Self-Leveling Float Dock Strainer

The Self-Leveling Float Dock Strainer is a valuable piece of equipment that can save the day in many firefighting situations.

Float Dock® lets you use the water in farm ponds or streams, both shallow and deep, and with a FOL-DA-TANK.

Because it operates below scum and debris and above sand and muck, it screens out the materials that wear out impellers, packing, and bearings.

Since Float Dock® strainers are self-leveling, there are no whirlpools or suction loss. Each unit is fully guaranteed. (NFPA 1142 compliant)


  • Professionally designed and engineered for maximum pumping capacity.
  • Polyethylene molded float with molded in carrying handle (handle can be used for tie-off and retrieval).
  • No need for a vortex plate. The float prevents any whirlpooling.

  • Long handle swivels with standard NH or NPSH threads.
