Coating Cost per Pump at 110% share receiving full coating system: a worked example

Push share receiving full coating system up to 110% and the picture changes. This example computes every intermediate figure at that operating point. a pump shop needs to cost epoxy or fusion-bonded coating for a batch of casings before quoting or scheduling the booth

The inputs for this scenario

  • Pumps to coat: 60 pumps (unchanged)
  • Coating cost per pump: 140 $ / pump (unchanged)
  • Share receiving full coating system: 110 % (raised for this scenario; the documented default is 100)
  • Fixed booth and prep cost: 1,200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total coating cost = pumps to coat x coating cost per pump x share receiving full coating system + fixed booth and prep cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 10,440 $ for total coating cost per pump cost, the number this scenario is built around.
  • At this operating point the engine returns 174 $ / piece for coating cost per pump cost per unit.
  • At this operating point the engine returns 9,240 $ for variable coating cost per pump cost.
  • At this operating point the engine returns 1,200 $ for fixed coating cost per pump adder.

How this compares with the baseline

  • Against the tool's baseline example, where share receiving full coating system sits at 100% and the headline result is 9,600 $, this scenario comes in 8.75% above the baseline at 10,440 $.
  • It computes total coating cost as quantity times per-pump cost times the full-system share, plus fixed booth and prep, then divides to a per-pump figure. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total coating cost per pump cost: 10,440 $ (headline result)
  • Coating cost per pump cost per unit: 174 $ / piece
  • Variable coating cost per pump cost: 9,240 $
  • Fixed coating cost per pump adder: 1,200 $
