Check that the installed rotors run smoothly. The easiest way
of doing this is by turning the drive shaft
clockwise
with an
appropriate amount of force using a hexagon socket wrench
or a ratchet.
If correct true-running is not obtained, the cause must be
determined and the installation must be corrected.
NOTE!
Smooth running
"Smooth running" means a uniform, trouble-free true-run-
ning (concentricity) without any blocking.
— Providing the pumped medium and materials used allow
this, the rotors can be coated with liquid (e.g. soft soap)
for the smooth running check.
— When dry, polymer rotors can only be rotated with a cer-
tain degree of force, as they are positioned close to the
pump casing.

Before releasing the rotary lobe pump, check once again that

If correct true-running is not obtained, the cause must be
determined and the installation must be corrected.
