2 An air piston drives asmaller diameter plunger or piston to provide a pressure pressure ratio is the method of determining maximum outletpressure available. Hydraulics International model numbersreflect the nominal pressure ratio of the International LIQUID PUMPS will cycle automaticallywhen compressed air is first applied to the drive. It will startcycling at its maximum speed thus producing maximum fluidflow. At this stage, the pump is acting as a transfer pump, fillingthe pressure system with fluid.

3 As resistance increases in thesystem (creating backpressure to the pump), the pump willdecrease its reciprocating action. Backpressure in the systemfinally balances with the incoming air drive pressure times theratio. At this point, the pump will stall and maintain pressurewithout consuming any energy. If there is further demand on thesystem for flow, the pump will automatically start cycling again. Air Drive line lubrication not required. Self-priming for immediate operation. Compatible with all hydraulic fluids, plain water, distilled &deionized water, solvents, mild chemicals and most liquefiedaerosol type gases.

4 Range of models to provide up to 80,000 psi intermittentoutput pressure. Stainless steel hydraulic body, check valves, and trim arestandard, except -4 and -7 models. Alternative gases that can drive the pump include nitrogen,vapor from liquefied gas, pipeline natural gas and sournatural gas with proper modifications. Offer a wide range of standard modifications. Hydraulic pressure is held without energy consumption. Explosion proof .. requires no electrical power orconnections. Intrinsically safe. Compact, lightweight and weatherproof.

5 Easy to adapt automatic controls. Contamination tolerant. Outlet stall pressure pre-determined by the air driveregulator. High pressure capability - up to 80,000 psi. Ideal for stop-start applications under full load. Easy to install and 1. CROSS SECTION OF MODEL 5L-SS-RATIO3 HYDRAULICS INTERNATIONAL, INC.(818) 407-3400 TYPICAL APPLICATIONS HYDROSTATIC TESTING:Any component that is made to hold LIQUID or gaspressure needs to be carefully tested after manufactureor repair to verify its integrity, and/or to calibrate it. DRIVEN PUMPS can simplify this requirement in abroad range of industries.

6 CLAMPING-PRESSING-RELEASING:Hydraulic cylinders or rams that are required to maintainan output force without movement for long periodsneed a hydraulic pump that can maintain outputpressure at zero flow for a long periods with no heatbeing generated. air DRIVEN PUMPS will do thisover virtually any pressure range. VALVE ACTUATION:Pipeline gas is commonly used for bootstrap operationof pneumatic valve actuators. But where high forcerequirements meet low gas pressures, the size of thepneumatic actuator needed may be impractical.

7 A gasdriven pump with a small hydraulic actuator canoften solve this at less cost. PORTABLE HYDRAULIC TOOLS:To be easily handled on the job, these tools must becompact with minimum weight. This means hydraulicpressures beyond the reach of rotary hydraulic PUMPS ..but easily provided by air DRIVEN hydraulic portability of the pump-tank package, the oil supplyneed be little more than the displacement of the tool it isteamed with because overheating can not HII pump & tank unitwith optional hand pump kit ifair or gas not availableQUICK REFERENCEINTERNATIONAL EQUIVALENTSPRESSURE:1 BAR = PSI = 100 Kpa = Kg/cm21 Mpa = 10 BAR = 1000 KpaVOLUME:1 LITRE = 61 IN3=.
