12.2 Connection to the piping
Before connection, clean the piping and remove foreign bodies such as welding
residues.
Avoid forces and torques acting from the piping on the pump connections (e.g.
distortion, expansion due to temperatures etc.) by using compensators or other
suitable equipment.
The user must ensure that a pressure rise above the pressure agreed in the
purchase order and listed in the technical data sheet is not possible.
MasoSine pumps normally run with such a low resonant frequency that no damage
results. However, particularly when running with inverters, certain frequencies can
cause interference vibrations which must be avoided. It is important during
commissioning to ascertain whether such vibrations exist and to define them, so
that the inverter can be programmed to avoid these frequencies. Similarly,
interference from cavitation or rigid lines must be avoided.
