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.

CAUTION
Damage of the pump piston
Removing pump heads in a position other than the maintenance position can damage
the pump piston.
➔Before switching off the pump, bring it to the maintenance position.
CAUTION
Damage of pump drives
The pump drive can be damaged if the pump initializes after switching it on without
having the pump head installed properly.
➔Use the Lab Advisor maintenance procedure for replacing pump heads.
➔Install the pump head correctly before switching on the pump.
NOTE
This procedure shows how to remove a pump head assembly from an Infinity I Binary
Pump module (G4220A/B).
Removing pump head assemblies from an Infinity II High Speed Pump (G7120A) will be
done in the same way.
NOTE
This procedure describes how to remove the pump head assembly of channel A. The same
steps apply for channel B.
The primary pump head does not have a heat exchanger. Seal wash parts are optional for
both pump heads (G4220A/B only).

Pump Head Maintenance (Binary and High Speed Pumps) 2
Disassembling the Pump Head
1In Lab Advisor go to Service & Diagnostics >
Remove/Install Pump Head and follow instructions
given on the screen.
2Close the shut-off valve of the respective pump channel.

2Pump Head Maintenance (Binary and High Speed Pumps)
Disassembling the Pump Head
3Remove the flow connection between the degassing unit
and the primary pump head inlet. Remove the capillary
connection at the top of the secondary pump head to the
pump valve. If installed, remove the tubings of the seal
wash option.
DO NOT REMOVE the capillary connection between the
pump heads marked by the red X.
4Open the 4 screws holding the pump heads.
NOTE
Open all screws step by step, not screw by screw.

15
Pump Head Maintenance (Binary and High Speed Pumps) 2
Disassembling the Pump Head
5Remove the complete pump head assembly by holding it
with both hands and pulling it to the front.
6Open the 2.5 mm hex screw at the top of the primary
pump head, which fixes the connection capillary of the
heat exchanger. Then lift up the capillary and remove it
from the primary pump head.
7Remove both pump heads from the link plate by pushing
the clips at the rear of the plate.
