FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06
If necessary, improve the machine alignment:
Complete unit mounted on common base plate: The machines are first aligned accurately in our workshops. Usually, any misalignment observed on- site is due to a wrong adjustment under the base plate (disturbed during transport or because of forces exerted by the pipework). It is only necessary to rectify the adjustment under base plate. If it proves to be insufficient, modify the motor and the pipeworks adjustment.
Pump and motor mounted on individual base plates:
Machines are (or must be) first mounted on their own base plate in the workshop. Once the pump is set, it will be regarded as the fixed piece. Any alignment necessary shall be carried out on the motor.
Never connect the electric motor before the setting has been completely finished.
4.5 Piping
The user must verify that the equipment is isolated from any external sources of vibration.
Protective covers are fitted to the pipe connections to prevent foreign bodies entering during transportation and installation. Ensure that these covers are removed from the pump before connecting any pipes.
4.5.1 Suction and discharge pipework
The dimensions of the pipes do not directly depend on suction and discharge diameters of the pump.
a)First, choose a flow speed < 2 m/s at suction, and about 3 m/s at discharge.
b)Take into account the available NPSH, which must be superior to the required NPSH of the pump.
Never use pump as a support for piping.
Do not mount expansion joints in such a way that their force, due to internal pressure, may act on the pump flange.
Maximum forces and moments allowed on the pump flanges vary with the pump size and type. These external strains may cause misalignment, hot bearings, worn couplings, vibrations and the possible failure of the pump casing.
When designing the pipes (§ 4.5.2.1, § 4.5.2.2, § 4.5.3.1) take necessary precautions in order not to exceed maximum allowed strains.
Forces and moments applied to the pump flanges must never exceed the values shown in the table below:
