XD-040 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 40 m3 / h, ultimate vacuum for 2X102Pa, motor power 1.1KW, air intake diameter G1 1/4 pump speed is 1420 rpm, weight 58kg. 
    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 into the "filter into the pump chamber when the rotor rotates, the completion of self-isolation chamber and suction gas through the inlet and compressed by the pump chamber and the discharge check valve and through the opening path between the gas tank the gas discharge. revolution, the operation was repeated three times. All pumps by direct drive motor through flexible coupling 
   XD-040-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; vacuum fixture machining on; transport operations in the vacuum handling; hospital operating room vacuum suction; blister on the plastic molding industry.
