3. For example a 3 1 ratio oil pump 3 1 ratio x 100 psi air 300 psi fluid outlet A 3 1 pump is capable of 5 1 on the downstroke and will develop 5 1 pressures under normal operation A grease pump has a ratio of 50 1 However it is capable of reaching a stall pressure equal to 60 times the air input pressure To calculate the fluid output pressure using the air regulator reading multiply the regulator gauge by 60 For example 140 psi air x 60 8400 psi fluid output 0 97 MPa air x 60 58 2 MPa 99 7 bar x 60 582 bar Regulate air to the pump so that no air line or fluid line component or accessory is over pressurized Priming the pump 1 Close the air regulators and bleed type master air valves to all but one pump 2 Open the master air valve from the compressor 3 For the pump that is connected trigger the dispens ing valve into a grounded metal waste container making firm metal to metal contact between the container and the valve 4 Slowly open the bleed type master air valve and open the pump air regulator just until the pump is running When the pump is primed and all air has been pushed out of the lines release the trigger 5 If you have more than one pump repeat this pro cess for each pump in your system NOTE When the pump is primed and has sufficient air Supplied to it it starts when the dispensing valve is open and shuts off when closed 11 Operation Step 6 is for Oil Pumps Only
4. T 4 FIG 4 a Pump cylinder relief passage b Inlet check relief passage Thermal Relief Theory of Operation The pump operation is similar to most double acting reciprocating pumps The pump only comes to a com plete stop on the up stroke The pump will stroke through on the down stroke due to the inlet check relief passage Excess pressure due to downstream thermal expansion causes the air motor pump to run backwards down ward Fluid pressure is relieved through the inlet check relief passage as the pump piston moves downward Air pressure is simultaneously relieved through the air inlet passage The pump piston moves downward exposing the pump cylinder relief passage at the bottom of the stroke Additional excess pressure is then relieved through both the inlet check relief passage and the pump cylinder relief passage Pressure is relieved at the pump through the pump inlet relief passage The pump will not change over on the bottom of the stroke as a result of relieving excess pres sure due to the positioning of the pump cylinder groove with respect to the air motor pilot valve NOTE e The air supply does not have to be turned off to enable thermal relief activation e The Thermal Induced Pressure Relief design fea ture of the pump will cause the pump to dive on the downstroke when a dispensing valve is closed 3A1334E Install only one pump per delivery system Do not use the pumps in a parallel pump install

25. ssure Relief Oil pumps only THERMAL EXPANSION HAZARD Fluids subjected to heat in confined spaces including hoses can create a rise in pressure due to the thermal expansion Over pressurization can result in equipment rupture and serious injury Oil pumps have a built in thermal induced pressure relief as shown in FIG 4 To ensure system pressure will automatically bleed excess thermal induced system pressure through the pump and back to the oil reservoir Always use a relieving air pressure regulator to allow the pump motor to run backwards The regu lator bleeds excess air pressure There should not be any obstructions between air inlet of pump and regulator There should not be any obstructions between the downstream plumbing and pump outlet such as closed ball valves or check valves There should not be any obstructions between the pump inlet and fluid container such as closed ball valves or check valves Only use Graco designed suction tubes for in drum or in tank applications Only use Graco designed suction tubes with a built in relief device for wall mount applications Always use an inlet screen to prevent debris from plugging relief passages from entering the pump Do not operate the pump with out an inlet screen Periodically inspect the inlet screen for plugging Graco recommends inspecting the inlet screen every time the container is changed out 10 es R LE L L A
