Vanton Chem-Gard® polypropylene

centrifugal pump recirculates corrosive

liquids involved with the scrubbing of

fumes from alkaline cleaners and the

hydrochloric acid pickle.

These Vanton Sump-Gard® polypropylene

sump pumps handle acidic plating

Worthington Steel occupies a unique niche between the integrated mills

that concentrate on large-volume, standard product orders and the

metal service centers that generally have limited processing capabilities.

Worthington has made significant capital investment in its

steel-processing equipment, with the emphasis on maintaining quality

while reducing production and maintenance costs.


Most of Worthington's customized-steel processing operations involve

the cleaning, pickling, and plating of steel strip.


Polypropylene pumps are used because of their ability to resist the acids

and caustic chemicals required for surface preparation and finishing of

the rolled steel strip.


Inert thermoplastic can be applied safely over a broad pH range,

handling acids and alkalies at temperatures from -30° F to 185° F.

Worthington employs the Vanton Sump-Gard® Model SG-PY2400

vertical centrifugal pump with all wetted parts of polypropylene,

including a thick sectioned sleeve over the full length of the steel shaft.

The undersides of the steel cover plates, which support the bracket and

motor of the sump pumps handling the acidic plating solutions, are

laminated with polypropylene to preclude any metallic corrosion or



The initial group of four polypropylene sump pumps was installed in

1984. According to Worthington's plant engineer, the pumps are still

operating without trouble, requiring only routine maintenance and not

causing shutdowns for repairs. These 6-in. x 4-in. thermoplastic pumps

operate at 1.175 rpm and deliver 300 gpm at 42 TDH.


Caustic rinse waters are handled by a Vanton Model PY1800

polypropylene sump pump that moves the alkaline fluid at 150 gpm

against a 70-ft. head.


As part of the efficient scrubbing system designed to collect fumes from

both the alkaline cleaners and the hydrochloric acid pickle, Worthington

depends upon a Vanton Chem-Gard® polypropylene centrifugal pump

with a double mechanical seal. This pump recirculates the corrosive

streams at 170 gpm against a 45-ft. head.


The pump's unique open seal area and retractable front bearing

minimize maintenance and extend seal life. No metal is ever in contact

with the corrosive fluid, but the pump is completely armored in metal to

protect against accidental damage from material-handling equipment.

Plant officials believe that polypropylene pumps have Ied to higher

productivity and lower maintenance costs.

About Us

In the 1950, Vanton developed a revolutionary all-plastic pump for use in conjunction with the first heart-lung device. The design limited fluid contact to only two non-metallic parts: a plastic body block and a flexible liner. This was the birth of our Flex-I-Liner rotary pump. Its self-priming sealless design made it an industry standard for the handling of corrosive, abrasive and viscous fluids as well as those that must be transferred without contaminating the product. Vanton now offers the most comprehensive line of thermoplastic pumps in the industry.
