On a river bank,
this configuration presents the least
obstruction to river flow, causes less bank disturbance and requires less
infrastructure than would a vertical pump.
Convenient installation and retrieval from river-bank and water storages.
Pump axis is commonly inclined
within the range of 15deg to 45deg from horizontal. Pumps are
usually installed on slide rails, as seen here, aiding installation
|Discharge may be either above or below ground. An extended drive column may be fitted, keeping power unit and thrust bearings above flood level.|
