The typical installation discussed below is only a guide
for selecting and installing system components and
accessories. Contact your Graco representative or
Graco Technical Assistance for help in designing a
system to suit your particular needs.
This air-powered ram extruder forces high viscosity
fluids into the intake valve of the fluid pump. Some
system accessories are discussed below. Accessories
for use with this ram are listed in the Accessories
section on page 66.
Selecting a Location for the Ram
Refer to the Ram Mounting and Clearance Dimensions
drawing (Fig. 7 on page 67) for ram mounting and
clearance dimensions.
When selecting a location for the ram, keep the follow-
ing in mind:
1. There should be sufficient space for installing and
using the equipment. Make sure:
there is sufficient overhead clearance for the
pump and ram when the ram is in the fully
raised position.
the air regulators for the pump and ram are
fully accessible.
2. You need to decide whether you will be bolting the
ram to the floor, or bolting it to a mobile platform.
3. If you bolt the ram to the floor, make sure:
you will be able to level the base of the ram
using metal shims.
you have anchors long enough to prevent the
unit from tipping. Refer to the Dimensional
Drawing on page 67 for more information.
4. If you bolt the ram to a mobile platform, make
sure:
you locate the platform on a surface where it
won't roll around.
the ram and platform are stable in all operating
positions, so the ram won't tip over.
System Accessories
Before you install the system you should be familiar
with the parts discussed below. For more information,
refer to Fig. 1, A Typical Installation, on page 7.
Typical Installation
Air and Fluid Hoses
When installing a system, make sure:
all air and fluid hoses are properly sized for your
system.
you use only electrically conductive air and fluid
hoses.
you ground your equipment.
the fluid hoses have spring guards on both ends.
To allow the gun freer movement, use a short whip
hose between the main fluid hose and the gun.
Air Line Modules
WARNING
PRESSURIZED FLUID HAZARD AND
MOVING PARTS HAZARD
The pump bleed-type master air valve
(C) is required in your system to relieve
air trapped between this valve and the
pump after the pump air regulator is
closed. Trapped air can cause the pump
to cycle unexpectedly, which could result
in serious bodily injury, including splashing in the
eyes or on the skin and injury from moving parts.
The following components are included with the mod-
ule:
Pump Bleed-type Master Air Valve (C) is required in
your system to relieve air trapped between it and
the air motor when the valve is closed (see the
WARNING above). Be sure the bleed valve is easi-
ly accessible from the pump, and is located down-
stream from the air regulator.
Pump Air Regulator (D) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump, but
upstream from the bleed-type master air valve.
Ram Air Regulator (not shown) controls the air
pressure to the ram.
Ram Air Supply Hose (H) connects the ram air reg-
ulator to the air manifold.
Air Manifold (F) divides the main air supply into
separate lines for the pump and ram.
