ZY Cyclone separators

ZY Cyclone separators

ZY Cyclone separators

Features

The ZY range (shown: ZY1) is available in three basic versions:

ZY1:
  • Cyclone separator in stainless steel cast without replaceable insert
  • ZY2:
    • Cyclone separator with replaceable ceramic insert
    • ZY3
      • Higher flow rate as ZY2

Advantages

  • Contaminations are automatically conveyed to the suction nozzle of the pump: maintenance-free mode of operation for guaranteed reliability
  • High filtration efficiency
  • Wide range of products for the optimum solution for every application
  • ZY2 and ZY3: for operating pressures of up to 200 bar
  • ZY2 and ZY3: optional in block-type design with integrated flange connections: low space requirements because of compact design

Functional description

Cyclone separators of the ZY range are used to clean mainly aqueous liquids containing dirt and solids (e.g. in circulation systems of sewage, sludge or pipeline pumps). The best possible filtration efficiency is achieved when the specific weight of the solids is much higher than that of the carrier liquid (recommended by API 682 4th edition: at least double), and when the differential pressure is as large as possible within the permissible pressure range (min. 1.7 bar in accordance with API 682). The viscosity of the medium is also a factor that needs to be taken into account.
