor rotates, the completion of self-isolation chamber and the suction gas is compressed and the air intake port through the pump chamber and the exhaust box the path between the gas discharge. Rotation, the operation was repeated three times. All pumps by Direct drive motor through flexible coupling. 
XD-020-type rotary vane vacuum pumps suitable for various industrial applications, such as: various types of food vacuum packaging on the food industry; vacuum various soft goods on the textile industry compression packing; vacuum drying on the chemical industry, distillation, concentration; machining on a vacuum chuck; transport operations in the vacuum handling; hospital operating room vacuum suction; blister on the plastic molding industry.
