Installation on a Ram
(Carbon Steel or Aluminum Plates)
Installation
Reference letters and numbers in the text refer to Figs.
1–4 and the Parts Drawings on pages 14–15.
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate your
fingers. When the pump is operating and
when raising or lowering the ram, keep
your fingers and hands away from the priming
piston and the lip of the pail.
WARNING
To reduce the risk of serious injury, whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 5.
1. Relieve the pressure.
2. Install the wiper plate (A) onto the pump intake (B),
with the wiper plate vent handle (C) facing the front
of the ram. Secure by tightening the setscrew (3).
See Fig. 1.
3. The wiper plate is supplied for use with 19 liter (5
gallon) straight sided pails, but it can be easily
modified for use with tapered pails. See steps a
and b.
a. To use the wiper plate with tapered pails,
the large spacer (19) must be removed. Work-
ing from the bottom, use a screwdriver to pry
the spacer loose. Work it upward so it is com-
pletely above the flange (D) of the wiper plate.
See Fig. 2. Next, by hand, angle the spacer
and work it off the plate, pulling it down over
the flange and bottom wipers (E). See Fig. 3.
Save the spacer, as it is required for other
applications.
b. To reinstall the spacer for use with a
straight sided pail, first make sure the large
diameter of the spacer (19) is facing down.
Work the spacer up over the wiper plate by
hand, so it is completely above the flange (D)
of the wiper plate. See Fig. 3. Then, working
from the top, use a screwdriver to position the
spacer between the flange (D) and the wipers
(E). See Fig. 4.
4. Connect a 610 mm (24 in.), 1/4 in. (6.3 mm) OD
nylon tube (F) with a 1/8 npt(f) fitting (H) from the
ram’s air assist tube fitting (G) to the air assist
check valve (21) on the wiper plate.
5. Refer to the separate ram and pump manuals for
set-up and operating instructions.
Maintenance
If the wiper plate does not come out of the pail easily
when the pump is being raised, the air assist tube (F),
fitting (H), and check valve (21) may be plugged. This
prevents air from reaching the underside of the plate to
assist in raising it from the pail.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 5.
Relieve the pressure. Refer to the Parts Drawings on
pages 14–15 and disassemble the air assist check
valve as shown. Clear the tube (F) and the port in the
wiper plate. Clean all parts of the check valve assem-
bly, and reassemble.
