Page 7: Description And Characteristics
Technical description The VACSOUND ECO D12, D18 and D28 pumps are twin-stage, rotary, vane pumps with an oil-bath seal, driven by a single-phase or three-phase electric motor. These high vacuum pumps are suitable for pumping of neutral gases and CFC, HCFC and HFC steams. -
Page 8: Lubrication
Lubrication The pump’s lubricating system is force-feed type. Oil circulation is obtained by means of a gear pump connected to the rotor shaft. The oil is sucked through a gauze filter to prevent any foreign bodies from entering the pump. Shunt-mounted on the delivery line is a hydraulic piston which, besides actuating the anti- suckback device (see section 2.6), also regulates pressure by discharging excess oil flow directly into the tank. -

Room temperature should ideally be between 12 °C and 45 °C. If the temperature is not inside this range, consult GALILEO TP technical service for the changes required. Setting the pump in position should be performed as follows: •... -
Page 14: Preliminary Operations
Preliminary operations Before starting the pump, fill up with lubricating oil as the pumps are delivered empty. NOTE: A tin of oil is included in the packing. For details on how to fill up, see Scheduled Maintenance Card 01 (Section 4.5). CAUTION: Oil must be poured into the casing through the special threaded plughole and NOT through the suction line. -
Page 15: Connections On Suction And Exhaust Sides
Connections on suction and exhaust sides Remove the protective caps from both flanges. Connect the system to be evacuated to the suction flange, using a centering ring with OR and a locking collar. NOTE: For guaranteed reliable sealing, use an OR gasket in Perbunan or Viton. The suction duct is equipped with a sieve filter preventing solid particles from entering and damaging the pump. -
Page 16: Stopping The Pump
The gas ballast valve will prove useful in the cold season when, due to the lower room temperatures, it takes longer for the pump to reach rated temperature when switched on. Compression of the air forced in by the gas ballast valve develops heat, which in turn increases temperature of the oil faster. -
Page 17: Maintenance
4. Maintenance Purpose of this chapter Chapter 4, MAINTENANCE, provides a rundown of the main maintenance operations, and contains a lubrication table; also included are the Scheduled Maintenance and Unscheduled Maintenance cards. Safety rules Personnel responsible for pump operation and maintenance must be well-trained and must be aware of the accident prevention rules. -
Page 18: Caution Notes
Do not wear any objects that may become entangled in the mechanisms and/or act as conductors (chains, bracelets, etc.). k. Ensure that the tools to be used are in perfect working condition and have insulating grips, where necessary. Check that the insulating material of the cables and that the conductors of the test equipment do not show any signs of damage. -
