5 Start-up
The NEMO
®
pump design requires strict attention to the following:
Never run the NEMO
®
pump dry!
A few rotations in dry condition will damage the stator!
■ Before starting up for the first time, fill the pump with medium. In the case of high
viscosity media fill with a liquid.
Pump priming is vital to ensure lubrication of the rubber stator. Fill the piping on the
pump suction side. In anti-clockwise rotation only: Fill the pump housing.
The NEMO
®
pump is a progressing cavity pump which can produce
pressures that may cause the bursting of vessels or pipes.
The power transmission train (shaft, coupling rod, joints, rotor) of
the pump may be overloaded thus resulting in damage or breakage.
Also the pump housing parts with their connections may be
overloaded and break. There is a table in Section 4 of these
Maintenance and Operating Instructions showing the pressure
resistance of the pump housing parts.
Never run the pump against a closed inlet or outlet valve!
