chem-gard cga Horizontal Centrifugal Pumps Overview > CHEM-GARD® CGA


Thermoplastic Horizontal Centrifugal Pumps meet ANSI B73.1 standards

  • Flows to 1150 gpm (261 m3/h)
  • Heads to 185 ft (56 m)
  • Temps to 275°F (135°C)
  • Construction: PP, PVDF
CHEM-GARD® CGA thermoplastic pumps with end suction, centerline discharge and back pullout construction, combine the award winning wide-open power frame of Vanton's CHEM-GARD® line of thermoplastic pumps with the standard dimensional characteristics embodied in ANSI specification B73.1. They are fully interchangeable with all other pumps manufactured to this specification without disturbing piping, base plate, foundation, driver or coupling. At the same time, they incorporate thermoplastic construction that will eliminate chemical attack and minimize abrasive wear.

Vanton injection molds all fluid contact components from a range of homogeneous thermoplastics, ensuring that the wet end of each pump is chemically inert to the fluids — and resistant to the abrasives — it may encounter. These thermoplastics include: polypropylene (PP) and polyvinylidene fluoride (PVDF).

The thermoplastic pump casing and flanges are protected by metal armor in order to withstand the same nozzle loadings as metal pumps, while limiting fluid contact exclusively to non-metallic components.

The adjustable sliding inboard bearing design provides for quick and easy mechanical seal inspection or readjustment without disturbing the piping, while minimizing shaft deflection and impeller overhang, prolonging seal life. The open seal area accommodates most commercial seals including single, double, cartridge and balanced arrangements.

Optional features include leak detection, temperature monitoring, and run-dry protection devices.

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

This pump available with recessed Vortex impeller for slurries and fluids containing stringy materials or solids to 2 in. (51 mm) in diameter.
