Page 9: Hazardous Substances
Basic Safety Instructions External mechanical stresses and vibrations must not be transmitted to the pump. Only use flexible vacuum hoses for connecting Rotary vane pumps. The pump should not be used to suck up fluids. Lay the exhaust pipe so that it slopes downwards, so allowing condensate to flow out of the pump. -
Page 10: Description
Description Description 3.1 Design The CRVpro series vacuum pumps are oil-sealed, two-stage Rotary vane pumps. The drive motor is directly flange-mounted onto the motor cover of the pump holder and the pump shaft and the motor shaft are connected to each other by an elastic coupling. The bearings of the interior pump body are force-fed lubricated sliding bearings. - Page 11 Description Followed the scope of delivery for standard model numbers. The scope of delivery for other model numbers is specified in the supply contract. P1700040...

Page 12: Function
Description 3.4 Function 3.4.1 Principles of Vacuum Pump Operation The main purpose of a vacuum pump is to reduce the pressure in a vessel or a closed system. The degree of pressure reduction is dependent upon the requirements of the application and the type of vacuum pump employed. - Page 13 Description Two pump stages (fore-stage and high-stage) are arranged in series in order to improve the end pressure and the pumping speed at lower pressures. The intake takes place in the first stage (high- stage), the compression and the outlet in the second stage (fore-stage). Fig.

Page 14: Oil Functions
Description This state of equilibrium is referred to as the ultimate pressure or blank off pressure of the pump and its system. No matter how much additional pumping time is provided, no further reduction in system pressure will be accomplished once ultimate pressure is attained. Intake Anti-suck back Protection When power to the pump is turned off, this device closes automatically, maintaining vacuum in the system being evacuated, and vents the inside of the pump to atmospheric pressure. - Page 15 Description When pumping condensable vapours, they may be compressed during the compression phase above the saturated vapour pressure and condense. This causes considerable deterioration in the vacuum pump’s performance: ultimate pressure is not achieved corrosion occurs heavy oil contamination and formation of emulsions CAUTION! Operating with gas ballast increases the operating temperature of the vacuum pump by 5 –...

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

Page 27: Side Panel Fitting Port
Installation and Operation can produce dangerously high pressures. If the trap becomes saturated it should be disconnected from the system, drained and cleaned. An increase in pressure in the vacuum system will normally indicate that the trap has become saturated. To clean the trap, remove the trap from the system, allow the trap to warm up and rinse off the condensate with a suitable solvent in a fume hood. -
