• 8.1 cu. in oil volume per stroke
• 5000 psi maximum operating pressure
• 400 psi minimum operating pressure
• 2: 1 pressure ratio
• Mechanical energy transfer system

The Enerpac B81 is a receiver booster that is operated by an external cylinder controlled by a mechanical energy transfer system. It has an 8.1 cu. in. oil volume per stroke. This booster can be mounted in either a horizontal or vertical position for flexible fixture design. Its closed design prevents machining chips and coolant from entering the hydraulic circuit. The N no-leak palletized system eliminates oil loss at the connection point.

Hydraulic system schematics:

The Activator Wand RA1061 is placed into the receiver booster B81 or B171. The mechanical transfer of force from the activator wand plunger to the booster piston provides oil flow to the system.
