Shutdown and Care of the Pump

Shutdown and Care of the Pump
1. Follow the Pressure Relief Procedure on page 36.
2. Set the Ram Director Valve (BC) to DOWN, and
lower the Ram (AA) to the desired position for
shutdown. If using a tandem system, perform this
step on both units.
3. Set the Ram Director Valve (BC) to neutral.
4. Stop the Pump at the bottom of the stroke to prevent
fluid from drying on the exposed displacement rod
and damaging the throat packings. See the E-Flo iQ
Supply System Operation manual for information
about jogging the Pump. See
Related Manuals on
page 3.
5. Always flush the Pump before the fluid dries on the
displacement rod. See the E-Flo iQ Supply System
Operation manual for steps to flush the pump.
Change Drums
If the Platen (AD) does not come out of the pail easily
when the Pump is being raised, the air assist tube (AT)
or check valve (416) may be plugged. A plugged valve
prevents air from reaching the underside of the plate to
assist in raising it from the pail.
1. Turn off power to the Electric Driver (AB):
a. Turn the black Power Junction Box Switch (AK)
OFF. See F
IG
. 30.
b. If using a Tandem Ram Supply System, turn the
black Disconnect Switch (AZ) OFF on the Ram
Supply Unit that requires a drum change only.
See F
IG
. 30.
NOTICE
To prevent damage to the pump from rust, never
leave water or water-based fluid in a carbon steel
pump overnight. If you are pumping a water-based
fluid, flush with water first. Then flush with a rust
inhibitor, such as mineral spirits. Relieve pressure,
but leave the rust inhibitor in the pump to protect
parts from corrosion.
Keep hands away from the pump inlet to prevent
serious injury from moving parts.
