The Split Manifold Kit enables you to convert the
Husky 307 Pump to a dual fluid inlet manifold, dual
fluid outlet manifold, or both. See Figs. 1, 2, and 3 for
some applications. To install the kit, see page 3.

manifolds.
System Explanation
In this installation, fluid is drawn from the supply container into one of the manifold inlets.
With the fluid needle valve (N) closed, the fluid
is pumped through side A and out to the tray.
Opening the air side needle valve (P) draws air
into the fluid return line so less fluid is returned
to the pump (side B) than is supplied to the
tray.
To circulate the fluid, close valves P and N.
To lower the fluid level in the tray, close valve
P and open valve N.
To raise the fluid level in the tray, close valve N
and open valve P.
This is a basic system. Additional equipment
such as solenoids and float valves can be used
for automated systems. See your Graco representative for details.

TWO FLUIDS TO TWO DESTINATIONS
Uses dual inlet and dual outlet manifolds.
System Explanation
Supplies two fluids, such as two colors of ink, to two
separate destinations. Use in installations where
surging does not cause a problem.

1:1 MIX RATIO (approximate)
Uses dual inlet and single outlet manifolds.
System Explanation
Mixes two fluids, such as antifreeze and water, in an
approximate 1:1 ratio. Minimum fluid output should
be in increments of 3 quarts to ensure an approximate 1:1 ratio. Lower output quantities may result in
an unequal mix ratio.
