High pressure liquids and gases are potentially hazardous. Energy stored in these liquids and gases
can be released unexpectedly and with extreme force. High pressure systems should be assembled and
operated only by personnel who have been instructed in proper safety practices.

This manual provides the user with the information necessary to operate an MPG2-H Manual Pressure
Generator/Controller for Hydraulic pressure. It also includes additional information provided to help you
optimize MPG2 use and take full advantage of its many features and functions.
For those of you who “don’t read manuals”, go directly to Section 2.3 to set up your MPG2. Then go to
Section 3.2. This will get you running quickly with minimal risk of causing damage to yourself or your MPG2.
Then… when you have questions or start to wonder about all the great features you might be missing, get into
the manual!

additional explanations.
The DHI Manual Pressure Generator/Controller for Hydraulic Pressure (MPG2-H) provides a compact
and easy to use system for manually generating, setting and finely adjusting pressures between
atmosphere and 200 MPa (30 000 psi) in closed volumes. MPG2 is a standard pressure generation and
control component for working with DHI PG7302 piston gauges or liquid operated RPM4 reference
pressure monitors. MGP2 and RPM4 are available as a single, integrated pressure calibration instrument
designated E-DWT
The MPG2-H-HV has a larger displacement variable volume (7 cc rather than 3 cc) and is intended for
applications with higher test volumes to reduce variable volume stroke needed to generate the desired
pressure. The maximum working pressure of MPG2-H-HV is 100 MPa (15 000 psi). The MPG2-H
requires less variable volume torque and adjusts pressure more precisely.
