Hydrocyclone Separators

Hydrocyclone With Sedimentation Tank

Netafim Hydrocyclone Separators separates solid matter from water with better than 90% efficiency rating. Removes solids, alleviating dirt load for the backup filter. Pumps, valves and water systems are protected from damage and abrasion caused by debris, lowering maintenance and replacement costs and adding years of performance to the life of your leaching system.

Features & Benefits

  • Conical shape accelerates the velocity of the water increasing the centrifical forces and maximizing separation.
  • Easy to operate and maintain with no moving parts or screens.
  • No headloss build-up or clogging during separation.
  • Large holding capacity of sedimention tank reduces flushing frequency.
  • Maximum anti-corrosion protection with durable and long-lasting coating materials.


  • For separation of sand and other solid matter from water
  • Protection of valves and irrigation systems from damage/abrasion caused by sand and other solid matter
  • Pre-filtering of water with high loads of sand before gravel, disc and screen filters

Hydrocyclone Separators Technical

Description of Operation

Based on the centrifuge principle, the particles are spun against the outside wall of the Hydrocyclone and gravitate towards the bottom into the underflow chamber (sedimentation tank) while clean liquid moves upward to the center of the spiral, towards the top outlet. The velocity at which the particles are separated from the water.

  • Normal working conditions are achieved when headloss on the Hydrocyclome is not less than 3 psi. A headloss of less than 3 psi will reduce the separation efficiency and a headloss of more than 8 psi might induce increased erosion.
  • The flow during oepration of the system needs to be fairly constant to ensure effectiveness of separator.


  • Maximum working pressure: 120 psi
  • Recommended headloss for effective operation: 3 to 8 psi
  • 100 Micron Polyester Oven Cured protective coating with Zinc Phosphate under-layer
  • Water Inlet and Outlet: Horizontal and Vertical
  • Hydrocyclone End Connections: Thread, Flange and Groove
  • Sedimentation Tank Connections:
    • Thread – 3″ and 4″ sizes
    • Groove – 6″ and 8″ sizes
    • Flange – 12″, 16″, 20″, 24″ and 30″ sizes
  • Rubber Insert not included on 3″ and 4″ sizes


Find your system flow rate and move vertically up the chart until you intersect within the recommended range. This indicates a particular hydrocyclone size. If your flow rate does not intersect within the recommended range, two smaller units in combination are suggested. If material to be removed is extremely fine, use a higher headloss and/or multiple huydrocyclone units of a smaller size. A smaller hydrocyclone can remove finer particles than one with a larger diameter.
