Overview of the Hydraulic Path

The Low Pressure Mixing Pumps are 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 one pump assembly which can generate pressure up to
600 bar.
In the quaternary pumps, degassing of the solvents is done in a built-in vacuum
degasser. Solvent compositions are generated on the low-pressure side by an
MCGV.
The pump assembly includes a pump head with an inlet valve and an outlet valve.
A damping unit is connected between the two piston chambers. A purge valve
including a PTFE frit is fitted at the pump outlet for convenient priming of the
pump head.
