2 Overview
2.1 Unit Description
The pump is the heart of the Dionex UltiMate 3000 system. The pump performs equally
well as a flexible and reliable module for routine analysis and sophisticated research tasks
in HPLC and UHPLC and can be used in numerous laboratory environments:

The patented isokinetic pre-compression allows a precise and almost pulse-free flow.

The technical specification meets the highest requirements for flow rate reproducibility,
zero pulsation, and operational reliability (

page 187).

All pumps are fitted with floating pistons, allowing compensation for small mechanical
tolerances within the specification and thus enhancing the robustness of the pump.

As a standard, all pumps are equipped with an active rear seal wash system (

page 21).

Various monitoring and diagnostic features are provided for optimum system
performance and reliability (

page 26).

The pump is designed for easy access to the fluid components, allowing fast and reliable
maintenance while the instrument remains in the UltiMate 3000 system stack.

For the secure and functional positioning of the solvent reservoirs on top of the pump, the
Solvent Racks of the UltiMate 3000 series are available from Dionex (

page 13).
Except for the SR-3000, all Solvent Racks include an integrated vacuum degasser.

The pump can be fully controlled by the Chromeleon Chromatography Management
System, providing a high degree of system integration.

All parts that may be exposed to solvents are made of materials that provide optimum
resistance to the most commonly used solvents and buffer solutions.
