• Consists of a big-displacement, low-pressure pump and a small-displacement, high-pressure pump • Aluminum housing • Check valve as well as an unloading valve • When working at a pressure lower than the unloading pressure, both big and small pumps output flow • GPM listed reflects maximum combined flow Chief™ Two-Stage Gear Pumps
Gauges and Meters
• When working at a higher pressure, only small pump outputs flow, which highly reduces the power consumption • Oil Temp: 175F • 3000 max PSI high-pressure pump • 900 max PSI low-pressure pump
