Specifications of Hydra–Cat H.P. Pumps
The following chart gives specifications for the Hydra-Cat
H.P. 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.
Ratio
Air Motor Assembly Min
Part No.
Premier 965481 1.50
Premier 965479 2.00
King 965477 1.00
King 965478 1.50
King 965466 3.00
Note: All Output Pressures Limited To 5000 PSI By Integral Pressure Relief Valves
Note: Pressure outputs calculated at 100 PSI Air Pressure for Premier and 90 PSI Air Pressure for King
Note: Volume outputs calculated at 40 cycles per minute.
The Typical Installation shown is only a guide to setting up
the complete Hydra-Cat H.P. system. For assistance in
designing a system to suit your particular needs, contact
your nearest Graco representative.
NOTE: The reference numbers and letters in the text
correspond to the numbers and letters in the drawings.
Location
Sit the proportioner on a flat floor surface.
Connect the Fluid Supply Lines
Connect the grounded fluid hoses to the pump inlet fittings
(P, R). If the unit will be pressure fed from separate supply
units, install a fluid pressure gauge at each inlet.
NOTE: The pressurized fluid supplies must not exceed 1/4
of the operating fluid pressure of the pump. Pressure above
that level will feed right through the pump and improper
rationing will result.

Installation

For example, Model 965477 has a minimum volumetric
ratio of 1:1. At this setting the primary and secondary
pumps combined will deliver an output of 3.0 gpm. The
maximum volumetric ratio for Model 965477 is 3:1 and the
combined output at that setting is 2.0 gpm.
