- Page 10 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 12 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 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 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.

- Page 21 Installation and Operation 5.5.1 Connecting to the Electricity Supply The standard pump is supplied with complete electrical wiring. It is connected via an appliance cable and a power supply plug. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
- Page 22 Installation and Operation 5.5.2 Installation of the Grounding Plug For UL ONLY RELEVANT FOR UL (115V, 230V / 60HZ) OPERATION This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug.
- Page 23 Installation and Operation 5.5.3 Motor Protection All A.C. motors are provided with a thermal overload protection ex works, protecting the motor and vacuum pump from damage or destruction, respectively. The motor manufacturer makes motor thermal overload protection available as an aid to minimize motor failure. Overload protection is a standard feature on the single-phase motor.
- Page 24 Installation and Operation 5.7 Operating Temperature The function of the vacuum pump filled with Directorr™ Premium vacuum oil is guaranteed between ambient temperatures of 10°C and 40°C. The lowest starting temperature is 12°C. The pump must be vented on the suction-side (suction port open). WARNING ! In dependence on the operation mode, the casing temperature can reach 90°C.
- Page 25 Installation and Operation 5.10 Trap installation and maintenance Where corrosive vapors or large quantities of condensable vapors are evolved from vacuum processing, a cold trap may be used in the connecting line to the pump. It will help prevent damage to the pump mechanism and reduce oil contamination. The cold trap, immersed in a suitable Dewier flask, is installed so that the vapors may come in contact with the surfaces of the trap and condense.
- Page 26 Installation and Operation 5.13 Scrap Disposal CAUTION ! The rotary vane pumps must be disposed of in accordance with the 2012/19/EU directive and the specific national regulations. Contaminated rotary vane pumps must be decontaminated according to the laws. P1700017...
