Operation
Running the Pump
Ensure that th
e hose material and the lubricant are
compatible w
ith the pumped fluid. Failure to do so
may cause inj
ury or premature hose failure.
NOTICE
Never thrott
le the pump, whether on the fluid inlet
or outlet si
de. This will cause damage. Do not
operate the
pump against a closed inlet or outlet
valve.
• Run the pum
passlowlyaspossibletoachievethe
desired re
sults. Measure the fluid inlet and outlet
pressure t
o verify that the pump is operating at the
designed p
ressure point.
• Do not ope
rate the pump motor above the full load
amperage
stamped on the motor nameplate. The
pump can b
e operated at low motor amperage.
• Keep the p
ump fluid inlet and outlet open and free
of obstr
uctions.
Dry Runn
ing
The pum
p can run dry without damaging the pump.
Howeve
r, pumped fluid normally provides a cooling
effect
to both the hose and the hose lube. Continuous
dry run
ning may reduce hose life.
Operating in Low Temperatures
NOTICE
Never operate the pump if the fluid inside the hose
is frozen. This will cause serious damage to the
pump.
If operating the pump at low temperatures, ensure
that the fluid being pumped does not freeze inside
the hose, especially during long periods of idleness.
Do not start the pump if the fluid inside the hose is
frozen. Ensure that the inlet line, the outlet line, and
the pump housing are heat-taped and insulated so
freezing does not occur.
Shutdown
Use the following procedure to stop the pump.
1. Flush the
fluidlinesandpumptoremovesolids
that may
accumulate in the line or hose. See
Flushin
g, page 20.
2. Shut off
the motor.
3. Isolate
any flushing fluid connections.
4. Close t
he fluid inlet valve.
5. If the p
ump will be out of service for more than
30 days
,seeStorage, page 19.
Storage
Follo
w this procedure to store the pump for more
than
30 days.
1. Remove the front cover drain plug to drain all
lubricant from the pump. Once the pump is
drained of lubricant, add a desiccant pack to
prevent moisture accumulation. Leave the drain
plug out until restoring the pump to service, to
prevent water from accumulating in the pump.
2. Remove the hose from the pump. See the Pump
Repair-Parts Manual.
3. Grease the bearings as needed.
4. Inspect the pump and re-crate it. Store the pump
in a clean, dry area that is free from extremes in
temperature.
