CAUTION
WIPER SEAL LUBRICATION
The wiper seal must be lubricated with a compatible
sanitary grease to ensure minimal friction between the
tube, plate and sides of the container. The sides of
the container will be lubricated by the material. Fail-
ure to lubricate the seal will result in wiper seal dam-
age.

Operation
309549B 9
Operation
Your new sanitary ram plate offers greater versatility and
value-added features over conventional versions:
•When deflated, the seal retracts inside the outer
diameter of the plate weldment.
•The plate has no loose parts to be misplaced during
cleaning.
•The seal can be removed with little effort.
•The weldment is constructed of 316 SST and con-
tains a universal mount for pumps.
The seal pressure must be adjusted to meet your pro-
cess requirements. Process material viscosity, ram
pressure, drum diameter, and pumping rate are key fac-
tors in determining the proper seal pressure.
Typically,
for standard 55-gallon drum applications, set the
pressure regulator between 10 and 14 psi.
The max-
imum pressure rating for the seal is 25 psi. The safety
relief valve is set to 20 psi to prevent over-pressuriza-
tion.
Use trial and error to find the right combination of ram
pressure and seal pressure. To minimize seal wear, use
the lowest possible air pressure while still preventing
material blow-by.
•If both ram and seal pressure are too high, the seal
will fail prematurely.
•If ram and/or seal pressure is too low, the pump may
not prime or the drum will not be sealed properly.
Pressure Relief Procedure
1. Relieve the pressure as explained in your separate
pump or system manual.
2. Turn off the air to the ram.
Sequence of Operation
Initial Conditions:
1. The ram is fully raised.
2. The seal is deflated.
3. The seal is lubricated with appropriate sanitary
grease.
4. The pump is off.
At the Operator Control Station:
1. Position a new process drum under the ram. If bag
liner is present, secure top of bag to outside of
drum.
2. Slowly lower the ram plate into the drum.
3. When plate to material contact is made, inflate the
ram seal.
4. Turn the pump on.
5. When drum is empty, turn pump off.
6. Deflate ram seal.
7. If a vacuum has formed between the ram plate and
the drum, push the button on the blow off valve to
activate blow off.
8. Raise plate out of drum.
WARNING
Read the warnings on page 3.
The blow off valve is typically used with highly vis-
cous materials.

Cleaning
10 309549B
Cleaning
Flush the unit before taking it apart for cleaning. Flush
the system with an over-sized container of cleaning
solution around the ram plate. Run the pump at low
speed and circulate the cleaning solution through the
system.
Flushing Safety
To reduce the risk of fluid injection injury, static sparking,
or splashing, follow the Pressure Relief Procedure (page
9) and remove the spray tip (spray guns or spray valves
only) before flushing. Hold a metal part of the gun firmly
to the side of a metal pail and use the lowest possible
fluid pressure during flushing.
Remove the Inflatable Seal
The inflatable seal must be removed from the
bottom
of
the ram plate. The bottom lip diameter is smaller than
the top.
Do not use sharp objects to remove the
seal.
Clean the seal and the ram plate.
1. Disconnect the air tube (A) from the seal fitting. The
fitting must be removed to allow passage of the
stem through the plate access tunnel.
2. On the side opposite the stem and starting with the
top edge, peel the seal downward. The bottom side
of the plate has a smaller diameter than the top to
facilitate easy removal and installation.
3. Continue peeling the top edge of the seal along the
diameter of the plate. Note that the top edge is
twisted downward. Once the seal is loose, gently
pull the stem from the tunnel.
