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.
