Basically a “Separate” cooling method is advisable. If a “Return-Line” cooling method is used, a “by-pass” system is required, and in the case of incorrect installation, it may cause a cooler failure. In applying this method, one has to install a small pump, where the heated oil is circulated through the cooler and returns the oil back to the reservoir. This system has no pressure peaks within the hydraulic system. It will provide a safe & positive result. An economic coolant pump can be used in this “Separate” cooling system. In the case of a “Return-Line” cooling method being selected, please refer to your supplier for further assistance.
