Hydraulics calculator – calculate hydraulicsThe use of liquids to transmit force and energy.
Measurements and units used
|Geometr. displacement volumeThe volume of liquid in cm³ in a pump or motor displaced by the upward stroke or other cycle during a rotation of the drive shaft. per rotation||Vg||cm3|
|Total efficiency||ηt||Standard value ca. 0,85|
|Mechanical hydraulicThe use of liquids to transmit force and energy. efficiency||ηmh||Standard value ca. 0,85|
|Volume flow rate||qv||L/min|
|Volumetric efficiency||ηv||Standard value ca. 0,9|
|Gear pump diameter||D||cm|
|Gear pump length||L||cm|
|Gear pump gear width||W||cm|
qv = volume flow rate in in L/min
Vg = geometric displacement volume cm³/U
n = rotation speed in min-1
T = torque in Nm
∆p = differential pressure in bar
P = power in kW
Calculate gear pump conveyed volume
D = Gear pump diameter in cm
L = Length of bore in pump casing in cm
W = Gear pump width in 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.
