7. ssure to Pump Motor Fluid Pressure Pump ratio is an expression of the relationship between the pump motor area and the lower pump end area EXAMPLE When 150 p s i 10 3 bar inlet pressure is supplied to the motor of a 4 1 ratio pump it will develop a maximum of 600 p s i 41 4 bar fluid pressure at no flow as the fluid control is opened the flow rate will increase as the motor cycle rate increases to keep up with the demand ZAWARNING Refer to general information sheet for additional safety precautions and important information NOTICE Thermal expansion can occur when the fluid in the mate rial lines is exposed to elevated temperatures Example Material lines located in a non insulated roof area can warm due to sunlight Install a pressure relief valve in the pumping system Replacement warning label pn 92325 is available upon re quest TROUBLE SHOOTING Pump problems can occur in either the air motor section or the lower pump end section Use these basic guidelines to help deter mine which section is affected Pump will not cycle e Be certain to first check for non pump problems including kinked restrictive or plugged inlet outlet hose or dispensing device Depressurize the pump system and clean out any ob structions in the inlet outlet material lines e Refer to the motor manual for trouble shooting if the pump does not cycle and or air leaks from the air motor e Damaged motor Service the motor Pum
