Pressure / Process Calibration Equipment Additel 938 Hydraulic High Pressure Calibration Pump Generate 85% vacuum to 15,000 psi (1,000 bar) pressure Oil-free pressure instruments Minimal maintenance Easy-to-use Three pressure ports Hand-tight quick connectors OVERVIEW The 938 Hydraulic High Pressure Test Pump is specially designed for calibrating oil-free pressure measuring instruments in the range of 85% vacuum to 15,000 psi (1,000 bar). All parts used in the pump have been carefully cleaned to remove oil. The pump uses water as the media. With the patented screw press technology, high pressures can be easily generated, as well as 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 938 avoids the troublesome leakage issues that is usually experienced with hand pumps and allows for minimal maintenance. Three hand-tight connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The 938 is an ideal comparison test pump for calibrating oil-free pressure measuring instruments such as test gauges, indicators or transducers in the laboratory. High Pressure Generates pressure up to 15,000 psi (1,000 bar) Durable and Minimal Maintenance Patented screw press technology, without nonreturning valve inside that is usually used on troublesome hand pumps. Easy-to-use With the patented screw press technology, high pressures can be generated easily, as well as increased and decreased smoothly Extremely Low Leakage Patented screw press technology replaces troublesome check valves (non-returning valve) in most hand pumps which practically eliminates leakage. Hand-tight Quick Connectors Allows easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches.
