  • Page 7: Operating Principle

    Product Description | 2 2.1 Operating Principle 2.1.1 Once-Through Operation Gas discharge Process inlet Operating liquid inlet Continuous flow liquid system does not recover the operating liquid which flows out of the separator drain having been separated from the discharge gases which vent sepa- rately.

  • Page 8: Application

    2 | Product Description 2.2 Application Explosive gases and vapour mixtures can be drawn according to the scope of the Direc- tive ATEX 2014/34/EU. Depending on the equipment, the machine is intended for suction of explosive gases ac- cording to the data given on the nameplate of the machine (NP), see Explanation of AT- EX Classification [► 8].

  • Page 9: Vl System Description

    Product Description | 2 2.5 VL System Description In addition to the nameplate of the vacuum pump, a specific nameplate for the VL sys- tem is placed onto the base plate. The VL system description is written on the system’s nameplate. It is defined as in the following example: O = Once through liquid system P = Partial recirculation liquid system...

  • Page 10: Total Recovery (Closed Circuit)

    3 | Transport At the operating liquid inlet the Y-strainer (ST) prevents particles greater than 0.1 mm entering the vacuum pump. The manual fresh liquid isolation valve (IV) allows the system liquid inlet to be isolated whilst the strainer is cleaned. Operating liquid control valve (OPC) allows the operating liquid flow rate to be regulat- ed for optimum performance of the system.

  • Page 11: Storage

    Risk of damage to the machine! • 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. Installation 5.1 Installation Conditions WARNING The installation conditions are not respected in an ATEX environment.

  • Page 12: Connecting Lines / Pipes

    • Make sure that all provided covers, guards, hoods, etc. are mounted. 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.

    Installation | 5 CAUTION Restriction of the separator vent. Will cause back pressure and possible separator failure. • The separator vent piping should not be restricted as separator vessel is not pressure rated. • Make sure that the discharged gas will flow without obstruction. Do not shut off or throttle the discharge line or use it as a pressurised air source.
