    Hello, I am assuming a new topic because I could not find a similar one.
    I have already read that the 5.5 kW motor will pull the pump to a maximum of 12 cm3 so that it gives 190 bar

    Because I have a similar question to smart heads, how much will the 7.5kw motor pull
    I would like to choose a safe pump for it so that the pressure oscillates around 190 bar
    In the days I will give which actuator it should work with

    Would a 26/10 cm3 pump be ok!?
    I presume that section 26 for a straight pine and other trees with a 7.5kw engine will do well, and section 10 will be hellishly strong with such an engine, I will add that the pump I was looking at can easily work at 190-200 bar because the maximum continuous is at 250bar.

    I have to think how to drive 1: 1 two separate pumps because 2-section pumps are hellishly expensive. When I come up with it, I will optimize the costs.

    Maybe 10 by force
    And nsz 32 for speed
    Both set to 200bar !?
    Will it cope with 7.5kw

    And the simple option is 7.5kw plus 18-20cm3 pump and work at 190bar.

    Formula for the power requirement for a hydraulic pump

    Pan = pxQ / 600x nges = (kW)

    P = pressure bar
    Q = pump capacity liter / min
    Efficiency nges = 0.8-0.85

    Example
    P = 130bar
    Q = 36 l / min
    Efficiency = 0.8

    After substituting in the formula for an example hydraulic pump, we need 9.75 kW

    I ironed this pattern and I do not get 9 for China, with a hook for the data provided by a friend !!

    What will come with a pump for 190b pressure and 7.5kw motor !?

    we calculate the power demand assuming that the pump has a capacity of 36 liters per minute at a pressure of 130 bar

    130bar X36 liters gives us 4680 this result divided by (600x0.8) = 480
    4680 divided by 480 gives us 9.75 kW
