HydroWhirl S Tank Washing Nozzles

Tank Cleaning Nozzles, Rotating Slotted Spray Nozzles

We Can Help
  • Cleans more quickly, but uses less water and lower pressure than static tank washers
  • Lower flow and pressure mean smaller pump size resulting in lower operating costs
  • Surface finish ideal for sanitary applications
  • Laser welded design - durable assembly
  • 316 stainless steel construction - corrosion resistant
  • Three connections - threaded, clip-on, and welded
  • Made from FDA-accepted materials for Clean-in-place (CIP) applications
  • Self-cleaning bearings
  • Vigorous moving spray action
  • Complete 360° omnidirectional coverage
  • Additional spray angles:
    90° Down
    180° Up

HydroWhirl® S slotted rotating spray nozzle for quick, efficient tank cleaning

The HydroWhirl® S tank washing nozzle directs the cleaning water through a rotating head at the tip of the spray assembly. This produces a vigorous moving spray action against all areas of the walls of a tank. The spray pattern from the HydroWhirl S head uses impact and repetition to quickly wash the tank. This spray pattern is especially effective at breaking up and removing contaminants.

Optimal cleaning performance achieved at 60 psi (4 bar); MAXIMUM operating pressure is 150 psi (10 bar).

Low-maintenance bearing design:

  • Self-cleaning bearings are lubricated by water flow to clear away particles

High-precision machining and finish:

  • 316 stainless steel construction - durable and corrosion-resistant
  • Made from rolled steel, not forged - no internal stress points
  • Surface finish of 0.8 microns Ra or better
  • 100% welded assembly

Comprehensive quality control:

  • Material traceability controlled throughout production
  • Lab testing validates minimum service life of 300 hours

Design flexibility:

  • Available in many different sizes and connection styles
  • Dual bearing design - nozzle operates effectively in any orientation
     
The HydroWhirl S tank washing nozzle is an outstanding combination of design, quality, and engineering and is ideal for anyone who needs reliable, efficient cleaning of tanks and other interior spaces.
