Uneven ram cylinder movement.
1. Ensure that the ram cylinder down pressure is not
excessive. Generally, no more than 1.0 bar (15 psig) is
required to move the ram cylinders in the downward
direction.
2. Check to determine whether or not the ram cylinder
air hoses are connected properly. Refer to airline
schematic if the ram cylinder air hoses are not
connected properly, the ram cylinders will fill
unevenly, causing the ram cylinder movement to
be inconsistent.
3. Check for cylinder mis-alignment that could be
causing binding. If so, determine if cylinders or
cylinder mounting could be causing an issue.
4. Make sure that air cylinder stops are adjusted
correctly. The adjustment screws are located in top
and bottom of cylinders.
Pump runs but little or no product flows.
1. Check for pump cavitation; slow pump speed to
allow thick material to flow into liquid chambers.
2. Check for sticking ball check valves. If material being
pumped is not compatible with pump elastomers,
swelling may occur. Replace ball check valves and
seats with proper elastomers. Also, as the check
valve balls wear out, they become smaller and can
become stuck in the seats. In this case, replace
balls and seats.
NOTE: Heavy check balls such as PTFE work best.
(Saniflex or Wilflex are considered light)
3. Check to ensure that there is sufficient air pressure
supplied by the ram down regulator on the control
panel.
4. Slow down pump to allow it to prime. Do this by
reducing air pressure to the control box. If high
discharge pressure is needed add a needle valve
right on pump inlet to reduce air flow.
Excessive drum contents leaking past gaskets.
1. Ensure that the correct gasket size is being used in
accordance with the drum size.
NOTE:The gaskets are NOT designed to completely
seal against sides of drum. Under normal operating
conditions, there will be some weeping of drum
contents.
After evacuating drum contents, ram cylinders are
struggling with upward movement.
1. Check to determine whether or not drum vent
button is activated. This will inject air under the
ram plate and break the vacuum caused when
removing the ram plate from the drum.
2. Verify "Ram Up" pressure is sufficient.
Pump air valve freezes.
1. Check for excessive moisture in compressed
air. Either install a dryer or hot air generator
for compressed air. Alternatively, a coalescing
filter may be used to remove the water from the
compressed air in some applications.
Air bubbles in pump discharge.
1. Check for ruptured diaphragm.
2. Check tightness of outer pistons.
3. Check tightness of fasteners and integrity of
o-rings and seats, especially at intake manifold.
4. Ensure pipe connections are airtight.
Product comes out air exhaust.
1. Check for diaphragm rupture.
2. Check tightness of outer pistons to shaft.

of pump. A 64 mm (2-1/2”) or
76 mm(3”) hose issuggested for best
performance.
Step 3
Check pump inlet air supply to
ensure that regulator is set to less
than the maximum of 8.6 bar (125
psig).

WILDEN PUMP & ENGINEERING, LLC 10 WIL-12071-E-01
Step 4
Move drum into position under ram
assembly, ensuring that the drum
guides on the bottom of the frame
stop the drum directly centered
under the plate.
Step 5
Check to ensure the proper gasket set is
installed for the drum being unloaded.
NOTE: The larger gasket included in the
gasket set should be approx. 1⁄2” to 1”
larger than the drum diameter and the
smaller gasket should be the same size
as the drum diameter.
In some drum types
such as conical drums or large diameter
pumps, all three gaskets sets should be
installed. The largest gasket should be
placed between the two smaller sizes. For
conical drums with narrow bottoms, the
small gasket should go on the bottom.
The gaskets are NOT de signed to com-
pletely seal against sides of drum. Under
normal operating conditions, there will be
some slight weeping of drum contents.
Step 6
Remove the drum lid to expose product
being pumped and hook drum retainer
hooks over upper edge of the drum. If
a plastic drum liner is used, the liner
should be draped over the drum lip and
then held down with same clamp that
is used to hold the drum lid. Tighten
drum retainer hooks to secure the drum
in the down position during operation.
When adjusted and tightened properly,
the drum should not move. The hook
can be placed on a different chain link if
further adjustment is needed.
Step 7
To active or reset the DUS unit, press the
green reset button any time the E-stop has
been pushed or the air supply has been
interrupted. NOTE: It is not necessary to
reset (start) the unit before each use, only
after the air supply has been interrupted.
Note: the red E-stop button is a safety fea-
ture that will stop the unit at any time in
operation. It is recommended you press the
E-stop any time the unit is left un-attended to
prevent accidental use of the DUS.
Step 8
When moving the ram in the down direction,
stand towards the right of the unit and grab
the ram plate support rod with your left
hand to guide the ram plate into position.
Step 9
To begin process of adjusting RAM
DOWN air supply, first set regulator

Step 10
To move the ram plate down onto the
product surface, pull the red lever to the
down position. This will take several
seconds as the pneumatic cylinders
come up to operating pressure. Ideally,
the pressure should be set so that the ram
plate stops automatically when coming
into contact with product surface.
Step 11
Check RAM UP air supply and
ensure that regulator is set for
normal operation (ram lifting speed).
Ideally, the pressure should be set
so that the ram plate will slowly
move upward and out of the drum.
Never exceed 5.5 bar (80 psig).
Step 12
