    ● The drained liquid should be separated twice and transferred to a safe place when applying the figure 1 arrangement. Particular care should be taken to avoid any leakage of dangerous gases from the water drain outlet. 6 | 40 Instruction Manual DOLPHIN LR 0110-0580 A_EN_en...
  • Page 7: Operating Principle

    The pumped medium is transported in the spaces between the blades and the liquid ring. The eccentric rotation of the impeller alters the volume of these spaces, causing gas to be drawn in, compressed and expelled. Instruction Manual DOLPHIN LR 0110-0580 A_EN_en 7 | 40...
  • Page 8: Intended Use

    ATEX supplement for additional safety information on operation in hazardous zones. Conveying of other media leads to an increased thermal and/or mechanical load on the machine and is permissible only after a consultation with Busch. The machine is intended for the placement in a non-potentially explosive environment.
  • Page 9: Transport

    ● Generally, the lifting point should be on the baseplate on which the machine is installed. ● The lifting point of a bare shaft pump is shown above. ● Check the machine for transport damage. Instruction Manual DOLPHIN LR 0110-0580 A_EN_en 9 | 40...
  • Page 10: Storage

    ● Drain the operating liquid from the machine and the system before storage. ● Or add an anti-freeze solution. After testing, all Busch DOLPHIN vacuum pumps are vented and drained. Short Term (Up to 3 Months) ● Seal all apertures with adhesive tape or provided caps.
  • Page 11: Installation

    ● Make sure that the coupling is correctly aligned, see Fitting the Coupling [➔ 17]. If the machine is installed at an altitude greater than 1000 meters above sea level: ● Contact your Busch representative, the motor should be derated or the ambient temperature limited.
