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.
