CFM56-3 engines are part of the best-selling CFM56 engine family, which is produced by CFM International (CFM), a 50/50 joint company between Snecma Moteurs (Safran Group) and General Electric Company.
The engine was part of the original installation on a new Boeing 737-500 delivered to Hapag-Lloyd in December 1990; Malev has been leasing the aircraft since 1999. During its in-service life, the engine has undergone routine inspections but has remained trouble free. Malev plans to remove the engine for overhaul in September, so the ultimate record will be established at that time.
That is definitely impressive, but no doubt it had a big assist from the rather sizeable derate the CFM56-3 got when installed on a 737-500. IIRC Max takeoff on the 737-500 was less than max climb on a -400.
