Additel ADT937 Hydraulic High Pressure Calibration Pump (Oil)

The Additel 937 Hydraulic High-Pressure Calibration Pump is a hand operated pressure pump designed for calibrating pressure measuring instruments with phosphoric acid ester fluid and Skydrol oil in the range from 85% vacuum to 15,000 psi (1000bar). With the patented screw press technology, high pressures can be easily generated, increased, and decreased smoothly. A specially designed shut-off valve makes the pressure as stable as possible during calibration. With no check valve (non-returning valve), the ADT937 avoids the troublesome leakage issues that is usually experienced with hand pumps and allows for minimal maintenance. Two hand-tight quick connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The ADT937 is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators, or transducers in the laboratory.

Features:

• High Pressure: Generates pressure up to 15,000 psi (1,000 bar)

• Durable and Minimal Maintenance: Patented screw press technology, with no check valve (non-returning valve) inside that is usually used on troublesome hand pumps causing leakage.

• Easy-to-use High pressures can be generated easily, as well as increased and decreased smoothly.

• Hand-tight Quick Connectors Allows easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches.

Applications:

The Additel 937 is designed to generate pressure from 85% vacuum to 15,000 psi (1000 bar) for the application requiring accurate pressure testing and calibration. It can be used in calibrating pressure gauges, transmitters, or other pressure measuring instruments.
