7 REMOVAL - DISASSEMBLY - REASSEMBLY

IMPORTANT

Do not proceed with removal of the 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 could result in personal 
injury or property damage.

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 the 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 the nozzle 
turning in a clockwise direction.

8 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 
relevant technical data sheet for materials of 
construction.

we may assist you more effectively, please have 
as much of the following information available 
as possible when you call:
- Model number
- Name of the company from whom you 

purchased the jet pump

- Invoice number and date
- Process conditions (pressure, flow rates, tank 

shape, etc.)

- A brief description of the problem
- Troubleshooting procedures that failed

If attempts to solve your problem fail, you may 
request to return your jet pump to the factory 
for intensive testing. You must obtain a Return 
Authorization (R.A.) number from Emerson 
before returning anything. Failure to do so will 
result in the unit being returned to you without 
being tested, freight collect. To obtain an R.A. 
number, the following information (in addition to 
that above) is needed:
- Reason for return
- Person to contact at your company
- 'Ship-to' address

There is a minimum charge for evaluation 
of non-warranty units. You will be contacted 
before any repairs are initiated should the cost 
exceed the minimum charge. If you return a 
unit under warranty, but it is not defective, the 
minimum charge will apply.
