REPLACING BECKER KDT 3.80 CARBON VANES

The Becker KDT 3.80 uses 4 WN 124-034 carbon vanes. Many maintenance engineers and factory service departments replace these vanes in-house as part of routine pump servicing.
When replacing the vanes, check the condition of the pump rather than simply fitting a new set. Areas worth inspecting include:
✓ Rotor and rotor shaft condition
✓ Cylinder body condition
✓ Bearings
✓ Inlet filter
✓ Relief valve operation
✓ Signs of overheating or contamination inside the pump
Uneven, chipped or unusually rapid vane wear can indicate another problem within the KDT 3.80. Identifying the cause before installing new vanes can help prevent repeat wear or pump damage.

BECKER KDT 3.80 VANE FITTING & PUMP SERVICING

Customers with experienced maintenance engineers will often replace KDT 3.80 vanes themselves. For customers who prefer engineering support, VacAir can carry out the vane replacement and assess the general condition of the pump.

Our experienced, OEM factory-trained vacuum pump engineers can attend site to replace the vanes, or your Becker KDT 3.80 can be returned to our workshop for inspection, servicing, repair or full overhaul.

Workshop inspection can be particularly useful where the reason for poor performance is uncertain, allowing the internal pump condition to be checked rather than assuming that worn vanes are the only cause.
