Chemical Supply
The pump can be bolted to a wall or skid by the attached
bracket.
NOTE:
The pump must always be mounted vertically.
If you have an application, or mounting configuration,
that requires installation in a manner different than
depicted in F
. 1, please contact your Graco distributor
for assistance.
NOTE:
A Y-strainer (G) or chemical filter is required
before the pump inlet. This will keep debris from the
tank from reaching the pump seals. Fluid filters are
available from Graco.
