TechWest GoldenVac Stainless Steel Vacuum Pump
TechWest · Model GoldenVac Stainless Steel Vacuum Pump
Dental vacuum pump The stainless steel castings provide maximum durability to prevent wear from air abrasion and ceramic particles, or hard water conditions. All motors are thermally protected and are cap-start, cap-run. This will lower the electrical consumption of the pump. Water recyclers and air-water separators are available for all pumps. The GoldenVacs are available in single, dual, or triple configurations. Tech West will provide plumbing and electrical designs upon request.
Key tips
- ·Biological-indicator verification applies to dental sterilizers exactly the same as hospital CSSD - no exception for smaller units.
- ·"Sounds different" is often the first real report of handpiece bearing wear, not an outright failure - investigate early rather than waiting.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Compressor pump fault
MediumSymptoms: Low air pressure, excess noise.
Root cause: Worn piston/diaphragm or pump motor wear.
Air dryer / filter clogging
MediumSymptoms: Moisture in line, reduced output pressure.
Root cause: Saturated desiccant or clogged filter element.
Check valve wear
LowSymptoms: Pressure bleed-down when idle.
Root cause: Worn or stuck check valve.
Pressure switch fault
LowSymptoms: Won't cycle on/off correctly.
Root cause: Switch contact wear.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily handpiece lubrication and autoclave cycle verification
- ·Compressor moisture-trap draining
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Compressor pump fault
- Confirm the presentation - typically low air pressure, excess noise - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: worn piston/diaphragm or pump motor wear.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the compressor pump head per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
