Sulzer submersible recirculation pump XRCP

  • Compact design.
  • Maintenance friendly.
  • Very good hydraulic efficiencies.
  • High operation reliability.
  • Simple installation.


The Sulzer submersible recirculation pumps XRCP are supplied with the wellproven automatic coupling system using a single guide rail.

The Sulzer single guide rail coupling system guarantees quick and economical installation. The DIN-fl ange of the discharge line (supplied by the customer) forms the connection flange of the Sulzer automatic coupling unit. A guide rail joins the connection flange with the pipe retainer at the top of the tank.

The XRCP is connected on to the guide rail and can be lowered easily. It reaches its correct operating position automatically and is immediately ready for use.

Application areas

The Sulzer submersible recirculation pumps XRCP have been designed for pumping activated sludge in treatment plants during the nitrification and denitrification process, as well as for pumping of storm, surface and river water.

As all Sulzer submersible pumps and submersible mixers they have been designed for economical and reliable operation.
