World Chemical GS and GSF horizontal magnetic sealed pumps

Glass Filled Polypropylene (GFR PP) and Carbon Filled (CFR) ETFE designed for reliable service life - closed coupled with TEFC motors.  PPS (polyphenylene sulfide resin) internal bushing helps radiate heat during periods of dry-running.  Standard shaft materials is 99.5% high purity ceramic.  

Compact Series

16 GS - 16GSH - 20GS   - 1/4 or 1/3 HP with high flow impeller offer flow rates to 35 GPM or high pressure impellers for pressures to 63 feet.  

Specifications

  • 1" FNPT inlet x 1" MNPT outlet - hose, flanged and unions upon special request.
  • Temperatures to 158F
  • Specific gravity - GFR PP  - 1.1 or CFR ETFE up to 1.9*
  • PTFE bushing with high purity ceramic shaft
  • FPM or EPDM head O-ring

Motors 

  • V-ring and oil seal enhancements for additional resistance of corrosive attack to extend the life of the motor
  • 16GS or GSF - 1/4 HP - 115V/1 or 230V/3
  • 16GSH(F) or 20GS(F) - 1/3 HP - 115V/1 or 230V/3

* Note:  ETFE impellers are trimmed for high specific gravity solutions of 1.1, 1.5 or 1.9
            ETFE model number end with the letter F  ie:  20 GSF

  Bulletin  - Additional information

400 Series  High Performance with flow rates to 150 GPM

Design Highlights

  • Corrosion resistant materials provide leak free service - glass or carbon filled resigns provide additional mechanical strength
  • Polypropylene base support isolates motor from baseplate
  • PPS bushing system provide for wear resistance and excess heat during periods of dry-running.
  • Internal rings in rear casing release air pockets to prevent air locking problems
  • Neodymium magnets used for 2 HP and above pumps  
  • NPT or flanged connections for GFR PP (GS) - Flanged standard for CRF ETFE (GSF)

Specifications

All 400 Series

  • Precision molded CRF polypropylene (GS) or CFR ETFE construction (GSF)
  • Alumina ceramic shaft and rear thrust ring - SiC option
  • Impeller bushings options - carbon, ceramic, PTFE, SiC
  • CRF PTFE impeller mouth ring bushing
  • GFR polypropylene mounting base - motor feet not exposed to baseplate

    Note:  ** Impellers trimmed for higher specific gravity - see performance curves
    PPS is polyphenylene sulfide resin 
    CFR - carbon filled resin used with ETFE for added material strength
    GFR - glass filled resin used with polypro for added material strength
