The Agilent G4220-60250 is a genuine Channel A pump drive assembly, officially designated Drive Unit Channel A Pendulum, for Agilent 1290 Infinity high-pressure pumps. The assembly converts the rotary motion of two electric motors into the reciprocating motion required to drive the pump-head pistons and forms a critical mechanical component of the high-pressure pumping system. It is primarily intended as a service replacement for damaged or worn pump drives, and Agilent lists it for G4220A and G4220B pumps.
