Milwaukee 3120-21 M18 Brushless Single Acting 60 in 3 10,000psi Hydraulic Pump - 754143
The MILWAUKEE M18 Brushless Single Acting 60in3 10,000psi Hydraulic Pump eliminates manual pumping, delivering up to 2.5X faster application speeds. By eliminating the need to manually pump, this solution vastly reduces fatigue, with up to 95% less muscle effort vs. hand pumps, delivering increased productivity and faster applications. The single-acting pump features 60in3 of usable oil to fully extend a wide variety of small tools and cylinders to full stroke. The single-acting hydraulic pump is designed to be fully compatible with all existing 10,000psi single-acting rated hydraulic hoses and cylinders. A manual valve allows precise control over return flow, while a bladder window allows you to quickly gauge fluid levels. At 12.6lbs, this compact pump is highly portable and allows easy transport to your application. A trigger lock-out helps prevent unwanted tool activation in transport, set up, and tear down. The kit includes (1) M18 XC 5.0 REDLITHIUM Battery, an M18 and M12 Multi-Voltage Charger, a Shoulder Strap, and a 3/8" NPTF Female Quick Connect Cone Poppet Coupler (installed on the tool).
