The Fluke Calibration P5500 Comparison Test Pump (formerly Pressurements) is designed for checking pressure measuring instruments against master test gauges, indicators or transducers. These cost-effective P5500 pumps enable easy, precisely controlled high-pressure generation, delivering a fast, economical solution for pressure instrument calibration.

The P5500 is available in three core models: hydraulic, pneumatic, and pressure/vacuum. Hydraulic models can generate pressure up to 60,000 psi (4200 bar), are compatible with a wide range of fluids, and include a high-quality screw press for fine pressure adjustments. Pneumatic models deliver pressure up to 3500 psi (220 bar), and feature both a screw press and needle valves for precise pressure tuning. The pressure/vacuum model offers a vacuum range of 24 inHg (800 mbar) and a pressure range of 300 psi (20 bar), with a high-quality needle valve for fine pressure adjustments.

All models of the P5500 Comparison Pumps include test port adapters, and support tool-free test connections that can be made without the need for PTFE tape or wrenches, simplifying setup and reducing calibration downtime.
