Estimate a pump operating point or prepare a replacement inquiry. Your entries stay in this tab.

RENOWELL · A

Hydraulic workbench

Estimate flow, power and steady shaft load, then compare two operating points.

Efficiency varies with operating conditions; leave it blank if unknown. Assumptions are not test results. Enter the required flow at the pump outlet, with circuit losses included only where assessed by the equipment engineer.

Missing / unconfirmed: Displacement · Actual pump-shaft speed

Use these estimates for initial discussion. Confirm model ratings, inlet conditions, fluid compatibility, starting loads and motor thermal limits with Renowell and the equipment engineer before selection or installation.

Use pump outlet pressure minus inlet pressure, at the same operating point. Load pressure elsewhere in the circuit is not necessarily this difference.

Q₀ = Dn/1000 · Q = Q₀ηv · Ph = ΔpQ/600 · Ps = Ph/(ηvηm) · T = ΔpD/(20πηm). D in cm³/rev, n in rpm, Δp in bar, Q in L/min.

Calculation scope: displacement ≤ 10,000 cm³/rev, flow ≤ 30,000 L/min, shaft speed ≤ 30,000 rpm and pressure difference ≤ 1,000 bar. These are software scope limits, not permissible pump operating limits. No universal design margin is applied.
