2-STAGE ROTARY VANE VACUUM PUMP
30│40│60│90
AVR - 10 (16) is a two-stage straight rotary vane vacuum pump (hereinafter referred to as the pump).The pump is mainly composed of drive motor and pump body of two parts.Directly coupling drive motor and pump body, pump and motor shaft by the elastic coupling, the fan is mounted on the shaft coupling, by cooling around the coupling aperture and pump body even in extreme conditions can maintain at a low temperature, combining with the fin on the pump body, make full use of air cooling and oil cooling to get heat dissipation.For oil pump internal all bearing lubrication of the sliding bearing.Pump body composed of o-rings seal assembly, all parts are used in order to remove the locating pin connection, the pump body is easy to remove the and do not need special tools, convenient repair and maintenance.
