Quick Tips to Calculate Pressure and Flow Requirements

  1. You’ll need the size and velocity of the actuators.
  2. Be sure to factor efficiency in your calculations.

Calculate Pressure and Flow Requirments

Before you select a pump for your HPU, you must calculate your pressure and flow requirements. To calculate flow required by your hydraulic pump, you must know the size and velocity of the actuators it will power. It is important to calculate the maximum flow required during simultaneous actuator operation, such as a motor and cylinder working in tandem. You must always factor efficiency in your calculations, so as not to lead to disappointment during commissioning.
