  • Page 5: Operating Principle

    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 unless a "Ex(outside)" sign is written on the nameplate, in this case please refer to the ATEX supplement for additional safety information.

  • Page 6: Variants

    Dolphin LTs are two-stage vacuum pumps and operate from atmospheric pressure to 33 hPa (mbar) ultimate pressure. 2.4.3 VL System VL System consists of a Dolphin machine either LM or LT and an operating liquid supply system. Three different layouts are possible: –...

  • Page 7: Transport

    • 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. Pumps contain- ing ferrous materials are preserved using a combined VPI (Vapour Phase Inhibitor) and Contact Inhibitor Oil (Vaporol™...

    5 | Installation 4.2 Medium Term (3 Months to 6 Months) • Remove the shaft coupling guard (if not supplied as a bare shaft machine). • Rotate the machine shaft by hand weekly to prevent bearing indentation. • Leave the shaft at approximately 90 degrees to the original position, using a tempor- ary mark on the shaft to assist.

  • Page 9: Connecting Lines / Pipes

    • Make sure that the coupling is correctly aligned, see Fitting the Coupling [► 13]. 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.

  • Page 10: Operating Liquid Connection

    If the machine is equipped with a VL System (see reference on the nameplate): • Consult the supplement to the instruction manual of the VL System for additional information. Dolphin LM 0100-0800 A OPI1 OPI2** Dolphin LT 0130-0750 A...

    Commissioning | 6 NOTICE Incorrect direction of rotation. Risk of damage to the vacuum system! • Operating the vacuum system with the rotation in the wrong direction can result in the operating liquid flowing back to the vacuum system. Prior to start-up, check for correct direction of rotation.

  • Page 16: Preventing Cavitation

    7 | Maintenance 6.1 Preventing Cavitation NOTICE Cavitation. Risk of damage to the machine! If you hear crackling noise: • Control the pressure. At very low pressures and sufficiently high temperatures the operating liquid can locally transfer into the vapour phase, creating bubbles within the operating liquid. As the pres- sure rises towards the outlet slot the bubbles collapse.

  • Page 17: Maintenance Schedule

    If an inlet screen is installed: • Check it and clean if necessary. Every 5 years • Have a major overhaul (contact Busch). * For Dolphin LM 0800 A, LT 0630-0750 A only. Smaller Dolphin LM/LT use bearings which are greased for life. Overhaul NOTICE Improper assembly.
