Built for ultra-high-pressure calibration, this benchtop test pump drives 0 to 40,000 psi through a 9/16-inch autoclave fitting, running on water as the pressure medium. A dual-piston design fills large workloads and then fine-tunes pressure, while an isolation valve holds the calibration volume steady and protects the check valve for stable, low-maintenance runs.
