  • When and How to Adjust a Load-sensing Hydraulic Pump

    Adjusting Pressure- compensating Pumps. Adjusting a pressure-compensating pump is quite simple. With all flow blocked and the system idle, the compensator valve is adjusted to the desired pressure. However, some pressure-compensating pumps have two valves mounted on the pump body. The two adjustments can look nearly identical.
