For Accurate and Dependable Handling of Discrete Fluid Streams in Sanitary Applications

Suffix 'SAN' designates FMI Pump Head Modules design specifically to confirm with the Milk Ordinance and Code recommended by the US.  Public Health Service for equipment employed in sanitary applications.  These pump head modules may be used with any standard pump drive module to provide any desired flow rate range within the scope of the FMI product line.

All fluid contact surfaces in 'SAN' series pump heads are highly resistant to chemical and biological attack and are easily dismantled for scrubbing, sterilizing, brushing or other cleaning procedures.  There are no internal threads or blind holes in 'SAN' pump head components and all pump heads are readily changeable with one another.  Thus, sanitary procedures may be fastidiously followed without loss of system operating efficiency

In 'SAN' pump head modules, sapphire-hard piston and cylinder components, fitted to a clearance of 50 millionths of an inch, promise minimal wear (even in the presence of mild abrasives).  In short 'SAN' pump head modules are the ultimate in sanitation ease, rugged dependability and outstanding accuracy at realistic prices.

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 1380 ml/hr. where pressure does not exceed 100 psig.  Unlike conventional valved pumps, the valveless FMI Lab Pumps do not exhibit random flow deviations.  The unique directly coupled valveless piston design and synchronous motor drive assure longterm drift-free flow and mechanical stroke stability.  Solvent capability 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 P/N Q485.  The instant reverse feature without having to change tube connections, allows easy and direct column backflush.  the smooth sinusoidal output (72 pulses per minute) 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, we have included Low Flow Fitting Kit P/N R479.
