Hydraulic pumps

Hydraulic pumps are also one of the key elements in generating pressure in a tail lift system. They can be internal or external to the oil tank. In some cases they are connected directly to the electric motor that transfers their movement or are fixed to an aluminum collector, on the opposite side of which the electric motor is obviously fixed. In this second case, the motion is transferred through a motor-pump connection joint. To allow the pump to work correctly, it must be ensured that the direction of rotation is opposite to that of the motor to which it is connected, since the motor or the pump is evaluated as the direction of rotation, both looking at the shaft. The pumps are all geared, the thing that most differentiates them is the displacement measured in ccm or liters per minute, the right (clockwise) or left (counterclockwise) rotation and the shape of the end of the shaft that defines the type of connection.
