Gravity Filter

Pressure-free self-cleaning UDI Gravity Filter:

An energy-efficient method for the filtration of large capacities with minimum inlet pressure. Suspended dirt particles are trapped and swept towards the drain. The water is pumped up a few meters and brought into the top of the filter. Passing through a stainless steel screen, the dirt is swept together in the direction of the drainage device. Dirt particles that threaten to get stuck are sprayed upwards by a rotating (jet) sprayer arm. This combination keeps the screen clean, allowing the filter to work continuously. With a minimum of pressure and rinsing water the filtered water is available for various applications.

Advantages of the UDI Gravity Filter:

  • Water is supplied at very low pressure.
  • Minimum amount of energy required.
  • Simple, reliable design.
  • Cleaning of the filter screen does not interrupt the process.
  • Efficient and automatically self-cleaning system.
  • No water loss during the cleaning of the stainless steel filter screen.
  • Minimum amount of waste water in a drainage cycle.
  • Low operating costs.

Coating:

In preparation for the coating to be applied, the UDI filters are provided wit a special layer of zinc phosphate. This treatment ensures proper adhesion of the coating, and protects against rusting-through from the insde. Subsequently , the polyester coating is applied electrostatically, both internally and externally, before being furnace-hardened. The entire process involves 7 steps, and results in a perfect coating with a thickness of approximately 120 microns.
