Control Options

Pressure Limiter Control (C): Limits maximum system pressure with an adjustment range of 26-280 bar. The pump achieves full displacement unless restricted by system valves or maximum pressure is reached.
Load Sensing and Pressure Limiter (L): Matches pump flow and pressure to system demands, reducing horsepower losses. It features a differential adjustment range of 10-40 bar.
Remote Operated Pressure Limiter (AM): Allows remote adjustment of the pressure compensator setting via a relief valve connected to the control.
Torque Limiting Controls (AMT, ANT, L0T): Combine pressure limiting with torque limiting to manage input torque under varying power demands.
Electronic Proportional Pressure Limiting (AE, AF): Integrates a proportional relief valve for electronic adjustment of pressure settings, with options for 12VDC and 24VDC solenoids.
Electronic Unload/Cold Start (C03, C06, L03, L06): Features an unload function to reduce torque during cold starts by de-stroking the pump.
Electronic Proportional Displacement & Pressure Limiting (P, T, S, U): Uses electronic proportional valves to control displacement and pressure, with options for minimum or maximum displacement defaults.

Performance Characteristics
