Stationary wet installation
1 | Gate valve |
2 | Non-return valve |
3 | Discharge line |
4 | Discharge pipe with Rp 1½ |
5 | Ventilation drilling (3 mm/US drill bit size: 1/8) |
6 | Optional: Float switch for high water level |
7 | Optional: Alarm switchgear, e.g. DrainAlarm |
ON | Switching point: pump on |
OFF | Switching point: pump off |
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.
- Discharge pipe with Rp 1½ internal thread. Prepared with the length from discharge port to discharge line.
- Flexible hose (internal diameter: 50 mm/2 in) for connecting the discharge pipe to the discharge line.
- Two pipe clamps (diameter: 45 to 60 mm/1.75 to 2.4 in) for fastening the flexible hose.
- Screw the discharge pipe into the discharge port.
- Put the flexible hose on the discharge pipe.
- Put the two pipe clamps on the discharge pipe.
- Set up the pump on site.
- Slide the flexible hose over the two pipes.
- Fasten the flexible hose with the two pipe clamps.
- The pump is installed.
