INSTALLATION
Mounting the Pump (Model 207–279 Ram)
NOTE: The Pump Selection Chart on page 3 lists pumps
commonly mounted on this ram. Installing other
pumps on the ram may require alternate parts,
which are packed in separate plastic bags. For
information, contact your Graco representative
or Graco Technical Assistance at
1–800–543–0339.
Mount
the pump as follows. Refer to the T ypical Installa -
tion
on page 4.
1. Remove the mounting plate (58); it is not required for
those pumps listed in the chart on page 3. Position
the mounting brackets (57) so that the top of the
pump
will clear the support beam (3). Set the pump
on the mounting brackets (57) with the air inlet
toward
the ram director valve (4). Attach the pump to
the mounting brackets with the screws (27) and
washers
(26) provided.
2. Remove the four screws (25) and washers (31)
holding
the standard seal plates (62) to the ram plate
(63) and remove the top seal plate (62) and seal (56).
Leave the bottom seal plate (62) and gasket (61) in
place.
See Fig 1.

Bulldog, and 55:1 ratio King standard extrusion
pumps,
slide the top seal plate (62) up over the pump
intake valve and push the seal (56) onto the pump
intake
housing. Then continue with step 4.
For 10:1 ratio Bulldog and 20:1 ratio King pumps with
a flanged intake housing, discard the top seal plate
(62) and seal (56). Remove and discard the bottom
seal plate (62). Align the holes in the intake valve
flange with those in the gasket (61) and ram plate
(63).
Then continue with step 4.
4. Loosen the mounting bracket setscrews (35), and
carefully
lower the pump until the intake valve is be -
low
the gasket (61), then tighten the setscrews.
5. If applicable for your installation, push the seal (56)
down
firmly against the bottom seal plate (62).
