6)
For any fluids which are not listed in this table contact KSB.
7)
The first impeller type listed should be given preference.
9)
Severe hydroabrasive wear occurs if solids contents of approx. 0.5 g/l or higher are combined with circumferential speeds
exceeding 20 m/s or low-flow conditions to the left of the duty point.
10)
The material variants required highly depend on the operating hours, rotational speed and flow velocity.
