Description
Overview:
The Pump Half Coupling is a genuine Atlas Copco component designed for LP 9-20 series hydraulic power packs, including LP9-20E and LP9-20El. It connects the hydraulic pump to the drive side of the power pack to transfer torque efficiently and reliably. Built from durable machined metal, it is suited to demanding site use and daily operation. As a direct replacement for OEM number 3377 0051 70, it restores correct drive alignment and helps prevent vibration and premature wear in the pump and motor. This half coupling mates with the corresponding coupling half and centre insert (supplied separately) to complete the assembly, ensuring smooth, consistent power transmission in compact, portable hydraulic power packs used for breakers, saws, and other tools.
