Page 12: Working Principle Of Two-Stage Rotary Vane Pumps (Crvpro Series)
Description Fig. 2 Rotary vane pump Principle The rotary action of the pump creates a hollow space of chamber (1) which expands as the pump rotates. As the chamber expands, the pressure in the chamber decreases. As a result, gas is drawn into the chamber due to the difference in pressure between the chamber and the inlet (4) to the chamber (The inlet is the only place where gas can flow into the chamber). - Page 13 Description When in operation, the intake stage is at lower pressure and the exhaust stage is at higher pressure relative to each other. Each stage contains a rotor assembly consisting of a rotor with two vanes and a stator. The two rotors are combined on one shaft, and the two stators are combined in a common housing.

Page 14: Oil Functions
Description 3.4.4 Oil Functions WARNING ! Vacuum pump is shipped without oil inside to prevent possible spillage during shipment. Oil must be added prior to use! The oil fulfils the following functions in the vacuum pump: · lubricating the sliding parts, such as rotor, vane, radial shaft seals ·... - Page 15 Description CAUTION ! Operating with gas ballast increases the operating temperature of the vacuum pump by 5 – 10 K. The gas ballast valve can increase the pump’s water vapour tolerance. In many vacuum pump applications the gases being pumped from a system are a combination of permanent gases and undesirable vapours such as water vapour.

Page 18: Lubrication Data
Technical Data 4.5 Lubrication Data Welch Directorr™ Premium vacuum oil is a triple-distilled hydrocarbon oil using severely hydrotreated base stock. The oil is designed to resist breakdown at higher RPMs and operating temperatures of direct-drive vacuum pumps. The hydrotreating virtually eliminates aromatics and sulfur to give good resistance to sludge and varnish formation over time in corrosive environments. -
