Thermoplastic Centrifugal Pumps      
 More Information

Vanton manufactures heavy duty horizontal centrifugal pumps with designs that took advantage of the superior chemical inertness, abrasion resistance, low weight and precision moldability of plastics. The Vanton line of Chem-Gard® centrifugal pumps delivers flows up to 1450 GPM at discharge heads to 280 feet and temperatures to 275°F. The unique power frame provides a wide open seal area and retractable bearing for ease of maintenance and unlimited choice of mechanical seals.
These pumps are available to ANSI B73.1 process industry standards, as well as to ISO/DIN standards.With the experience gained from horizontal centrifugals, we subsequently developed a dependable line of vertical thermoplastic pumps, having the same flow characteristics as the horizontals. These Sump-Gard® pumps are available for depths to 20 feet. A complementary series of "bearingless" cantilever pumps was designed, resulting in the most complete line of thermoplastic vertical pumps in the industry.

Vanton designers are dedicated to matching pumping needs with new developments in thermoplastics. It’s no wonder that the prestigious members of the Chemical Engineering product Research Panel named Vanton their first choice in thermoplastic pumps by a 5 to 1 margin over our closest competitor. When performance, design, experience and personalized service are critical, there is no "or equal" to a Vanton...the pump professionals prefer.

CHEM-GARD® CGA thermoplastic end suction centrifugal pumps meeting ANSI B73.1 process pump standards. Also available to ISO/DIN standards. They incorporate the highly desirable design features of the time-proven Vanton CHEM-GARD line and are completely interchangeable with all ANSI centrifugal without disturbing piping, baseplate, foundation, driver or coupling. CGA/ANSI pumps are available in PP, PVC AND PVDF for flow rates to 1,450 GPM, heads to 400 ft. and temperatures to 275° F. (For CGM-magnetic drive thermoplastic pumps, request catalog 11.04).
Thermoplastic Vertical Centrifugal Pumps
SUMP-GARD® heavy-duty engineered vertical centrifugal sump pumps in capacities to 1,450 GPM, for temperatures to 275° F, heads to 210 ft. and depths to 20 ft. Available in PP, PVC, CPVC and PVDF in standard as well as "bearingless" cantilevered designs. Unique vapor seal protects external bearings and motor from corrosive fumes. No metal components in contact with fluid.
Flex-I-Liner pumps are sealless and self-priming. They can pump in either direction and can run dry. Flex-I-Liner pumps can be furnished with electric motors, with rotary vane air motors or with variable speed drives for metering purposes.

Providing a gentle, pumping action that eliminates churning or foaming, the pump moves fluid without having it come in contact with any metallic parts. The pump’s operation is based on the fluid traveling between the interior wall of a rugged themoplastic body block and the outer wall of a flexible, elastomeric liner. A rotor mounted on an eccentric shaft rotates within the flexible liner creating a squeegee action on the fluid, thereby forcing it in the desired direction.
Flex-I-Liner pumps are sealless and self-priming
Non-Metallic Tank Pump Systems   More Information
TANK/PUMP SYSTEMS for corrosive, abrasive and ultrapure liquids, constructed with all fluid contact surfaces of chemically inert engineered plastics. Rectangular and cylindrical designs in capacities from 50 to 2,500 gallons are furnished with all necessary pumps, valves, piping, instruments and controls. Standard tanks are furnished in a variety of non-metallic materials, but for pressurized service they are also available in carbon or stainless steel with appropriate thermoplastic linings.
SGL-Giraffe   More Information  
The Vanton SGL-Giraffe® pump is 29 feet tall. Its new, unique design now makes it economically feasible to build all-plastic, vertical, centrifugal pumps for sumps up to 50 feet deep. Since no metal ever contacts the fluid being pumped, it is ideal for handling a wide variety of corrosive and abrasive liquids and slurries.

These new Vanton pumps feature modular, segmented shaft and column construction which substantially reduces shipping, installation and maintenance costs. Available in PVC, CPVC, PP and PVDF, with semi-open, closed or "Vortex" recessed impellers, they are rated for flows to 1450 GPM, heads to 280 feet and temperatures to 275° F.
