The 917 Pneumatic Pressure Test Pump is a hand operated pressure pump designed to generate pressure from95% vacuum to 1,000 psi (70 bar). A high-quality screw press is designed for fine pressure adjustment, with anadjustment resolution up to 10 Pa (0.1 mbar). A specially designed shut-off valve makes the pressure as stable aspossible during calibration. A built-in gas-liquid isolator protects the pump from moisture and dirt to reduce the needfor maintenance. The 917 can be special ordered to comply with oxygen free applications. Two hand-tight quickconnectors installed on the pump allow easy connecting and disconnecting to the test pump without the need forPTFE tape or wrenches. The 917 is an ideal comparison test pump for pressure instruments calibration.
