Hydraulic Pump Flow with hydraulic pump flow input load of 250 units: a worked example
What does the result look like when hydraulic pump flow input load reaches 250 units? The full calculation is worked below with real intermediate numbers. Use it when hydraulic pump flow in hydraulic, pneumatic and fluid power systems is being sized against an asset rating.
The inputs for this scenario
- Hydraulic Pump Flow input load: 250 units (raised for this scenario; the documented default is 100)
- Hydraulic Pump Flow load factor: 1.2 x (unchanged)
- Hydraulic Pump Flow operating time: 8 hr (unchanged)
Working through the calculation
- Applying the documented formula (Hydraulic Pump Flow load = input load × load factor) to the inputs above produces each figure below.
- At this operating point the engine returns 300 units for total load, the number this scenario is built around.
- At this operating point the engine returns 37.5 units / hr for hourly equivalent.
- At this operating point the engine returns 250 units for input load.
- At this operating point the engine returns 1.2 x for load factor.
How this compares with the baseline
- Against the tool's baseline example, where hydraulic pump flow input load sits at 100 units and the headline result is 120 units, this scenario comes in 150% above the baseline at 300 units.
- A figure at this level is achievable when hydraulic pump flow input load is genuinely sustained, not just peaked for a shift. It uses a single flat load factor and does not model pressure spikes, viscosity drift with temperature, or volumetric efficiency loss as a pump wears.
Results at a glance
- Total load: 300 units (headline result)
