    • The invention relates to a hand-prosthetic with a plurality of displaceable digit members. A hydraulic circuit is arranged for displacing the digit members with a first pump, the first pump being arranged for low pressure, high volume operation, and a second pump, the second pump being arranged for high pressure, low volume pump operation as compared to said first pump. A decoupling device decouples the first pump from the hydraulic circuit during a closing operation of the hand-prosthetic. The disclosed hand-prosthetic may be fast, robust, have a high gripping force, uses only the volume of the natural hand and has an acceptable weight, for instance less than 450 gram. In short the present invention may enable a relatively small building volume, high power/weight ratio and economic energy consumption.
