Introduction
This technical note describes the pump head maintenance for the following
pumps:
•1290 Infinity Binary Pump G4220A/B
•1290 Infinity Quaternary Pump G4204A
•1290 Infinity II High Speed Pump G7120A
•1290 Infinity II Flexible Pump G7104A
Agilent recommends using refurbished pump heads for maintenance and
repair instead of disassembling pump heads. Such pump heads are available
through Agilent service.
Please carefully follow all instructions step by step and use recommended
tools like the pump head alignment tool and a torque wrench. Any deviation
from these procedures may damage pump heads or may significantly reduce
the life time of the pump heads.
The 1290 Infinity pump service kit (5067-4699) includes all tools required for
the procedures described in the technical note.
