BELT DRIVE
• Install a suitable pulley on the smooth
shaft as close as possible to the pump: max 35 mm.
• Apply an adequate belt tension (see manufacturer’s data). Max 3000N.
• Do not use driven or driving pulleys with a pitch diameter inferior to 180 mm. Small pulleys
require a high belt tension which may cause premature wear to the bearing or transmission
troubleshooting
NOTE
If the pump PN155 is run through a belt drive, its working pressure must not exceed 1.5 abs.
bars to prevent it from absorbing a power requiring an excessive belt tension. There is no limit
to the operation in vacuum.
