As with all Rexroth (Bosch Group) products, the quality is ensured in the name. The motor used in the power-pack is either 2.2KW, or 3KW and doesn't require a starting capacitor. This is due to a soft start valve built into the pump. When the power-pack is activated, the oil from the reservoir is pumped through the pump and back into the reservoir until the flow reaches 6 litres per minute. At this stage the motor is at full speed, so the soft start valve closes, and the ram begins to lift. This operation all happens in a matter of milliseconds, ensuring the motor is under minimal load (and torque), resulting in a longer lifespan for both motor and pump.
