Stationary wet well installation

For stationary wet well installation, the pump is installed directly onto the pressure pipe. Observe and adhere to the following points:

  • The connected pressure pipe must be self-supporting. The pressure pipe must not be supported by the pump.
  • The pump may oscillate slightly during operation. These oscillations must be dissipated via the pressure pipe.
  • Ensure that the connection to the pressure pipe is stress-free – do not screw it in too tightly.
  • The pressure pipe must not be smaller than the pump’s discharge connection.
  • Seal pipe connections with Teflon tape.
  • Install all specified valves in accordance with local requirements (gate valve, non-return valve).
  • Lay the discharge pipe frost-proof.
  • Air pockets in the pump and in the discharge pipe can lead to delivery problems.
  • Installing the ventilation systems:
    • For example, air vent valve
    • In the discharge pipe
    • Before the non-return valve
  • Install the discharge pipe as a “pipe loop” to avoid backflow from the main public sewer.
  • At its highest point, the bottom edge of the pipe loop must be above the locally determined backflow level!

  1. Site is prepared.
  2. Pressure pipe properly installed.
  1. Screw the discharge pipe fully into the pump’s discharge connection.
  2. Position the pump at the installation site.
    CAUTION! Use a hard surface or underlay at the installation site to prevent sinking on soft substrate.
  3. Connect the discharge pipe to the pressure pipe (e.g. using a flexible hose section).
  4. Secure the connection cable to the pressure pipe and route it to the socket/power supply.
