Pneumatic Calibration Pumps – Precise Vacuum & Pressure by Hand
Pneumatic calibration pumps generate vacuum and pressure without auxiliary power—ideal for field service, commissioning, and the lab. Depending on the model they cover −0.95 bar up to 20–60 bar and provide fine adjustment valves, fine volume control, and venting for stable, repeatable settings. Combined with reference gauges/sensors they form compact mobile calibration kits.
ICS Schneider Messtechnik supplies hand and bench pumps, matching references, adapters & hoses, seal kits, and DAkkS/ISO calibration—optionally as a complete service case.
FAQ on Pneumatic Calibration Pumps
Answers on selection, pressure ranges, stability, connections, tightness, media, and best practices.
What are pneumatic calibration pumps suitable for?
For generating and finely adjusting vacuum/overpressure when calibrating transmitters, pressure switches, and gauges—especially mobile and clean because there is no oil in the system.
What pressure ranges are typical?
| Range | Typical value | Use |
|---|---|---|
| Vacuum | down to approx. −0.95 bar | Pressure switches, leak tests |
| Overpressure | up to approx. 20–60 bar | Process/service calibration |
| Fine steps | mbar/Pa range | Low pressure, HVAC, lab |
How do they differ from hydraulic pumps?
Pneumatics are clean and fast but reach lower maximum pressures. Hydraulics offer very high pressures and maximum stability but require a medium (oil/water).
How do I achieve a stable reading?
- Use fine volume/micro adjust
- Keep it short: minimize hose length & dead volume
- Tight fittings, avoid temperature drift
Which connections are common?
| Thread | Standard | Note |
|---|---|---|
| G 1/4 / G 1/2 | ISO 228 | Industry standard, flat sealing possible |
| 1/4" NPT | ASME | Tapered, sealing compound required |
| Quick coupling | — | Fast DUT changeover |
Which references pair well?
Digital reference gauges or reference transmitters with suitable range/accuracy (e.g., ≤ 0.1% FS)—including DAkkS/ISO certificate for traceability.
How do I run a leak test?
Drive to the setpoint, isolate, then log pressure decay over a defined time. Consider ambient effects (temperature, volume).
Are there combo pumps for vacuum & overpressure?
Yes. Many hand pumps offer a switch between vacuum and overpressure—ideal for service and commissioning.
Which accessories are useful?
- Adapter sets (G/NPT, various sizes)
- Seal kits (NBR/FKM/PTFE) for tight connections
- Gauge/sensor holders, hoses, carrying case
How often should I calibrate the reference?
Typically annually (usage dependent). After shocks/overload, check immediately.
What safety aspects apply?
- Respect the maximum pressure of pump, hoses, and adapters
- Never disconnect under pressure; wear eye protection
- Use only clean, dry air/N₂
Tips for very low pressures (mbar/Pa)
Minimize dead volume, use ultra-fine valves, allow stabilization time, and shield the setup from drafts.
Do you supply complete calibration kits?
Yes—consisting of pump, reference, adapters/hoses, seals, and optional documentation templates (CSV/PDF).
