Do’s

Handle with care - The pump can be

damaged by common steel tools. 

Disassemble the pump in a clean area

and keep the area clean during 
maintenance. 

Cover the workbench with a clean cloth

or with paper towels. 

Change the towels on the bench as 

necessary to ensure the area is clean
during maintenance and assembly. 

Keep prying and scraping tools and

hammers used on C-9000 product 
separate from those used for other
maintenance tasks

Pry only with clean, new brass or 

plastic tools and pry in designated
areas only.

Tap lightly with clean plastic or rubber

hammers.

Lubricate the threads on screws and

bolts with an anti-seize compound or
with molybdenum disulfide grease. 

Tighten the bolts with torque wrenches

to the specified torque. 

Tighten the bolts in a crossing pattern.

Avoid touching the bearings with any

hard object.

Use the seal installation tool provided

when reassembling the pump.

Clean the pump with water and

approved liquid solvents. “Soft” 
abrasive cleansers are acceptable
(kitchen and bath cleansers that won’t
scratch.) 

Don’ts

Don’t

pry, tap, scratch, scrape or 

otherwise work on the pump or its 
components with steel tools. 

Don’t

assume that because it is steel you

can’t damage the pump in handling. 

Don’t

work on the pump in a dirty area. 

Don’t

work on a bench which is not 

covered. Hard particles imbedded in
the bench can cause damage to the
pump parts. 

Don’t

use dirty or damaged tools, or

those that might have hard particles
imbedded in them. 

Don’t

use steel prying tools.

Don’t 

pry with edges or corners of 

the tool.

Don’t

pry with broken or damaged tools.

Don’t

tap with steel tools or hammers.

Don’t

use hammers with imbedded 

particles in the hammer faces. Use
clean, new tools.

Don’t

assemble the pump without 

lubricating the bolt threads.

Don’t

tighten the bolts without using a

torque wrench. 

Don’t

tighten the bolts all the way in the

first attempt, and don’t tighten them in
a circular order. 

Don’t

attempt to remove the bearings

from the plates. The bearings can 
be easily broken and the plates 
damaged in the process. 

Don’t

attempt to install the seal without the

seal installation tool and instructions.

Don’t

clean the pump using abrasives 

or by bead or sand blasting. 

Don’t

burn the pump out in a furnace.
