Maintenance
Carefully monitor your fluid supply. If your pump us
running too fast, or accelerates quickly, it is probably
out of fluid. Shut off the hydraulic power supply imme-
diately to prevent damage to the pump. If the fluid
supply is empty, and air has entered the fluid lines, be
sure to prime the pump again before regular operation.
Flush the pump frequently enough to prevent the fluid
from drying or settling in the pump and hoses to pre-
vent costly damage. Use a compatible solvent. Refer
to the Technical Data in the separate displacement
pump manual for a list of the wetted parts.
If you are pumping water-base fluid, first flush with
water and then with a compatible solvent.
Corrosion Protection
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure
on page 8.
CAUTION
To help prevent corrosion of the pump, never leave
the pump filled with water or water-base fluids, or air
during non-use. After flushing, flush the pump again
with a compatible solvent, such as mineral spirits,
relieve the pressure
, and leave a coating of solvent
in the pump and hoses..
Shutdown
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure
on page 8.
Always stop the pump with the displacement rod in the
down position. This prevents fluid from drying on the
displacement rod and damaging the packings when
the pump is restarted.
Relieve the pressure
whenever
you shut off the pump.
