Cryogenic Pump Energy Load with cryogenic pump connected motor load of 6 kW: a worked example

Suppose cryogenic pump connected motor load falls to 6 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate energy cost for a cryogenic transfer or circulation pump from motor load, runtime, power rate, and liquid moved.

The inputs for this scenario

  • Cryogenic pump connected motor load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Pump runtime for transfer period: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Cryogenic liquid moved: 1,000 gal or kg (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Pump energy used = cryogenic pump connected motor load × pump runtime.
  • Pump energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Cryogenic pump energy cost works out to 5.76 $ at these inputs.
  • Pump energy cost per liquid unit works out to 0.01 $ / piece at these inputs.
  • Hourly pump energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cryogenic pump connected motor load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 50% below the baseline at 48 kWh.
  • It computes the energy a cryogenic pump uses (motor load times runtime), the cost of that energy at your electricity rate, and the cost spread across the liquid volume moved. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
