Alignment in Your Maintenance Strategy – Calculate ROI!

More than 50% of all pump damage is caused by misalignment! Let’s hypothetically assume we are operating 95 assets with a mix of 50-200 HP pumps. In this example each of those pumps is misaligned by 15 thousands (offset). The calculation of AES returns a 23.2 months replacement interval and a 0.5% power increase in consumption as per ICI research. We encounter four saving categories. Power consumption, seal and bearing replacement and pump repair cost. If we assume that the electricity cost is 12 cent/kWh (US average) and the pump repair cost requires 100$/h manpower one can save $172,260.00 per year if all pumps are aligned to 0.05 thousands.
