Why prefer the CPO over competitor brands?
- Lower NPSHr due to the computerized impeller design
- More robust Power Frame due to larger bearings than competitors
- Bearing life of 50000 hours at BEP, max speed and max impeller diameter
- Plate retainer for axial bearing instead of snap ring increases the bearing life, reduces vibration and eliminates end shaft play
- Micrometer impeller setting feature. It’s easier to set the impeller clearance vs the jack screw method used by competitor
- Inpro VB45-S bearing isolator as standard. This effectively seals bearing housing when shutdown, makes oil and bearings last longer by eliminating contamination
- 360° sight glass from Luneta doesn’t cloud and offers high strength
- Larger oil sump than competitors
- Fit all these features to a competitor pump with a simple shaft change
