Pneumatic Calibration Pumps – clean pressure/vacuum generation up to ~40 bar
Pneumatic calibration pumps generate vacuum and overpressure using air or nitrogen—ideal for calibrating gauges, pressure transmitters, pressure switches and loggers in the low/mid-pressure range. Coarse generation (lever/screw) plus a micro volume adjuster provide stable, mbar-fine setpoints without overshoot—in the lab or in the field.
Key features (model-dependent): typical ranges 0…−0.95 bar (vacuum) and 0…+20/40 bar (overpressure), media air/N₂ (oil- and particle-free), integrated bleed/bypass valves, fine adjuster, reference/DUT ports with quick couplers, rugged carry cases, threads G 1/4 (BSPP), NPT, M20×1.5 and 7/16″-20 UNF for microbore hoses.
ICS Schneider Messtechnik supplies pumps, reference gauges/sensors, adapter/hose kits and—on request—factory/DAkkS calibration as a ready-to-use kit.
FAQ on Pneumatic Calibration Pumps
Answers on ranges, stability, tightness, media, fittings, safety, care and best practices.
When are pneumatic calibration pumps the best choice?
When you need clean, sensitive pressure generation up to about 20/40 bar—e.g., for process and HVAC transmitters, gauge/absolute/differential devices.
Which pump types are available?
| Type | Typical range | Characteristics | Use case |
|---|---|---|---|
| Vacuum pump | 0…−0.95 bar | Fast vacuum, fine trimming | Absolute pressure, vacuum leak tests |
| Pneumatic pressure pump | −0.95…+20/40 bar | Coarse generation + fine adjuster | Low/mid-range transmitters & gauges |
| Combo pump | Vacuum & overpressure | Switchable, compact in a case | Versatile service work |
How do I achieve mbar-level stability?
- Use the micro volume adjuster (fine screw).
- Keep the system volume small (short hoses, few cavities).
- Minimize temperature drift; shield the setup from drafts/vibration.
What accuracy is realistic?
The pump generates pressure; your reference (digital gauge/transducer) sets the measurement accuracy. For pass/fail work aim for a TUR ≥ 4:1 (e.g., 0.25 % DUT → ≤0.06 % reference).
Can I test gauge, absolute and differential pressure?
Yes. For absolute pressure include the barometer. For differential use suitable manifolds/switching valves (equalize/isolate) with two ports.
Which media should I use?
Dry, clean air or nitrogen. Oil- and particle-free media extend valve/seal life and prevent contamination of the DUT.
How do I perform a leak/hold test?
Pressurize to the target → isolate → hold for a defined time → log the drift rate (e.g., mbar/min). Record temperature and compensate if needed.
What fittings/sealing concepts are common?
G 1/4 (BSPP), NPT, M20×1.5, 7/16″-20 UNF. Seal via O-ring/face seal (BSPP) or taper/cone (NPT/UNF). No tape on sealing faces; use approved compounds only.
Typical issues & remedies
- No pressure build-up → find leaks, check O-rings, are bleeds/bypass closed?
- Unstable reading → reduce volume, use the fine adjuster, equalize temperature.
- Slow approach → set correct inlet pressure, use bypass, check restrictions.
What safety aspects apply?
- Provide safe venting (silencer/vent line).
- Wear goggles/gloves; add hose strain relief.
- Operate within approved p/T and media; always depressurize before loosening.
What materials/seals are typically used?
| Component | Material | Note |
|---|---|---|
| Body/fittings | Aluminum / stainless steel | Weight vs. corrosion resistance |
| Seals | NBR / FKM / PTFE | Check medium/temperature compatibility |
How do I care for the pump?
- Periodically check/replace filters and seals.
- Keep interfaces clean; use dust caps.
- Service moving parts per the manufacturer’s instructions.
Do you offer complete kits & documentation?
Yes—pumps with reference gauge/sensor, adapter/hose kit, carry case and optional factory/DAkkS certificates; including operating/safety manuals.
Do you support selection & commissioning?
Yes—we define range/media, configure manifolds/adapters, supply accessories and assist with procedures and documentation.
