Selection
The flow velocity through the discharge pipe must be
minimum 2.3 ft/s to ensure self-cleaning.
Example: Schedule 40 PVC discharge pipe with an
inner diameter of 2.067" requires a minimum flow
velocity of approximately 24 gpm.
The overview below shows the maximum lengths of
combined vertical and horizontal Schedule 40 PVC
discharge pipes.
The overview is only intended as a guide. Grundfos is
not liable for installations not complying with the
overview.
Note: If a non-return valve is used, the pressure drop
in the valve is approximately 0.6 ft head which must be
subtracted from the vertical pipe lengths.
The vertical height of the discharge pipe should be
measured from the pump stop level.
