For stationary wet installation, install the pump directly on the discharge line. Obey these points for installation:

  • Make sure that the discharge line is self-supporting and not supported by the pump.
  • The diameter of the discharge line is the same or larger than the diameter of the discharge port.
  • Make sure that the discharge line is installed frost-proof.
  • Seal the pipe connections with Teflon band.
  • Install all necessary fittings according to the local regulations (gate valve, non-return valve).
  • When submerging the pump, prevent air bubbles which can cause pumping problems. To vent the pump, follow one of these points:
    • Install an air vent valve before the non-return valve.
    • Drill a 3 mm hole in the discharge pipe above the discharge port.
  • To prevent backflow from the public sewer, install the discharge line with a “pipe loop”.
  • The lower edge of the pipe loop must be above the locally set backwater level at its highest point.

Stationary wet installation
  1. Discharge pipe with Rp 1½ internal thread. Prepared with the length from discharge port to discharge line.
  2. Flexible hose (internal diameter: 50 mm/2 in) for connecting the discharge pipe to the discharge line.
  3. Two pipe clamps (diameter: 45 to 60 mm/1.75 to 2.4 in) for fastening the flexible hose.
  1. Screw the discharge pipe into the discharge port.
  2. Put the flexible hose on the discharge pipe.
  3. Put the two pipe clamps on the discharge pipe.
  4. Set up the pump on site.
  5. Slide the flexible hose over the two pipes.
  6. Fasten the flexible hose with the two pipe clamps.
  1. The pump is installed.
