Range of pump kits offer performance specifically tuned to needs of solvent delivery, with no random flow variations and highly accurate flow repeatability
FMI pump models QSY-1CSC and QSYX2-1CSC have proven well suited for solvent delivery on preparative chromatographic columns and for new high-performance pre-packed columns for flows up to 1380ml/hr where pressure does not exceed 100psig.
Unlike conventional valved pumps, the valveless FMI LanB pumps do not exhibit random flow deviations.
The unique directly coupled valveless piston design and synchronous motor drive assure long-term drift-free flow and mechanical stroke stability. Solvent compatibility is excellent, because the fluid contacts only chemically inert materials.
Repeat flow setting of 0.1% are attained by the use of the dial indicator kit Q485.
The instant reverse feature without having to change tube connections allows easy and direct column back-flush.
The smooth sinusoidal output (72 pulses/min) is easily damped in critical applications by use of an FMI pulse dampener PD-60-LF.
To facilitate direct connection of 1/4-28 low dead volume fittings, the company has included low flow fitting kit R479.
