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.
