Vanton CHEM-GARD® Horizontal Centrifugal Pumps

Horizontal Centrifugal Pumps

– Wet end components of Vanton CHEM-GARD® centrifugal pumps are injection molded
or fabricated of homogenous polypropylene (PP), polyvinyl chloride (PVC), chlorinated
polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF) – corrosion resistant
thermoplastics that are chemically inert to the fluids they are specified to handle. The
heavy-duty stainless-steel shaft is completely isolated from the fluid by a thick-sectioned
thermoplastic sleeve, eliminating metal contact with the pumped fluid.

– Unlike metals (including stainless steel, Hastelloy® and other alloys) that have annual
rates of corrosion, Vanton thermoplastics are inert, allowing ultrapure liquids to be
transferred free of contamination.

– To fit virtually any new or existing application CHEM-GARD® pumps are offered in
numerous configurations including ANSI, DIN, self-priming, close-coupled, mag-drive,
combination close-coupled/mag-drive, seal-less, and motor designs with integral pump

– It means that a Vanton pump can meet and exceed your performance requirements,
while conforming to your new or existing dimensional specifications.

– The wet end is comprised of solid, thick-sectioned, stand-alone components (unlike
plastic linings), that are easily replaced, maximizing uptime while minimizing cost.

– The unique combination of advantages makes CHEM-GARD® pumps ideal for the
transfer of process fluids, treatment chemicals, plant effluents and industrial or municipal
water and waste streams. For transfer of slurries, stringy materials, and liquids
containing solids to 2 in. (51 mm) in diameter, CG, CGA and CGC models of CHEMGARD® pumps are available with Vortex pump heads.

– Every Vanton pump is fully tested to verify performance with all data permanently



Horizontal Centrifugal Thermoplastic Pumps Conforming to ANSI 873.1 Process Pump Standards.

  1. Plastic sleeve isolates the stainless steel shaft from the fluid being pumped.
  2. 0-ring seals between the plastic sleeve and the impeller, and between the impeller and the locknut, assure no metal contact with solution.
  3. The retractable front bearing can be pulled back on parallel bars for easy seal inspection, reduced maintenance and assuring perfect alignment.
  4. Heavy duty, self aligning bearings widely spaced on the shaft, for maximum stability and long seal life.
  5. The relatively short, large diameter stainless steel shaft with generous radii significantly reduces stress concentrations and avoids the potential for shaft failure.
  6. Camlock bearings are utilized to allow easy adjustment of the impeller.
  7. Heavy sectioned static casing 0-ring prevents leaks and blow outs.
  8. Key driven, dynamically balanced molded impeller design with stainless steel imbedded insert ensures positive drive, provides additional rigidity to impeller at higher temperatures and pressures, and prevents damage in case of reverse rotation. Semi­open or closed impellers are available.
  9. Heavy wall, homogeneous molded thermoplastic casing and casing covers.
  10. Quick servicing back pullout construction per ANSI B73.1 and leveling bolt to facilitate removal and reassembly.
  11. Heavy duty epoxy coated metal armor serves to carry nozzle loading.

As standard Vanton procedure, every pump is fully tested to applicable Hydraulic Institute specifications in our plant prior to shipment. Test reports for each pump are kept on file at the company.

* Baseplate dimensions will vary slightly with motor frame size. All dimensions are inches and are approximate and not to be used for construction purposes. Pump dimensions conform to ANSI B73.1. Design specifics subject to modification as dictated by ongoing product improvement programs.
