Install pump, driver, and v-belt drive
Install and align the sheaves
Before installing the driver onto an overhead motor mount or side-by-side base, ensure that
Foundation requirements and baseplate mounting procedures sections are complete.
1. Mount and fasten the pump on the pedestal spacer, foundation, or baseplate as applicable.
Use appropriate hardware.
2. For a motor that is mounted overhead, install the overhead motor mount.
3. For a motor that is mounted to the side of the pump, fasten the motor slide base on the
baseplate or pump. Fasten the motor slide base on the baseplate or foundation, as
applicable. Use appropriate hardware.
4. Mount the driver on the overhead motor mount or slide base, as applicable. Use
appropriate hardware.
5. Install the v-belt drive bushings and sheaves. See the installation instructions from the v-
belt drive manufacturer.After the v-belt drive bushings and sheaves are installed, check the
sheave alignment using a straight edge as shown in the following diagram.
1. Straight edge
2. Incorrect
3. Correct
NOTICE:
Make sure that the sheaves are properly aligned. Proper alignment is necessary to guarantee
the correct power transmission and speed ratio, and ensures minimum vibration and long drive
life.
Install and tension the belt
1. After alignment of the sheaves, reduce the center distance between the pump and motor
shafts so that the belts can be easily mounted into the sheave grooves.
For...
Reduce the center distance by...
Overhead mounted motors
Adjusting the leveling nuts
Side mounted motors
Adjusting the motor slide base
Make sure that the center distance between the pump and motor shaft is reduced to the
point where the belts can be put on the sheaves without the use of force. Never roll or pry
the belts into place, as this could damage the belt cords.
2. After the belts are seated in the sheave grooves, increase the center distance between the
pump and motor shafts to tension the belts.
