Installation
system, install all components in accordance with the manufacturer's instructions. Check belts and pulleys every 2000
hours.
3.8 Direct drive booster pump installation
Drive coupling alignment must be correct. Misalignment or a worn out coupling spacer (spider) will damage the
booster pump bearing and seal(s). Comply with the installation requirements specified in this manual and inspect the
drive system regularly, to avoid mechanical problems and unnecessary repairs.
If you install your own motor and drive components, they must comply with all local and national safety regulations.
Follow all of the safety precautions outlined in Section 3.1.
Direct drive booster pumps are supplied with the motor coupling already set. Recheck the alignment before initial
operation. Values listed below are for L190 couplings. Contact Edwards for advice on other coupling sizes. Check the
condition of the coupling spider every 2000 hours.
1. Ensure that the shaft, coupling and other components are free of lubricants, protective coatings and burrs.
2. Slide one half-coupling onto each shaft. Check that the keys fit tightly.
