The pump mounts via a 4-bolt SAE 4F17 flange and features a steel output shaft (yellow shaft protector cap installed), with port connections visible on the rear face — a larger inlet and smaller outlet consistent with the 1\/2 in NPT \/ 3\/4 in NPT porting typical of this Concentric 4F series frame. Constructed from durable cast iron for use in open-center hydraulic circuits on log splitters, dump trailers, snow plows, and light industrial power units, this unit ships new — other (complete with mounting gasket, hardware, and bilingual instruction sheet as shown), with an integral pressure-relief\/bypass valve (red-capped adjustment screw visible on the port face) for system protection.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct
