Note on pipework

The pipework is subjected to different pressures during operation. Pressure peaks can also occur (e.g. when closing the swing check valve) which may be several times higher than the pump pressure, depending on the operating conditions. These different pressures put a strain on the piping and the pipe adaptors. In order to ensure safe and faultless operation, the piping and pipe adaptors must be checked based on the following parameters and designed according to the requirements:

• On-site pipes are self-supporting.
• No tensile or compressive forces may act on the lifting unit.
• Pressure resistance of pipework and pipe adaptors
• Tensile strength of the pipe adaptors (= longitudinal force fit connection)
• Connect the pipes free of stress and oscillations.
• Provide a gate valve in the inlet and the discharge line on-site!
