m
Under no circumstances should these design ratings or application data be exceeded.
Exceeding design ratings or application data may cause bursting of steam jet pump, discharge
of live steam, objectionable noise and vibration, loosening of joints, leaks and suction flow
reversal, resulting in severe physical injury or property damage.
3.0 Inspection and Performance Confirmation
3.1 Receiving Inspection
Upon receipt of jet pump, check all components carefully for damage incurred in shipping. If
damage is evident or suspected, do not attempt any installation. Notify carrier immediately
and request damage inspection.
3.2 User's Rating Inspection
The user should confirm that:
1. The jet pump size (cast on side of body) and model designation (stamped on nozzle hex
flats) conforms to the description on the user's purchase order.
2. The operating conditions described in the purchase order agree with the actual operating
conditions at the installation site.
3. The actual operating conditions at the installation site are within the applications data
shown on the Penberthy Technical Data Bulletin or product proposal referred to above.
4. The materials of construction of the jet pump are compatible with both the contained fluid
and the surrounding atmosphere in the specific application.
m
If the size, model or performance data of the jet pump as received does not conform with any
of the criteria above, do not proceed with installation. Contact an authorized Penberthy
distributor for direction on how to proceed.
4.0 Installation
Note: The user should refer to Penberthy dimension sheets or Penberthy product proposal to obtain
dimensional information for specific size and model jet pump.
Check the exploded view Figure 3 for the location of operating, suction and discharge connections to
insure correct hook up.

4.1 Effect of Related Piping and Precautions
1. Penberthy gas operated jet pump models GL and GH may be installed and
operated in any position.
2. Jet pumps should be installed with pipe and fittings which provide minimum
resistance to fluid flow. Pipe line friction losses must always be a consideration
when estimating jet pump performance.
3. It is recommended that provisions be made for pressure gage connections near
the inlet, suction and discharge connections of the jet pump. If operating
difficulties are encountered at any time, it may become necessary to install
pressure gages to identify the problem.
4. Steam must not have over 20°F (-7°C) of superheat, or performance will differ
from that published on Penberthy Technical Data Bulletin or product proposal
referred to above.
5. When pumping liquids, suction piping should be sized so that the velocity of the
liquid does not exceed 4 feet per second. This is almost always automatically
obtained when the suction line is the same pipe size as the suction connection.
6. Install a valve in the suction line if it is desirable to:
a. Prevent contamination of suction fluid by the motive fluid at start up.
b. Prime a centrifugal pump.
c. Throttle suction flow.
7. When a gas operated jet pump is used to lift liquids by suction or vacuum, the jet
pump should be located as close to the level of the liquid as practical. However,
any liquid entrained into the jet pump, other than water when using steam as the
operating medium, may cause the jet pump to stop pumping, resulting in a
possible suction flow reversal.
8. Discharge piping should be sized as short as possible and with the least number
of turns and restrictions. Discharge piping friction losses must always be
considered when estimating jet pump performance. Increase discharge line pipe
size if necessary to minimize loss.
9. Do not impose system piping loads on a jet pump. The unit is not designed to be
a load bearing fitting.
10. All piping should be clean and free of foreign materials which could clog the jet
pump.

5.0 Operation
5.1 Pre-Operational Check
1. Assure that all installation procedures have been completed.
2. Assure that any restrictions in the discharge line have been removed.
3. Assure that any discharge line valves are fully open.
4. Assure that suction line valve, if installed, is fully closed.
5.2 Operating
1. Open the motive valve quickly.
2. Open the suction line valve, if any.
3. Regulate the discharge pressure as desired, to a value within the capability
published on Penberthy Technical Data Bulletin or product proposal referred to
above.
4. For pump priming applications, when evacuation is completed, close the suction
valve and immediately start the centrifugal pump. Then shut off the motive valve
to the jet pump.
6.0 Maintenance
Maintenance should only be undertaken by qualified, experienced personnel who are familiar
with this equipment and have read and understood all the instructions in this manual. Do not
proceed with any maintenance unless the jet pump has been relieved of all pressure or
vacuum, has been allowed to reach ambient temperature and has been drained or purged of all
fluids. Failure to return to ambient conditions may result in personal injury or property
damage.

7.0 Disassembly-Reassembly
m
Do not proceed with removal of jet pump from connecting piping unless the jet pump has been
relieved of all pressure or vacuum, has been allowed to reach ambient temperature and has
been drained or purged of all fluids. Failure to follow these instructions may cause personal
injury or property damage.
The jet pump Models GL and GH are made up of two parts (see Figure 3), a nozzle (61) and a body
(11) which are held together by a straight right hand mechanical thread, closing the face seal between
these parts.
To disassemble the unit, first attach a short piece of pipe to the suction connection as a handle, then
grip the nozzle flats and rotate in a counterclockwise direction.
When ready to reassemble unit, be sure the seal face of the nozzle and body are free of foreign
material and raised metal due to nicks. A non-hardening pipe seal compound may be applied to the
threads to further promote sealing. Thread the body back on to the nozzle turning in a clockwise
direction.
8.0 Disposal at End of Useful Life
Penberthy Jet Pumps are used in a variety of fluid applications. By following the appropriate federal
and industry regulations, the user must determine the extent of preparation and treatment the Jet
Pump must incur before its disposal. A Material Safety Data Sheet (MSDS) may be required before
disposal services accept certain components.
Metal, glass and polymers should be recycled whenever possible. Refer to order and PV&C - Black
Mountain Material Specification sheets for materials of construction.
