Vacuum Pump Cost at 99% hours assigned to production: a worked example

This scenario runs the vacuum pump cost calculation on the strong side: 99% hours assigned to production, with every other input held at its documented default. Use it when reviewing vacuum pump cost for a utility budget, maintenance priority, capacity check, energy project, or production support plan.

The inputs for this scenario

  • Vacuum pump operating hours: 240 hr (unchanged)
  • Vacuum system cost per hour: 9.5 $ / hr (unchanged)
  • Hours assigned to production: 99 % (raised for this scenario; the documented default is 90)
  • Oil, seal, and filter adder: 175 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total vacuum pump cost = vacuum pump operating hours × vacuum system cost per hour × hours assigned to production + oil, seal, and filter adder) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,432 $ for total vacuum pump cost, the number this scenario is built around.
  • At this operating point the engine returns 10.13 $ / item for cost per item or period.
  • At this operating point the engine returns 2,257 $ for variable vacuum pump cost.
  • At this operating point the engine returns 175 $ for fixed utility adder.

How this compares with the baseline

  • Against the tool's baseline example, where hours assigned to production sits at 90% and the headline result is 2,227 $, this scenario comes in 9.21% above the baseline at 2,432 $.
  • Use it to allocate vacuum cost to a product or line, compare pump technologies, or set a baseline before an energy or consumables reduction project. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total vacuum pump cost: 2,432 $ (headline result)
  • Cost per item or period: 10.13 $ / item
  • Variable vacuum pump cost: 2,257 $
  • Fixed utility adder: 175 $
