    • Increase abrasive resistance with Life Guard Seals 
      • Life Guard seals are the OEM standard
    • Extend pump life with Stainless Steel
      • Fact: Chemical corrosion, pump cavitation, and abrasive wear are key factors in pump life
      • 316 Stainless Steel pumps provide superior chemical corrosion resistance, while maintaining material strength to prolong the life against abrasive wear
      • 316 Stainless Steel resists cavitation pitting of pumps, extending the wear life
      • Drop in replacements for cast iron pumps
