Specifications; Installation; Location; Connect The Fluid Supply Lines - Graco 965660 Instructions And User Manual

The following chart gives specifications for the Mini-Cat
pumps, using No. 10 weight oil. The volumetric ratio is
expressed as the proportion of the volume of fluid of the
primary pump compared to the volume of fluid of the
secondary pump.

The Typical Installation drawings (Figure 1 and Figure
2) are only guides to setting up the complete Variable
Ratio Mini-Cat system. For assistance in designing a

Connect grounded fluid hoses to the 3/4 npt(f) pump
inlet fittings. If the unit will be pressure fed from sepa-
rate supply units, install a fluid pressure gauge at each
inlet.

For example, Model 965660 has a minimum volumetric
ratio of 1:1. At this setting the primary and secondary
pumps combined will deliver an output of 1.1 GPM (4.2
liter/min). The minimum volumetric ratio for Model
965660 is 1:1 and the combined output at that setting is
0.7 GPM (2.6 liters/min).

NOTE:
The pressurized fluid supplies must not exceed
1/4 of the operating fluid pressure of the pump. Pres-
sure above that level will feed right through the pump
and improper rationing will result.

Connect the Static Mixer

Connect a static mixer to the 1/2 npt(m) manifold outlet.
Connect a grounded fluid hose and spray gun to the end
of the static mixer. Tighten all the fittings.
