Open the catalog to page 7Pressure Compensator “P-1” Ensures maximum pump flow until unit reaches preset control pressure setting then regulates output flow to match the requirements of the system while maintaining preset output pressure. Pump Controls Can be adjusted from 200 psi (250 psi for PVG150) working pressure up to the maximum pressure rating of pump. Dual Pressure Compensator “P-2” Provides two independently adjustable pressure compensated settings as selected by an integral solenoid.
Open the catalog to page 8Soft Start Pressure Compensator “P-C” Pump starts “softly” by going quickly at low pressure to a reduced flow setting, thereby reducing start up torque requirements. A constant flow output is maintained for a given flow control valve setting regardless of changes in drive speed and/or working pressure. Pump Controls
Open the catalog to page 9Load Sense Plus “P-1/K” Pump Controls A constant flow output is maintained for a given flow control valve setting regardless of changes in drive speed and/or working pressure. The Load Sense Plus control enables the user to externally adjust the minimum pressure setting without affecting the load sense differential. Horsepower Limiter “P-1/H” Automatically reduces delivery, as unit pressure rises, to limit horsepower consumption.
Open the catalog to page 10Horsepower Limiter w/Load Sensing “P-1/G” Load sensing control matches flow and pressure to load demand until (limited) horsepower setting is reached. Control then automatically reduces delivery as system pressure rises. Load sensing control matches flow and pressure to load demand until (limited) horsepower setting is reached. Control then automatically reduces delivery as system pressure rises. The Load Sense Plus control enables the user to externally adjust the minimum pressure setting without affecting the load sense differential. Pump Controls Horsepower Limiter w/Load Sense Plus...
Open the catalog to page 11Dual Pressure Compensator w/Horsepower Limiter "P-2/H" Provides two independently adjustable pressure compensated settings as selected by an integral solenoid. Automatically reduces delivery, as unit pressure rises, to limit horsepower consumption.
Open the catalog to page 12Electronic Displacement Control (EDC) “P-E” Pump displacement is linearly proportional to an electrical input. An increase in coil current will decrease pump displacement. Pressure compensator control overrides the EDC when preset control pressure setting is reached, then regulates output flow to match the requirements of the system while maintaining preset output pressure. Pump displacement is linearly proportional to an electrical input. An increase in coil current will decrease pump displacement. Load sensing control overrides the EDC and a constant flow output is maintained for a given...
