Enerpac PATG-1105N 4.2 Liter Turbo II Air Hydraulic Pump with 3 Way Treadle


  • Air pump for lifting, bolting, or applying pressure with a hydraulic cylinder (sold separately) in settings where compressed air is available or ignition sources are prohibited
  • Advances and retracts a single-acting cylinder or powers a hydraulic tool, and can hold a load
  • Three-position treadle for operation by foot or hand
  • Two-speed pump requires fewer cycles to move a load than a similarly rated single-speed pump, increasing productivity
  • First-stage pressure rating of 100 psi and second-stage pressure rating of 10,000 psi


The Enerpac PATG-1105N Turbo II two-speed hydraulic air pump is for lifting, bolting, or applying pressure with a hydraulic cylinder (sold separately) in plant maintenance, fabrication, production, bolting, vehicle repair, and other applications where compressed air is the preferred power source. It has a three-way control valve for advancing, releasing, or holding a single-acting cylinder. It has an inlet air-pressure range of 25 to 125 psi and can start at low pressure. This two-speed pump requires fewer cycles to move a load than a similarly rated single-speed pump, increasing productivity. The pump is controlled by a treadle that can be operated by hand or by foot. An internal pressure relief valve helps protect the pump from overload. The cast aluminum air motor resists corrosion and wear, and the motor and one-piece piston are designed to minimize air consumption. The motor assembly is fully serviceable, and the reinforced reservoir can withstand harsh conditions. The pump has a return-to-tank port for remote valve applications. The pump has 3/8″ and 1/4″ National Pipe Taper (NPT) threads ports for connecting to an air supply or attaching a hose or gauge (sold separately).


Maximum operating pressure 10,000 pounds per square inch (psi) Maximum output flow rate per minute, at 100 psi 60 cubic in. Maximum output flow rate per minute, at 10,000 psi 10 cubic in. Usable oil capacity 230 cubic in. Inlet air-pressure range 25 to 125 psi Air consumption, at 100 psi 12 standard cubic feet per minute (scfm) Hydraulic air ratio 100:1 Maximum operating noise level 76 decibels (dBA) Weight 22 lb. Dimensions 8.22 x 7.92 x 17.20 inches (H x W x D)

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from back to front.

Hydraulic pumps lift, bolt, or apply pressure to objects by pressurizing and moving hydraulic fluid. A hydraulic pump consists of a base, a reservoir that holds hydraulic fluid, and an operating mechanism, such as a handle or foot pedal, an electric motor, compressed air, or a gasoline engine. When the operating mechanism is activated, pressurized hydraulic fluid from the reservoir is delivered through an attached hose to a hydraulic cylinder. The pressurized hydraulic fluid in the cylinder lifts the cylinder’s piston, which in turn lifts the load. Hydraulic hand pumps are usually made of steel, or aluminum and nylon, and can be single-speed or two-speed. They are used in a wide range of applications, such as construction, manufacturing, and maintenance and repair applications in both industrial and home settings.

Enerpac manufactures industrial hydraulic equipment for lifting, workholding, and other applications, and provides integrated lifting solutions for bridge construction, mining, shipbuilding, and other industries. The company, founded in 1959, is headquartered in Menominee Falls, WI.
