Page 7: Operating Principle
Product Description | 2 NOTICE If applying the configuration shown in figure 4. The discharge pressure will rise and lead to an increase in shaft power. • Make sure the cross-sectional area of the gutter is large enough. NOTICE If recirculation of the service liquid is not required. Drainage of the liquid should comply with the appropriate environmental regulations. -
Page 8: Application
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. The machine is capable of maintaining ultimate pressure, see Technical Data [► 26]. -
Page 9: 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. 4.1 Short Term (Up to 3 Months) • Seal all apertures with adhesive tape or provided caps. -
Page 10: Installation
• Make sure that the coupling is correctly aligned, see Fitting the Coupling [► 15]. 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. -
