Design and function
The Atlas Copco LP 9-20 P is a hydraulic power
pack designed for operating Atlas Copco hydraulic
breakers and other work tools. The power pack is
fitted with a 9 HP Honda GX 270 air cooled petrol
engine with hydraulic POD system (power on
demand). The oil flow of the LP 9-20 P power pack
is 20 l.p.m. (5 US gal/min).
Note! The torque of the engine is reduced
when reducing the rpm. The power pack
can therefore not in all cases deliver the
maximum pressure at low rpm.
