VAF Hydrocyclone Separators are effective in removing suspended particles from any flow stream of water where the specific gravtity (density) of the particle(s) is heavier than the water it is in; the more significant the difference in the gravity between the water and the particle, the greater the efficiency of the removal process.  Depending on the specific gravity of the particle and the viscosity of the flow stream, very small and denser particles can be removed. Particulate removal can be enhanced if multiple passes of the stream can be achieved. Consider a separator's use where any source of water contains contanimants with a weight of 2.6 specific gravity or higher, such as well water to remove sand.  Separators are also excellent for use as a pre-removal device for filters with river or ditch water that contain high levels of sand or other large organic debris.

Applications would include, but not be limited to, wells, industrial processes, water recycling and reuse, river and ditch water intake systems, food processing nozzle systems and irrigation water.

An automatic purge controller and valve can be used on all applications.  This eliminates the need for manual flushing, turning the separator into an automatic system. 

Small separators can be wall mounted, hung on the main piping, or placed on legs if desired.

Pump Intake Suction Strainer:

VAF's Self-Cleaning Pump Intake Suction Strainer is galvanized or epoxy coated and utilizes a heavy 12, 18, or 24 mesh stainless steel screen designed to increase pump efficiency. The screen continuously removes debris from water. This saves time and money in fuel, pumping efficiency, and maintenance costs. The Self-Cleaning Suction Strainers can be used for agricultural, turf, industrial, centrifugal, or turbine pump applications.


The suction strainer is attached to the end of the pump in the water source. All water pulled in must traverse the screen before entering the intake pipe. The screen stops trash and debris from entering and causing costly maintenance requirements in your system. The pump discharge return line drives two spray bars that continually rotate, jet water at the screen, and blast debris away from the screen at 2.8 to 4.5 bar (40 to 65 psi) operating range.

BE-Series Automatic Brush Strainers:

Standard Features:

  • Inlet/outlet on an axis of 90° (horizontal or vertical)

  • Strainer housing material of construction: Carbon Steel

  • Strainers are electrostatically coated with polyester at a thickness of 150-200 micron and oven cured.

  • Strainers are supplied with a stainless steel wedgewire screen, available in varying micron size as needed: 200-4000 micron.

  • Inlet/outlet: Flanged 4" - 16" 

  • Maximum recommended working pressure: up to 10 bar (150 psi)

  • Minimum operating working pressure during flushing: 1 bar (15 psi)

  • Clean screen pressure loss: up to 0.1 bar (1.5 psi)

  • Control voltage: 380/220 VAC, 3 phase, 0.5 HP motor

  • Control system: electric control board 380/220/120/24 VAC

  • A time basis backup (preset by the operator) guarantees that the flushing cycle will occur even if the head loss has not triggered a flush cycle.
