The MLSM Series Live Pak pump system provides protection against hydraulic overspeed damage while allowing the driver to maintain full use of the hydraulic system on refuse vehicles. The built-in flow limiter automatically redirects excess pump flow to reservoir when the pump is on. In the off mode full pump flow is directed to the reservoir at an extremely low return pressure to conserve fuel by minimizing horsepower draw. The Live Pak system works without hydraulic or electronic overspeed controls, governors, or dry valves.
