Component Specifications

Definition
Nozzles are engineered fluid distribution components integrated into underdrain systems of industrial filtration equipment, designed to ensure uniform distribution of backwash water, air, or process fluids across filter media. They feature precise orifice geometries and flow patterns to optimize cleaning efficiency, prevent media loss, and maintain consistent filtration performance in applications such as water treatment, chemical processing, and beverage production.
Working Principle
Nozzles operate by converting pressure energy into controlled kinetic energy through precisely designed orifices, creating uniform fluid jets or sprays. In underdrain systems, they distribute backwash fluids evenly across the filter bed, dislodging trapped particles while preventing channeling. The Bernoulli principle and fluid dynamics govern flow rates, with laminar or turbulent patterns selected based on media type and cleaning requirements.
Materials
Stainless steel (AISI 304/316), PVC, polypropylene, ceramic, or brass; selected for corrosion resistance, mechanical strength, and compatibility with process fluids. Materials must withstand temperatures from -20°C to 120°C and pressures up to 10 bar.
Technical Parameters
  • Flow Rate 2-50 L/min per nozzle
  • Pressure Range 1-6 bar
  • Surface Finish Ra ≤ 0.8 μm
  • Connection Type Threaded (NPT, BSP), snap-fit, or welded
  • Orifice Diameter 0.5-5 mm
  • Temperature Rating -20°C to 120°C
Standards
ISO 2852, DIN 11851, ASME B16.11
