qv = volume flow rate in in L/min

 Vg = cm3 n = min-1 ηv = (Standard value ca. 0.9)

 P = kW Δp = bar ηt = (Standard value ca. 0.85)

Vg = geometric displacement volume cm³/U

 qv = L/min n = min-1 ηv = (Standard value ca. 0.9)

 T = Nm Δp = bar ηmh = (Standard value ca. 0.85)

n = rotation speed in min-1

 qv = L/min Vg = cm3 ηv = (Standard value ca. 0.9)

 P = kW T = Nm

T = torque in Nm

 Vg = cm3 Δ = bar ηmh = (Standard value ca. 0.85)

∆p = differential pressure in bar

 T = Nm ηmh = (Standard value ca. 0.85) Vg = cm3

 P = kW qv = L/min ηt = (Standard value ca. 0.85)

P = power in kW

 T = Nm n = min-1

 qv = L/min Δp = bar ηt = (Standard value ca. 0.85)

Calculate gear pump conveyed volume

Conveyed volume calculation for a gear pumpThe oil volume enclosed in the gap between teeth is conveyed from the intake to the discharge side of the pump by the turning of the gear, displaced to the contact point of the wheel and forced into the pressure connection. (very accurate approximation)

 D = cm L = cm W = cm

Calculate hydraulics quickly...

HK Hydraulik GmbH offers all professionals and interested parties ready-made calculators for the most important hydraulic calculations.

Until now, to calculate the Volume flow rate or conveyed volume of a gear pump, technicians had to look up the formulas, pick up a calculator, enter the calculation according to the formula, and recalculate it again to check as a precaution. This could take a whole 15 minutes.

Now you just have to enter the values you know / have calculated / measured into the relevant calculator module, and you get your result straight away.

Please note: when we suggest standard values, this gives you a very close approximation that is good enough for general use. You can of course also enter the actual values instead of the standard values.

Our tip: bookmark this page on your workshop computer or smartphone. We are delighted if we can help you with our hydraulics calculator.
