CHAPTER 5
Servicing the Pump
The service procedures contain step-by-step instructions,
and most include illustrations to help explain how to ser
-
vice the equipment. Service instructions cover how to re
-
place parts during scheduled or unscheduled mainte
-
nance, and also include preventive maintenance proce-
dures to help ensure trouble-free operation. Refer to the
illustrations in the chapter, plus the engineering draw-
ings in Chapter 5, to identify parts.

Service tips
Review the safety precautions in Chapter 2 and the
general maintenance tips at the beginning of this chap
-
ter before starting any maintenance or service work. If
you have questions about any service, contact Flow
Technical Service.
•
Inspect the equipment every day before operating it.
If you see any problem, refer to the troubleshooting
guide and related service procedure(s).
•
Read and understand each service procedure before
starting any work. Pay particular attention to the pre
-
cautions in the service procedures.
•
Maintain records of service performed on the ma
-
chinery. This will provide valuable information to
help you restock spare parts.
•
If applicable, turn off the electrical power and re
-
lieve system pressure before starting any service. If
you must perform a service procedure while power
to the equipment is on, or while the system is pres
-
surized, take extra precautions to avoid injury.
•
Handle critical parts with care and avoid scratching
or denting the high-pressure water system compo
-
nents. Routinely check for loose bolts or wire
connections.
•
Protect all machined and lapped mating surfaces
against nicks, scratches, and burrs. Carefully work
out any damage to seal wiping surfaces, or seal dam-
age and leaks will be a recurring problem.
• Do not use a substitute for the fluids, sealants, and
lubricants recommended by Flow. Clean off grease
fittings before connecting grease gun to avoid inject-
ing dirt-filled grease into the bearings.
•
New bearings are frequently packed with only a light
shipping grease. Be sure they are properly lubricated
before operation.
•
Make every effort to find a clean service area. Do
not tear down parts in the same area where you are
cleaning parts. Airborne dirt and abrasive will seri
-
ously shorten component life.
•
Only clean parts with fresh, clean solvent that does
not leave a residue (such as Citra-safe or isopropyl
alcohol). Flow recommends that you set up a dedi
-
cated solvent tank for these critical parts. Contami
-
nation from other industrial parts will seriously
shorten component life.
•
Carefully clean and blow out all parts being reassem
-
bled. Do not use paper towels. Do not create air
-
borne dust.
•
Check around the equipment for parts, tools and
rags; remove them before starting the equipment.
