When
space is critical, cost savings important, and dependable
transfer of aggressive or ultrapure fluids a must,
the Vanton series of close-coupled, end suction thermoplastic
centrifugal pumps is ideal. Its small footprint reduces
space requirements by as much as 20%, initial cost
is appreciably lower than conventional foot mounted
centrifugal pumps, and its availability in solid molded
homogeneous polypropylene and polyvinylidene fluoride
assures reliable fluid handling without corrosion
or product contamination. These quality engineered
metal armored, solid (not lined) nonmetallic pumps
incorporate the superior design and manufacturing
innovations of the Vanton CHEM-GARDŽ line in a smaller,
more compact envelope especially significant for OEM
equipment.
Vanton
CGC pumps are available in your choice of tangential
or centerline discharge that allows removal for maintenance
without disturbing existing piping. Both offer easy
seal access configuration. Their innovative construction
includes a pump shaft assembly completely independent
of the motor shaft, minimizing maintenance and extending
motor service life. The pumps are designed to accommodate
standard C-face motors and commercial mechanical seals.
Where product contamination can not be tolerated,
all fluid contact components can be furnished in virgin
natural and unpigmented thermoplastics to assure the
integrity of high purity water, chemicals, pharmaceuticals
and semiconductor fluids.
SPECIFICATIONS
- Pump casing and cover molded from virgin, homogeneous thermoplastic.
- Dynamically balanced, molded homogeneous thermoplastic semi-open or closed vane impeller with imbedded stainless steel insert. Key driven to assure positive drive in either direction.
- Alloy steel, large diameter shaft with wet and completely isolated from fluid contact by a thick sectioned thermoplastic sleeve.
- Pump accommodates standard single and double mechanical seals without modification. Seals are reverse mounted with nonmetallic seal component inboard to avoid any metal-to-fluid contact, making it unnecessary to use expensive high alloy or exotic metals.
- Shaft bearing is lubricated by direct product flush and positioned to minimize shaft deflection and extend service life.
- Metal armor totally encloses thermoplastic casing and flanges to provide nozzle loadings comparable to those of metal pumps.

and specifications subject to change and may vary
slightly with motor manufacturer selected.
50 Hertz performance curves and metric dimensions are available on request.
For higher horsepower and operating speeds consult factory.
Catalog sheets available on other Vanton centrifugal pump models including self-priming designs, vortex heads, magnetic drive and foot mounted pumps.

ADVANTAGES OF THERMOPLASTICS
- No corrosion or rusting. Metals corrode, plastics don't.
- No interbatch product contamination. Fiberglass composites wick and absorb fluids by capillary action. Solid homogeneous thermoplastics don't.
- No danger of metallic contamination.
- No problems with galling. Easier maintenance.
- Superior resistance to abrasion than metals or fiberglass composites.
- Greater chemical resistance over the full pH range than stainless steel or fiberglass composites.
