Install the 6 in. or 12 in. nipple into the MPG1.

Screw in the glands loosely by hand. Tighten the

gland with a 5/8 in. wrench or crescent wrench.

Install a DH500M to 1/8" NPT male adaptor in

the DUT if necessary: The 1/8 in. NPT male

adaptor can be used to connect the remaining thin

5 in. nipple to DUTs with 1/8 in NPT female ports.

If you intend to use the adaptor, wrap Teflon

thread tape around the NPT threads three times

and install it into the DUT.

Install the Device Under Test (DUT). The DUT

will be connected to the test line with the

remaining thin 5 in. nipple. This nipple can be

installed either in the 3-way tee, or in the port on

top of the MPG1. The tube can be slightly bent if

necessary. Install the nipple in the desired

location. Tighten the gland in the tee or MPG1, but

do not tighten the gland that connects to the DUT.

Plug the open test port: There is an open test port

either on the top of the MPG1, or on the 3-way tee.

Insert the stainless steel plug into a gland. Insert the

plug and gland into the open port. Do not tighten.

Prime the system, tighten fittings: Pump fluid

through the nipples by using the MPG1. See the

appropriate section of the MPG1 Operation and

Maintenance Manual for this procedure.

sure that all air is purged from the test lines.

There are 3 loose fittings: one on the DUT, one on

the RPM4 or PG7302, and the other on the plug.

Tighten each of the loose fittings when oil without

bubbles begins to flow through it.

The maximum operating pressure of the variable volume is

100 MPa (15 000 psi) in MPG1-100M and 200 MPa (30 000 psi)

in MPG1-200M. Do not generate pressure greater than the

maximum operating pressure.

High pressure fluids are potentially hazardous. Energy

stored in pressurized fluids 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.

ALWAYS use external tubing and fittings rated for

pressures equal to or greater than the maximum pressure which

MPG1 will be used to generate.
