Milwaukee M18 Brushless Single Acting 60 In³ 10,000 PSI Hydraulic Pump Kit
Product Overview
The Milwaukee M18 Brushless Single Acting 60 In³ 10,000 PSI Hydraulic Pump Kit (3120-21) provides cordless hydraulic power for professional applications that use 10,000 PSI single-acting hydraulic equipment. It replaces manual pumping with an M18-powered brushless motor, helping users complete hydraulic applications faster while significantly reducing the physical effort required.
The pump provides 60 in³ of usable hydraulic oil, allowing it to fully extend a wide range of smaller single-acting cylinders and hydraulic tools to full stroke. A manual valve gives the operator precise control over return flow, while the built-in bladder window makes it easier to monitor fluid level.
At approximately 12.6 lb with the included M18 XC5.0 battery, the pump is designed for portability and can be carried using the included shoulder strap. The kit also includes an M18/M12 charger and a 3/8-inch NPTF female quick-connect cone poppet coupler installed on the pump.
Key Features
10,000 PSI maximum hydraulic pressure for compatible high-pressure single-acting applications.
60 in³ usable oil capacity supports full-stroke operation of a wide variety of smaller cylinders and tools.
Brushless motor provides cordless hydraulic power with improved durability.
Up to 2.5X faster application speeds compared with manual pumping, according to Milwaukee.
Up to 95% less muscle effort than hand pumps, helping reduce operator fatigue.
Manual return-flow valve provides controlled and precise hydraulic release.
Bladder-level viewing window allows quick inspection of the hydraulic fluid level.
Trigger lockout helps prevent unintended activation during transportation, setup, and teardown.
Integrated D-rings provide tie-off points when working at height.
Shoulder strap included for easier carrying and positioning.
3/8-inch NPTF female quick-connect coupler is installed on the pump and works with common cone-poppet and ball-poppet male couplers.
M18 cordless platform allows the pump to operate with Milwaukee M18 batteries and chargers.

What's Included
The 3120-21 kit contains:
1 × M18 Brushless Single-Acting Hydraulic Pump, 3120-20
1 × M18 REDLITHIUM XC5.0 Battery Pack, 48-11-1850
1 × M18 & M12 Multi-Voltage Charger
1 × Shoulder Strap
1 × 3/8 in. NPTF Female Quick-Connect Cone Poppet Coupler, installed on the pump
Hydraulic Compatibility
The pump is intended for use with 10,000 PSI-rated single-acting hydraulic hoses, cylinders, and tools. Its quick-connect configuration is compatible with common cone-poppet and ball-poppet male couplers, making it suitable for a range of existing hydraulic equipment when the complete system is properly rated.
The 60 in³ usable oil capacity is particularly useful for smaller hydraulic cylinders and tools that require enough fluid volume to reach full extension. It is not a general-purpose fluid-transfer pump or a high-flow hydraulic power unit for applications requiring substantially greater flow or different pressure ratings.
Portable Cordless Design
Unlike conventional manually operated hydraulic pumps, the 3120-21 uses an 18V M18 battery-powered brushless motor to generate hydraulic pressure. This eliminates the repeated manual pumping motion and makes the pump easier to position at the point of use.
The compact housing measures approximately 18 inches deep, 5.4 inches wide, and 9.5 inches high, while the complete unit weighs about 12.6 lb with the included XC5.0 battery. The shoulder strap and integrated D-rings provide additional carrying and positioning options.
Ease of Operation
The pump incorporates several features intended to simplify hydraulic work:
Manual Return Valve
The manual valve allows the operator to control hydraulic return flow rather than relying solely on an automatic release.
Fluid-Level Window
The bladder window provides a quick visual method for checking the hydraulic fluid level.
Trigger Lockout
The lockout helps prevent accidental activation while the pump is being transported, positioned, connected, or removed.
Quick-Connect Coupler
The supplied 3/8-inch NPTF female cone-poppet coupler is already installed, reducing initial setup work.
Ideal Applications
The Milwaukee 3120-21 is well suited for professional applications involving compatible 10,000 PSI single-acting hydraulic equipment, including:
Hydraulic cylinder operation
Portable hydraulic tooling
Maintenance and repair work
Equipment servicing
Mechanical and industrial applications
Lifting and positioning applications using compatible cylinders
Hydraulic tools requiring a 10,000 PSI single-acting power source
The exact application must always be matched to the pressure, oil-volume, hose, coupler, and cylinder requirements of the hydraulic system.
Why Choose the Milwaukee 3120-21?
The Milwaukee M18 Brushless Single-Acting 60 In³ 10,000 PSI Hydraulic Pump Kit combines high-pressure hydraulic capability with the portability of Milwaukee's M18 cordless platform. Its 10,000 PSI rating, 60 in³ usable oil capacity, brushless motor, manual return valve, fluid-level window, and compact design make it a practical alternative to manually operated hydraulic pumps for compatible single-acting equipment.
The complete kit also includes an M18 XC5.0 battery, charger, shoulder strap, and installed quick-connect coupler, allowing users to start with a complete cordless setup rather than purchasing the primary power components separately.
Important Compatibility Note
The 3120-21 is specifically a single-acting 10,000 PSI hydraulic pump. Before connecting it to existing equipment, verify that the hose, cylinder, hydraulic tool, couplers, and other components are all rated for 10,000 PSI and are compatible with the pump's single-acting configuration. The pump should not be selected solely based on pressure rating; required oil volume and hydraulic flow requirements must also match the application.
