    Operating and maintenance instructions 1. General information This manual contains information necessary for the proper operation of the pump in order to prevent unsuitable use and for the safety of the operators. Do not attempt any other type of operation without having first contacted our Service Department. The information provided herewith does not intend to replace, integrate or change any rules, regulations, law by decree, directive or law of specific character in force in the Country where the installation takes place.

  • Page 4: Product Specifications

    Operating and maintenance instructions 2. Product specifications 2.1 Pump description EU 205 - EU 300 pumps are single-stage, rotary vane lubricated vacuum pumps, with oil recirculation. The flanged electric motor is coupled by means of an elastic coupling. Cooling is achieved by means of an air/oil cooler and a centrifugal fan.

  • Page 5: Expected Use

    40°C. In case you get temperatures outside this range, please get in touch with us. Handling of other types of gas or vapours must be declared in advance to PVR that will give the conformity to the specific use.

  • Page 6: Safety Rules

    Operating and maintenance instructions 3. Safety rules WARNING: Despite of all the precautions adopted when designing the equipment, there are some risk elements that arise during operation and servicing. HOT SURFACES The temperature of the pump surfaces may exceed 80°C. Install the pump in a protected area accessible only by authorized personnel, to prevent possible personal injures due to contact with hot surfaces.

  • Page 7: Electric Safety

    Operating and maintenance instructions ELECTRIC SAFETY Some components of the electric equipment are electrically charged during operation. Any contact may cause serious injuries to persons or objects. Connection and control of the electric system must be carried out by skilled personnel only.

  • Page 8: Transport/Handling

    In case of damages are found, inform immediately PVR and the carrier. A representative will contact you or it may be dispatched to the site to inspect and file full damage report.

    Operating and maintenance instructions 5.2 Operating vacuum range changing Pumps of EU205 - EU300 series are fitted with a manual selector switch for the choi- ce of the suitable working vacuum range: · EU from 0.5 to 300 mbar · EU/B from 10 to 850 mbar In case the pump working range needs to be changed, please follow the instructions (fig.3).

  • Page 11: Location

    Operating and maintenance instructions 5.3 Location WARNING: The pump must be installed in a protected area (see safety rules). It must be fastened with support feet on horizontal surface. It must be accessible for correct and easy maintenance, by respecting the minimum distances from possible obstructions (see figure 6).

  • Page 12: Connection To The Machine

    Operating and maintenance instructions 5.4 Connection to the machine The connection to the chamber to be pumped down must be carried out by means of pipes of the same diameter as the inlet port. Pipe weights and expansions, if any, must not rest on the pump. It is advisable to make the final connection to the pump inlet port with flexible pipes or fittings.

  • Page 13: Electrical Connection

    Operating and maintenance instructions 5.6 Electrical connection The control panel and electrical connections must be carried out by skilled personnel and conform to the EN 60204-1 rules or to other local regulations in the Country of use. The electrical equipment must comply with EN 61000-6-4 and EN 61000-6-2 standards concerning electromagnetic compatibility, emission standard and immunity for industrial environment.

  • Page 14: Commissioning

    Operating and maintenance instructions 5.7 Commissioning The pump is supplied without lubricating oil. NOTE: the operation without oil causes big damages to the pump. Carry out the first filling up through the plug (E) up to the half of the sight glass (F) and close the plug (E) (Figure 8).

  • Page 15: Water Vapour Intake

    Operating and maintenance instructions 5.9 Water vapour intake In order to pump down any water vapour, the following operations are recommended: Let the pump run for thirty minutes at the maximum vacuum in order to bring the pump temperature to its operating value. At the end of the working cycle, in case of further presence of condensate in the oil, let the pump run for at least thirty minutes at the maximum vacuum.

  • Page 16: General Information

    Operating and maintenance instructions 6.1 General information In order to keep the pump operating at a high efficiency level, it is mandatory to follow all periodical service points listed in the table below.However, more frequent service operations may be necessary depending on what the pump is used for (suction of con- densable vapours, suction of powders or polluting substances).

  • Page 17: Coupling Elastic Element Replacement

    Operating and maintenance instructions 6.2 Oil change For a correct operation, oil change should be performed when the pump is still warm. WARNING: Use protective gloves to avoid injury caused by heat. Please refer to Figure 8, section 5.6.Unscrew the oil filling plug (E) and the discharge plug (G) only after having placed underneath the pump tank a suitable container (proper size and shape) for collecting the total quantity of oil.

  • Page 18: Exhaust Filters Replacement

    Operating and maintenance instructions 6.4 Exhaust filters replacement Very dirty exhaust filters may cause a considerable pump temperature increase and in extreme cases oil lubricant spontaneous ignition. Maximum allowed pressure in the tank is 0,6 bar measured at the maximum capacity (when the pump is working with the inlet open to atmospheric pressure).

  • Page 19: Lubricants

    9. Return for repair In case of pump return for repair to PVR, provide a list of substances which have come in contact with the pump and advise the risks involved in handling, if any. Drain the lubricant from the pump prior to shipping the pump back.
