Batescrew Axial Flow Pumps.
Angle Application - Description.

Axial Flow    Construction Materials;   Lubrication Options;   Design Calculations;
Capacity Selection;   Impeller Curves;   Extended Drive Column.
When used on a river  bank, an angle application pump presents the least obstruction to river flow, causes less bank disturbance and requires less infrastructure than would a vertical pump.

The pump axis is inclined 36deg. from horizontal, simplifying support structures on riverbank and storage dam installations.  Pumps are usually installed on slide rails, anchored to the bank, aiding installation and retrieval for maintenance.   (see Slide Rail Dimensions

Discharge may be either above or below ground.  An extended drive column may be fitted, keeping power unit and thrust bearings above flood level.
