INSTALLATION, OPERATION and MAINTENANCE MANUAL

FOR PENBERTHY MODELS GL & GH JET PUMPS

1.0 About the Manual

This manual has been prepared as an aid and guide for personnel involved in installation or

maintenance. All instructions must be read and understood thoroughly before attempting any

installation, operation or maintenance.

Failure to follow any instruction could possibly result in a malfunction of the jet pump with

resulting sudden release of pressure, property damage or severe physical injury.

IMPORTANT: Penberthy does not have any control over the manner in which its jet pump is handled,

installed or used. Penberthy cannot and will not guarantee that a jet pump is suitable or compatible for

the user's specific application.

2.0 Introduction

2.1 Features and Specifications

Penberthy gas operated jet pump models GL and GH are designed primarily for exhausting,

evacuating, and priming using steam or air as the operating medium; and for pumping water

using steam as the operating medium. They can also be used with other gases as the

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.

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

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.
