Hydraulic pump capacity

Hydraulic pump capacity can be estimated in Imperial units as

q = 0.26 A s / t                                         (1)

where

q = pump output capacity (gpm)

A = area of cylinder (in2)

s = piston stroke (in)

t = required time for full stroke (s)

  • 1 gpm (US) =6.30888x10-5 m3/s = 0.227 m3/h = 0.06309 dm3(litre)/s = 2.228x10-3 ft3/s = 0.1337 ft3/min = 0.8327 gpm (UK)
  • 1 in (inch) = 25.4 mm = 2.54 cm = 0.0254 m = 0.08333 ft
  • 1 in2 = 6.452 cm2 = 6.452x10-4 m2 = 6.944x10-3 ft2

Hydraulic pump capacity can be estimated in Metric units as

q = 10-6 A s / t                                         (2)

where

q = pump output capacity (l/s)

A = area of cylinder (mm2)

s = piston stroke (mm)

t = required time for full stroke (s)

Required pump output for hydraulic cylinders ranging 1 - 6 1/2 inches are indicated below. Multiply pump capacity with stroke length (in).

Hydraulic pumps - output capacity vs. cylinder diameter graph

Example - Required Pump Capacity

A 3" hydraulic cylinder with cylinder area 7.065 in2 makes a 30 inches stroke in 3 seconds. The required pump capacity can be calculated

 q = 0.26 (7.065 in2) (30 in) / (3 s)

    = 18.4 gpm
