CONSTANT DELIVERY PUMPS Fig. 2 — Graphical symbol of type "C" pump (5V-10399-L). Fig. 3 — Graphical symbol of type "CG" pump (5V-10399-L). Over Twenty Sizes Up to 200 hp Oilgear Type "C" Constant Delivery One-Way Pumps are radial rolling piston fixed stroke units for pressures up to 3000 psi. The volume of fluid delivered depends upon the size of unit, the pressure rating and drive shaft speed. Fluid is discharged in one direction only. Directional con- trol valves can be used to reverse fluid flow. Flanged to each pump is an adjustable relief valve to protect fluid system against overload. Pumps are available for clock- wise, counterclockwise or reversing input shaft rotation. Oilgear Type "CG" Constant Delivery Pumps have the same radial rolling piston pumps, plus built-in gear pumps and relief valves for auxiliary or pilot valve operations. They're also available with suction, check and back pressure relief valves for supercharge purposes. On applications using repetitive constant speed cycles, these simple pumps will prove most economical. Where variable volume is essential and two or more pumps are needed for low cycle time, it's economical to use "C" or "CG" pumps with Oilgear variable delivery pumps. For example; hot plate presses often use high volume, 1100 psi, type "C" or "CG" pumps in combination with Oilgear low volume, 3000 psi, variable delivery pumps having automatic pressure unloading controls. All pumps deliver for fast closing and opening of press. The power saving controlled variable delivery pump maintains full static tonnage while the constant delivery pumps are bypassed or stopped.

Proven Power Pump Design Exclusive Power Saver The alloy iron cylinder, lined with anti-friction metal, rotates on a fluid film about the stationary alloy steel pintle pressed into the pump case. Ports and drilled passages in the pintle direct fluid to and from the cylinder bores. Exclusive, one piece, hardened and ground, alloy steel rolling pistons are closely fitted to radial bores in cylinder. A single spot of the lapped beveled surface on top of piston contacts the hardened and ground beveled surface inside the thrust ring. The balanced rotor and thrust ring assembly is mounted to the...
