Calibration Test Pumps are precision tools used to generate pressure or vacuum for the accurate calibration and testing of pressure measurement instruments, such as pressure gauges, transmitters, sensors, and switches. These pumps are essential in ensuring the reliability and accuracy of instrumentation across various industries, including oil and gas, power generation, manufacturing, pharmaceuticals, and laboratory environments.

Available in both pneumatic (air or gas) and hydraulic (liquid) versions, calibration test pumps allow users to create controlled pressure environments—from vacuum to very high pressures—making them suitable for a wide range of calibration needs. They are typically used alongside reference gauges or digital calibrators to verify or adjust the readings of pressure instruments to meet industry standards and regulatory requirements.
