Horizontal Multistage Pump — TCO Savings Calculator

Estimate the 10-year total cost of ownership for an OEM-grade horizontal multistage pump versus a low-end equivalent. Based on ITT Goulds’ published TCO methodology: initial cost ≈ 10% of TCO; non-OEM pumps run roughly 10.25% lower efficiency on average.

This calculator uses industry-benchmark efficiency gap (10.25% per ITT ANSI pump testing) and assumes the low-end pump runs at the same duty point but draws proportionally more power. Maintenance factor default of 1.8× reflects the published ITT case of chemical-plant MTBF improvement (15.4 mo → 32.1 mo after quality engineering). Substitute your own numbers for a tailored view.
