Operation
Start and Adju
st the Pump
1. Load tote. See Loading the Tote, page 25.
2. Be sure the pump is off. Set the ram down air
pressure to 10 psi (0.06 MPa, 0.6 bar).
3. Use the ram jog button to lower the ram until it
just contacts the product in the tote.
4. If the ram plate is inside the tote, inflate the seal.
5. Operate the pump speed to the slow (turtle)
speed setting. If necessary, adjust the pump
pressure.
6. Operate the ram control to the down position.
NOTE: Incr
ease air pressure to the ram down
pressure r
egulator if the pump does not prime
properly w
ith heavier fluids. Decrease air
pressure i
f fluid is forced out around the inflated
ram plate s
eal.
7. If not alr
eady done in step 4, inflate the seal
when the r
am plate is below the lip of the tote.
Change Tote
Excessive air pressure in the tote could cause the
tote to rupture, resulting in serious injury. The ram
must be free to move out of the tote. Never use
blowoff air while the ram seal is inflated.
1. Operate the pump speed selector to off.
2. Raise the ram out of the tote:
a. Operate the seal selector to deflate. Once
the seal is deflated, operate the seal selector
switch to pause.
b. Raise the ram out of the tote.
NOTE: The blowoff air comes directly from
the unfiltered facility air supply
c. If the ram raises the tote off of the ground,
press the air assist (blowoff) button to break
the vacuum between the ram plate and
product.
d. If ram does not raise, increase ram up
pressure.
e. When the ram plate is free of the tote and the
ram reaches its full height, operate the ram
selector to the ram hold position.
3. Remove the empty tote.
To reduce the risk of injury, including pinching
fingers, while cleaning material from the ram
plate, relieve pump pressure before using tools
to clean.
4. Inspect r
am plate and, if necessary, remove any
remainin
g material or material build-up.
a. If used, open all user-supplied system fluid
drain valves that are downstream of the
pumps.
b. Use a tool to remove material build-up.
5. To empty another tote, perform the steps of
Loading the Tote, page 25.
