Selection
The below overview is suitable for the selection of the correct size of Unilift KP pumps used in stationary applications.
The flow velocity through the discharge pipe must be minimum 0.7 m/s to ensure self-cleaning.
Example: A DN 32 discharge pipe with an inner diameter of 26 to 34 mm (depending on local standards) requires a minimum
flow velocity of approximately 2.3 m

/h.
The overview below shows the maximum lengths of combined vertical and horizontal DN 32 discharge pipes.

Overview of maximum lengths of combined vertical and horizontal discharge pipes
The above overview is only intended as a guide. Grundfos is not liable for any faulty installations based on the overview.
Note: If the non-return valve is used, the pressure drop in the valve is 0.2 m head. The pressure drop is to be subtracted
from the vertical pipe lengths.
The vertical height of the discharge pipe should be measured from the pump stop level.
