Typical Installation
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. Wiper
rings and other accessory equipment for use with this
ram are listed in the
Accessories section on page 75.
Selecting a Location for the Ram
Refer to the Ram Mounting and Clearance Dimensions
drawings on page 78 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.
D Make sure there is sufficient overhead clear-
ance for the pump and ram when the ram is in
the fully raised position.
D If you are installing a vent hood, make sure
there is sufficient horizontal clearance for it.
D Make sure the air regulators for the pump and
ram are fully accessible.
D Make sure there is easy and safe access to an
appropriate electrical power source. The
National Electrical Code requires 3 feet of
open space in front of the electrical panel.
2. If you are installing a vent hood, make sure the
ram is installed or located near a connection to the
factory ventilation system.
Refer to the Ram Mounting and Clearance Dimen-
sions drawings on page 78 for ram mounting and
clearance dimensions.
3. You need to decide whether you will be bolting the
ram to the floor, or bolting it to a mobile platform.
4. If you bolt the ram to the floor, make sure:
D you will be able to level the base of the ram
using metal shims
D you have anchors long enough to prevent the
unit from tipping. Refer to the Dimensional
Drawings on page 76 for more information.
5. If you bolt the ram to a mobile platform, make
sure:
D
you locate the platform on a surface where it
won’t roll around.
D the ram and platform are stable in all operating
positions, so the ram won’t tip over.
