Thermoplastic Centrifugal Pumps

Thermoplastic, Centrifugal Pumps, Vanton, CHEM-GARD CGCHEM-GARD® CG Thermoplastic Centrifugal Pumps

Vanton CHEM-GARD® thermoplastic heavy duty pumps are designed and constructed to maximize the unique properties of solid homogenous chemically inert thermoplastics. They are not plastic lined metal pumps nor metal pump designs made with plastic components.  They have been engineered to efficiently and reliably transfer corrosive, abrasive and other aggressive fluids, as well as deionized and ultrapure water, pharmaceuticals, reagent grade chemicals and similar liquids which must remain free from metallic contamination. To assure no metal-to-fluid contact, shafting is sleeved in thermoplastics and mechanical seals are reverse mounted.

  1. Pump Casing and Cover: Molded from virgin, homogeneous thermoplastics.

  2. Impeller: Dynamically balanced, molded from virgin, homogeneous material, with an imbedded, stainless steel insert. Key driven to assure positive drive.

  3. Drive Pedestal With Retractable Front Bearing: Designed to provide a wide open seal area. This simplifies inspection, assures minimum shaft overhang and deflection, and reduces maintenance.

  4. Shaft: Stainless steel large diameter shaft with wetted end completely sleeved with thermoplastic to isolate it from the fluid.

  5. Mechanical Seals: The pumps are designed to permit the use of all standard single and double mechanical seals without pump modification. The seals are reverse mounted with the nonmetallic seal component inboard to avoid any metal-to-fluid contact and to make it unnecessary to utilize high alloy or exotic metal seal components.

  6. External Cast Iron Armor: Completely painted with 2-part epoxy chemically resistant coatings for protection against atmospheric corrosion.
