Drive Options for Angle Application Pumps
The following drive arrangements are applicable to both
Axial Flow and Turbine pumps.

Extended Drive Column. This option is available on any pump, to place power plant and transmission above flood level, or to allow the Discharge Head to be placed below ground. 

DRIVE OPTIONS
Safety guards (not shown) are fitted as standard.

1) DIESEL, universal shaft, angle gear drive.
A suitable gear ratio is selected, to place the engine RPM in the optimum operating range.

Avoids vee-belts.  High efficiency, long running.

2) DIESEL, universal shaft, direct coupled.     

Suitable for use when pump RPM falls within the optimum operating range of the engine. Avoids vee-belts.  High efficiency, long running.

3) ELECTRIC foot mounted motor, universal shaft.  Suitable for use when pump RPM matches motor speed, or when Electronic speed control is available. Avoids vee-belts.  For independent mounting of large motors.

4) ELECTRIC, flange mounted, solid shaft, direct coupled.  Suitable for use when pump RPM matches motor speed, or when Electronic speed control is available

5) ELECTRIC, hollow shaft, direct coupled.
Similar to option  4) above, except that this class of motor is more robustly built and compact.

Pump spindle extends through the hollow motor shaft, impeller thrust is taken by motor bearings.  Avoids use of pump thrust bearings and flexible coupling, thereby simplifying dismantling of pump.  Limited to special motors.

6) ELECTRIC, Foot mounted, vee-belt drive.
Vee-belts provide the lowest cost method of matching the RPM of motor and pump, when it is not possible to select an impeller to match the motor speed.  Discharge rate may be altered by changing pulleys.  Adjustable motor mounts attach to the Discharge Head.
