Product details

  • SANDPIPER Heavy Duty Flap Valve Pumps provide a reliable and efficient solution. They are designed with easy access flap valves and top suction and bottom discharge porting. 

    • Line-size solids handling
      Flap valve versus ball valve pumps
      • Flap check valve pumps: A large flow area allows up to 3"/4" line-size solids to pass directly through the pump. Additionally, bottom discharge porting allows settling solids to pass through the pump and not settle inside the pumping chamber, preventing damage and premature wear.
      • Ball check valve pumps: Much less flow area for solids to pass through. Large solids get stuck in the suction manifold and small solids can settle in the outer chamber–both issues affect pump performance.
    • Superior suction lift
      Flap valve versus ball valve pumps
      • Suction lift advantage: SANDPIPER’s flap valve design provides superior suction lift capabilities up to 24 ft in water. Diaphragm placement and flap valve seating combine to create a unit capable of suction lifts 15% greater than ball valve pumps.
      • Dry prime: These capabilities are from a dry prime, making the SANDPIPER flap valve pump an excellent solution for situations where limited choices are available for pump priming.
