Pneumatic Calibration Pumps

12 products

Pneumatic calibration pumps are designed for generating precise pressure or vacuum without requiring electrical power, making them ideal for field calibration of pressure instruments. They are used extensively in industries such as oil and gas, utilities, and manufacturing for testing and calibrating pressure gauges, sensors, and transmitters. Lightweight and portable, these pumps provide excellent control and accuracy, ensuring technicians can perform efficient and reliable calibration tasks on-site or in laboratory settings. Their safe, versatile design makes them an excellent choice when consistent results are required across a range of pressure measurement applications. By investing in quality pneumatic calibration pumps, businesses reduce downtime, improve accuracy, and extend the life of their critical pressure instruments.

Frequently Asked Questions

Even microscopic leaks in hoses or O-rings cause pressure decay, making it impossible to reach a stable calibration point. Professional servicing ensures the pump maintains a vacuum or pressure seal for high-accuracy comparisons.

The vernier allows for precise "dialing in" of specific pressure points. If this mechanism is worn or unlubricated, you lose the resolution required to calibrate high-precision digital gauges or transmitters.

Most models feature a selector valve for vacuum or pressure. We verify the integrity of this switching mechanism during calibration to prevent cross-contamination and ensure accurate negative pressure generation.

Moisture or oil in a pneumatic pump can damage the "clean" instruments you are testing. Regular professional cleaning and seal replacement prevent fluid ingress from previous contaminated site tests.

Annual servicing is recommended to replace wearing seals and verify stroke efficiency. Heavy field use in Australian mining or oil sectors may require 6-monthly checks to ensure mechanical reliability.

Yes. If your pump includes an integrated reference gauge, we calibrate it against our master standards to ensure your primary field reference is traceable and accurate.
