VTLF 2.250 Becker Vacuum Pump

 Installation and Service Guide

   Installation for CanCam C2-510 ATC CNC router machine

Tools Required:

Teflon tape

Phillips screwdriver

Flathead screwdriver

Components Required:

(2) Becker exhaust muffler

(3) 2-1/2 inch threaded pipes

(2) 4-inch hose clamps

(1) 90deg 2-1/2 inch pipe (OPTIONAL)

(1) 2-1/2 inch vacuum hose

(1) Becker dust filter

(1) Vacuum inlet fitting (provided with C2-510ATC CNC machine)

1. Mount the machine in a well‑ventilated environment
   
   

• Place on a flat, rigid surface with clear airflow around the fan and shrouds
  
  

• Install and level vibration feet so the unit does not rock
  
  

2. Install the mufflers on the exhaust towers
   
   

• Apply PTFE tape to the exhaust threads
  
  

• Thread mufflers on by hand, then snug with a wrench while supporting the tower
  
  

• Orient vertically so condensate can drain and nothing contacts guards

3. Install the three pipes and 90° bend for the Becker dust filter on the top of the pump
   
   

• Dry‑fit the three pipes and the 90° bend to confirm alignment and filter location
  
  

• Apply thread sealant to each joint and assemble hand‑tight, then wrench‑snug
  
  

• Mount the dust filter so the bowl is horizontal and accessible. 

4. Install the 2.5-inch vacuum hose from the dust filter to the C2-510 ATC CNC router 
   
   

• Assemble the vacuum inlet that is provided with the C2-510 ATC CNC router as such

• Route the hose from the filter outlet to the router vacuum manifold without kinks

• Slide a clamp on each end, push the hose fully onto the fittings, and tighten the clamps

• Add supports so the filter is not carrying pipe weight

Vacuum pump service guide

(Service should be completed every 3000 hours of use)

Tools and materials

• 5 mm hex key or bit
  
  

• 13 mm socket and torque wrench
  
  

• Clean rags
  
  

• Air compressor
  
  

• Callipers or micrometer
  
  

• PPE (gloves, safety glasses)
  
  

• Grease injector insert (provided with pump)

1. Remove the rear panel
   
   

• Disconnect and lock out power
  
  

• Remove four 5 mm hex bolts from the back plate
  
  

• Set the panel aside

• Disconnect the pink grease line

2. Remove the vacuum housing face plate
   
   

• Use 13M socket to remove the bolts securing the face plate
  
  

• Keep bolts for reinstallation

3. Separate the face plate from the housing
   
   

• Thread two 5 mm hex bolts into the push bolt holes on the face plate
  
  

• Evenly tighten to push the plate away from the housing

4. Remove compressor fins
   
   

• Carefully slide out the five fins from the rotor slots
  
  

• Keep track of their orientation

5. Measure fins
   
   

• Use callipers to measure the width of each fin
  
  

• Minimum width is 41 mm
  
  

• Replace any fins at or below the minimum or showing damage
  
  

6. Clean housing interior
   
   

• Wipe the inside of the housing with a clean rag
  
  

• Use compressed air to blow out dust and debris
  
  

• Ensure surfaces are smooth and free of residue

7. Reinstall fins
   
   

• Insert fins in the same orientation they were removed
  
  

• Ensure they move freely in the slots

(Correct - edge flush with surface)            

 (Incorrect - not flush with surface)     

      

8. Reinstall face plate
   
   

• Position plate on housing and align bolt holes
  
  

• Install 13 mm bolts and torque evenly in a star pattern to 50 Nm
  
  

9. Reinstall rear panel
   
   

• Secure with four 5 mm hex bolts
  
  

• Check all fasteners for tightness
  
  

10. Service intake filter and grease fittings
    
    

• Remove clear filter cover by loosening four plastic hand screws
  
  

• Take out the filter and check for damage
  
  

• If needed, spray with compressed air to clean
  
  

• Insert grease injector into each grease nut inside filter housing area
  
  

• Pump 25 strokes into each of the two grease fittings
  
  

• Reinstall filter and clear cover; tighten plastic hand screws
