The "Original" Floating Strainer
Float Dock® Strainer

FOL-DA-TANK® Company manufactured the first floating strainer in 1954 and started selling them in 1955. 
The Float-Dock® proved to be the most practical answer not only for firefighting but also for construction and minning operations.

Pump pond water free of debris with Float Dock® floating strainer


The 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)


Construction Features:

  • Professionally designed & engineered for maximum pumping capacity
  • Polyethelene molded float with molded in carry handle (handle can be used for tie off and retrevel)
  • No need for a vortex plate.  The float prevents any whirlpooling.
  • Self-Leveling
  • Not hand welded
  • Al-Mag castings  - Proven to be the toughest in the industry
  • Long handle swivels with standard NH or NPSH threads
  • 20-30% more open area at the intake
  • Other threads available
  • Detach strainer and use separately as a "Box Strainer"
  • All Float Dock® are available in all aluminum construction up to 8" (See Below)
  • Float Dock® drafts in as little as 5 inches (13) cm of water
  • Optional riser will convert the strainer box into a low-level strainer



In deep water, Float Dock® drafts clean water below the surface.
In less than 30 seconds, strainer can be removed for use in cisterns.

Float Dock® in use in cold climate.

Side Wall Low Level Strainer




Side wall strainer for "through-the-wall" dump tank use.  The "Water Shark," Side Wall Strainer, eliminates several problems currently known with existing Low Level Strainers.  The Water Shark increases the overall efficiency and flow of the system while providing free access around the outside of the dump tank.  Call for pricing.

Design Features:

  • Light weight powder coated Aluminum.
  • Quick set-up, attaches in seconds using a custom design Cam Lever clamp band.
  • Large 46" x 2.5" wide intake area provides a 4.4:1 strained intake ration.
  • Guide veins inside create 5 seperate intake zones.

  • Eliminates trapped air pockets noticable on current up and over hose designs.
  • "U-shape" intake provides inlet of water on three sides (front, bottom, and back).
  • Custom molded feet protect the liner from puncture and suspend the strainer 1/2" from the bottom of the liner.
  • Side attachment eliminates jet wash issues.  Also, allows easy walk access around the dump tank.
  • Can be retrofitted to existing dump tanks in the field.  Mounts to either aluminum square frame or round steel frame.




Power Jet Siphon


The Power Jet Siphon is designed for use with two or more Fol-Da-Tanks. The siphon connects to a hard suction hose and assists the transfer of water from one tank to another.  This keeps the main tank full of water for drafting as the secondary tank is refilled.  The construction features include: durable al-mag alloy, aircraft quality tubing and 1 1/2” female assist by 4” - 6” discharge couplings.  Standard threads are NST with other threads available.  Storz and cam fittings are available upon request.  (NFPA 1142 compliant)
