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.

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.
