Performance Curve

Flow Modifier Designs
FML (shown above)-Designed with a large gland bolt and gasket circle, the FML is preferred for most applications:
Single internal cartridge seals
Dual internalexternal cartridge seals
Single internal component seals with flexibly mounted seats
Dual internal"true" tandem design cartridge seals

Cylindrical Bore Designs
CBL (shown above)-With an oversized cylindrical step bore, the CBl is ideal for seals with large gland bolt and gasket circles. It may be used with:
Dual internal component seals that isolate the seal chamber from the process with external barrier fluid
Single seal with throttle bushing and flush to boost pressure over flash point

FMS- Similar to the FMl the fms accommodates seals with small gland bolt and gasket circles. It is ideal for all mounting configurations of single seals

CBS- The CBS is designed for packing arrangements and conventional seals with small gland bolt and gasket circles.

FMI-The FMI incorporates a cast-in integral gland. It utilizes the shaft sleeve for seal setting and fast instal-lation. It may be used with Single internal, flexibly mounted seals Sanitary-type applications
