Maintenance
Kits and Service Options
Service of the IDP-7 should be performed by properly
trained personnel only.
Agilent pumps will provide many years of trouble-free
service if the maintenance procedures and intervals are
observed. Cleaning and tip seal replacement are recom-
mended when pump base pressure has risen to an unac-
ceptably high level for your application. If your pump
exhibits humming or grinding noises from the bearings, a
major overhaul should be done by Agilent or an autho-
rized rebuild center. Advance exchange pumps are avail-
able to minimize downtime.
The parts needed for tip seal replacement on the IDP-7
are available in the kit described in Table 5. This kit con-
tains seals and O-rings, and can be obtained from your
Agilent dealer.
Service
Agilent offers rebuilding service at our repair centers, or
you can obtain advance exchange of complete IDP-7
pumps. The service plans available and their ordering
numbers are given in Table 6.
Cleaning
Exterior
The exterior surfaces of the IDP-7 may be cleaned with a
cloth slightly moistened with water. If necessary alcohol
or a mild detergent may be used instead. Do not pour or
spray any liquids onto the pump.

two to flush it out. For more information, see “Cleaning
