The Type V40M-028H axial piston pump is suitable for hydraulic fan controls in mobile machines. The pump will displace volumes up to 28 cm3/rev and is designed for maximum operating pressure of 380 bar and peak loads of 400 bar. The optional P1R1 electronic pressure controller continually adjusts the pump so the fan’s cooling output is fine-tuned to the temperature of the machine’s engine, increasing pressure in the event of a power failure and protecting the engine against overheating.
