Milwaukee Tool 3120-21 M18 Hydraulic Pump 10000 Psi

Product Description

The MILWAUKEE TOOL 3120-21 is an M18 brushless single acting hydraulic pump built for demanding trade applications requiring up to 10,000 psi of hydraulic output. Powered by an M18 REDLITHIUM XC5.0 battery pack, this cordless pump delivers consistent pressure without the need for a gas engine or AC power source. The usable oil capacity of 0.25 gallons provides 60 cubic inches of flow, sufficient to fully extend a wide variety of small single acting cylinders and tools to full stroke. At 18.6 pounds, it is engineered to be compact and portable for jobsite use. Licensed electricians, ironworkers, and industrial maintenance technicians are the primary installers and operators of this equipment.

This pump is designed for use with single acting hydraulic cylinders, rams, and crimping or cutting tools rated at 10,000 psi. It is well-suited for electrical utility work, structural steel erection, mechanical maintenance, and similar industrial trade applications where a portable, battery-powered hydraulic power source is required. The two-position manual valve and trigger lockout allow controlled operation in the field. The included shoulder strap supports hands-free transport between work areas on the jobsite.
