Standard pallet assembly components are the
specified FRP material with Alloy C276 stem (if the
pressure or vacuum setting is above the minimum
setting). The pallet, retainer plate and diaphragm
are attached to the stem with a flat washer, lock
washer and hex nut which are generally noted as
items 12, 13 & 14 for each available model. If the pressure or vacuum setting is lower than what
can be attained with the standard FRP/Alloy C276
pallet assembly, an all PVDF assembly is available.
The pallet, retainer plate and diaphragm are
attached to the stem using double Fluoropolymer
hex nuts (Item 21). The all PVDF assembly is
available for both pressure and vaccum ports for all
models and sizes.
The drawings of all six models follow in Figures 8 – 13. Representative Bill of Materials are
structured as follows for each model.
 Column 1: Epoxy Vinyl Ester Presin 411-45 FRP with Alloy C276 internal metal components.
 Column 2: Epoxy Vinyl Ester Presin 411-45 FRP with PVDF pallet assemblies.
 Column 3: Epoxy Vinyl Ester Presin 470-36 FRP with Alloy C276 internal metal components.
 Column 4: Furan FRP with Alloy C276 internal metal components.
Note that the PVDF pallet assemblies can be used with any FRP material.
