Description
The 7194A benchtop pneumatic pressure pump is a dual pressure source which can be
adjusted and stabilized quickly and easily. With a long pump lever, high output pressures
can be reached and a high-quality screw press is incorporated to allow fine pressure
adjustment settings within 0.1 mbar (10 Pa). A pump isolation valve shuts-off the pump from
the system under pressure to keep the output stable under calibration.
A built-in gas-liquid trap protects the pump from moisture and dirt. Any residual liquid in the
pump will be vented out via the vent port which incorporates a hose connection to allow
collection of liquids. Two finger-tight connectors installed on the pump allow the user to
connect and disconnect devices’ under test, as well as reference gauges quickly and easily.
The 7194A is simple to operate, with features that make it ideal for calibrating pressure
transducers, precision pressure gauges, gauge comparison as well as many other pressure
instruments. It is particularly suitable for applications where high pressure is required without
the use of hydraulic pumps or nitrogen cylinders.
