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.

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.

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.

Installation

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.

Connect the Fluid Output Lines

Connect electronically conductive fluid hoses to the pump outlet fittings. Tighten all of the fittings.
