Pump Test Stand Capacity at 99% expected test stand uptime: a worked example

This scenario runs the pump test stand capacity calculation on the strong side: 99% expected test stand uptime, with every other input held at its documented default. Use it when pump test stand capacity in water, wastewater and pump systems manufacturing is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Pumps tested per stand cycle: 4 units / cycle (unchanged)
  • Available test stand cycles: 480 cycles (unchanged)
  • Expected test stand uptime: 99 % (raised for this scenario; the documented default is 90)
  • Expected test first-pass yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross pump test stand capacity = pump test stand capacity output per cycle × available pump test stand capacity cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good pump test stand capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross pump test stand capacity.
  • At this operating point the engine returns 19.2 units for pump test stand capacity downtime loss.
  • At this operating point the engine returns 57.02 units for pump test stand capacity yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected test stand uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • Use it to check whether the test stand keeps up with assembly, or to size the number of stands needed for a target output. 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

  • Good pump test stand capacity: 1,844 units (headline result)
  • Gross pump test stand capacity: 1,920 units
  • Pump test stand capacity downtime loss: 19.2 units
  • Pump test stand capacity yield loss: 57.02 units
