Operation
Flushing
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 6.
Your fluid supplier should be able to tell you the rate at
which your fluid dries, or its contents settle during
non-use. Flush the pump frequently enough to prevent
the fluid from drying or settling in the pump and hoses
to prevent costly damage. Use a compatible solvent.
Refer to the Technical Data on page 11 and in the
separate displacement pump manual for a list of the
wetted parts.
If you are pumping water-based fluid, first flush with
water and then with a compatible solvent.
Water, or even moist air, can cause your pump to
corrode. Read and follow the Caution below.
CAUTION
Never leave water or water-base fluid in the pump
overnight. If you are pumping water-base fluid, flush
with water first, then with a rust inhibitor such as
mineral spirits. Relieve the pressure, but leave the
rust inhibitor in the pump to protect the parts from
corrosion.
Keep the Fluid Supply Container Filled
If your pump is running too fast, or accelerates quickly,
it is probably out of fluid. Shut off the air supply imme-
diately to prevent damage to the pump. Check the fluid
supply frequently and replenish it as needed. If the
fluid supply is empty, and air has been sucked into the
fluid lines, be sure to pime the pump again before
regular operation.
Shutdown
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 6.
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.
