The pump with a 540 rpm gear box can be transformed into a pump with a 1000 rpm gear box (and vice versa).
• Remove the gearbox as above described. Remove also the pinion from the drive shaft.
• Install the new pinion and tight the nut as prescribed.
• Mount the new gear wheel including bearings and seals on their housings in the front cover, properly
aligned. This assembly can now be installed in the gear box: fit the front bearing in the specific seat of
the flange/cover.
• Properly engage gears, replace the cover’s gaskets to complete correctly the job. Insert the aligning
pins, which maintains the correct positioning.
The vacuum pump overheats
Insufficent or absent lubrication Verify oil and rings. Check oil pump efficiency
Low oil level Fill the oil tank
Too high rotation speed Reduce rpm to the prescribed one
Prolonged functioning at the max vacuum rate Reduce vacuum rate
Vacuum and/or exhaust line of insufficient diameter
Check dimensionino
The vacuum pump does not rotate
Broken vanes: Clean inside chambers, replace vanes
- due to infiltraded solids
Check the secondary shutoff and filters of the
suction line
- due to insufficient lubrication Check the oil pump
Power transmission breakdown Check and replace the damaged parts
Ice inside the pump (during the cold season) Remove ice and slowly start. Avoid suction of water
Performances loss
Four way changeover valve in idle position Move the lever in vacuum or in pressure mode
