CHEM-GARD® CGMC Thermoplastic Close-Coupled,
Magnetically Driven, Sealless Centrifugal Pumps

• Polypropylene (PP) or
Polyvinylidene Fluoride (PVDF)
Construction
• Flows to 400 gpm (91 m3/hr)
• Heads to 180 ft (55 m)
• Temperatures to 225°F (107°C)
Corrosion-free and contamination-free
handling of acids, caustics and ultra-pure
liquids with zero emissions in a compact size
Vanton Chem-Gard® CGMC
magnetically driven end suction
process pumps are sealless,
single stage, close-coupled
centrifugal pumps. All fluid
contact parts are injection
molded of solid, stand-alone
polypropylene (PP) or
polyvinylidene fluoride (PVDF).
CGMC pumps eliminate
corrosion associated with metal
pumps, wicking and
contamination associated with
fiberglass pumps, and porosity/
delamination associated with
lined metal pumps.
With no mechanical seals
to leak or emit vapors, these
sealless pumps offer zero
emission performance, making
them the environmentally safe
choice for transferring acidic,
caustic, volatile and otherwise
hazardous fluids.
High performance permanent
rare earth magnets transmit
power, with the inner magnet
rotor assembly encapsulated
in thick-walled PP or PVDF. A

non-metallic containment can
assembly reduces losses in
pump efficiency by eliminating
troublesome eddy currents.
Rugged thermoplastic wet end
components are encased by
structural metal armor allowing
CGMC pumps to withstand
the same nozzle loadings as
metal pumps.
Equipped with NEMA or
metric C-face motors, the
close-coupled CGMC design
eliminates the cost and concern
associated with pump/motor
alignment, while reducing
overall length by approximately
20 percent compared to
conventionally mounted
pumps, allowing placement
in restricted spaces. The
CGMC hydraulic head conforms
to ANSI B73.1 process pump
dimensional standards,
allowing drop-in replacements
without piping or installation
modifications.

Advantages of solid thermoplastics
•

Chemically inert, eliminating corrosion unlike metal pumps,
all of which have annual corrosion rates.

•

Eliminates product contamination. Fiberglass composites wick,
absorbing fluids by capillary action. Solid, homogeneous PP
and PVDF do not.

•

Zero ionization or metallic contamination, ensuring product
integrity.

•

No galling problems associated with metal wet ends.

•

No delamination or porosity associated with lined
metal pumps.

•

Greater chemical resistance across the entire pH range than
metal alloys.

Compact footprint up to 20% shorter
than standard foot-mounted designs
