All Vanton vertical centrifugal sump pumps are specifically designed to handle
corrosive, abrasive and hazardous process fluids, wastewater liquids and
slurries of various pH values, and for use in those applications where no
metallic or other contaminants can be tolerated. The cantilevered
large diameter shaft design of SGK pumps eliminates the necessity
for any immersed bearings and permits dependable operation
under dry running conditions. These pumps are available
in lengths to 4 feet but can accommodate deeper sumps
through the use of tail pipes. Models are available with standard
semi-open or closed impellers, or with recessed impellers that
provide unrestricted flow so that fluids with solids or stringy
materials can be pumped without impeller clogging.
MATERIALS OF CONSTRUCTION
All pump components in contact with the fluid are furnished in a
choice of chemically inert thermoplastics: polyvinyl chloride (PVC),
chlorinated polyvinyl chloride (CPVC), polypropylene (PP) and
polyvinylidene fluoride (PVDF). The heavy duty alloy steel shaft is
completely isolated from the fluid by a heavy sectioned thermoplastic
sleeve. No metal is in contact with the pumped fluid,
APPLICATIONS
Vanton SGK sump pumps are specified where submerged
bearings cannot be tolerated because sudden fluid stoppage will result in
running dry for short or extended periods. If this occurs, no harm will come
to the pump. They are also recommended where regulations prohibit draining
tanks from the bottom. They are
in wide use for the transfer, collec-
tion and circulation of aggressive
or ultrapure fluids in chemical,
petrochemical, environmental,
manufacturing and wastewater
applications where running dry
capabilities are important to mini-
mizing maintenancecosts and
maximizing MTBR.
ADVANTAGES OF THERMOPLASTICS
• Greater chemical resistance over the pH range compared to metals or thermosets.
• Superior resistance to abrasion compared to metals or thermoset composites.
• No metallic contamination of the fluid.
• No problems with galling. Easier maintenance.
• No interbatch product contamination. Fiberglass composites wick and absorb by
capillary action. Solid homogeneous thermoplastics don't.
• No galvanic corrosion or rusting. Metals corrode, plastics don't.
