1260 SFC Binary Pump 11
Introduction

Instrument and Operation
Principle of Operation
The binary pump is based on a two-channel, dual-piston in-series design
which comprises all essential functions that a solvent delivery system has to
fulfill. Metering of solvent and delivery to the high-pressure side are
performed by two pump assemblies which can generate pressure up to
600 bar.
Each channel comprises a pump assembly including pump drive, pump head,
and outlet valve. The two channels are fed into cross connector which is
connected to a damping unit and a mixer. A pressure sensor monitors the
pump pressure. A purge valve with integrated PTFE frit is fitted to the Pump
Head B outlet for convenient priming of the modifier channel.
For pump specifications, see “Performance Specifications” on page 28.
