Waste water pumps (GÜLICH)

For waste water pumps the slip mainly depends on the number of blades.

The table contains typical values for the slip coefficient γ:

number of blades

slip coefficient γ


0.48 ... 0.6


0.53 ... 0.65


0.67 ... 0.75


Inducer pumps (GÜLICH)

For inducer pumps the deviation angle depends on the blade angles on leading and trailing edge and the solidity.
