This is a double core pull auxillary power pack manufactured by Rexroth. These power packs are used to provide a double core pull hydraulic circuit to a moulding process when not originally fitted to the machine. One of the most common uses of these power packs is when used with an all-electric moulding machine.
An all-electric machine wouldn’t have an hydraulic circuit available to be used with core pull and it would not have an oil cooler. Some manufacturers do offer this as option on all-electric machines but it is typically very expensive and is not often seen as a result.
This unit is completely self-sufficient with a 50 litre oil tank, integrated oil cooler and a proportionally controlled pump. The unit interfaces with the machine via a 16 pin plug, the interface required will be different from manufacturer to manufacturer.
