PUMPS
|
| APPLICATIONS |
| Pumping for
aeration, agitation, filtration,
recirculation, spraying, transfer
in the following industries: |
| • Plating |
| • Electronics |
| • Photo
Processing |
| • Chemical
Processing |
| • Water
Treatment |
|
| FEATURES |
| • Virtually
maintenance free |
• Optimum
chemical resistance with choice
of CPVC,
Polypropylene, or PVDF (Solef) |
| • No
metal in contact with fluid
being pumped |
| • Seal-less
design eliminates leaking, costly
seal replacement and downtime |
| •
Viton “O” ring and
cover seal allows mounting in
liquid, or with inlet extension |
| • No
pump bearings allows pump to
run dry without damage and to
handle abrasives and slurries |
| • Non-overloading,
continuous duty totally enclosed
motor |
| • Teflon
fume barrier protects motor
end bell and bearings from corrosion
caused by vapor or fumes |
|
|
|
TYPICAL INSTALLATIONS
Marathon Pumps are designed to have
liquid end immersed in fluid being
pumped, assuring immediate pumping
on start-up and eliminating need for
priming. Inlet extension may be used
when pump is required to empty deep
tanks or for sump service (fig.2). |
 |
|
In-tank mounting.
Eliminates potential for spillage
of precious metals or corrosive
chemicals. Priming not required
when fluid level covers pump
discharge port. |
| Inlet extension
may be utilized when Marathon
Pumps are used as Sump Pump
or to empty or transfer from
deep tanks. Refer to adjacent
chart for maximum inlet extension. |
| Outside mounting
is often used where tank space
is limited, on fume scrubbers,
or to isolate pump and motor
from direct effect of corrosive
fumes in tank. Refer to Form
227 (included with pump) for
recommended plumbing methods. |
