The WAL51B-1005 or WAL51B1005 is a hydraulic pump, identified by the manufacturer code WAL51B15KPN2NO12N2N1. Gear-type hydraulic pumps work by drawing fluid in as the gears part on the inlet side, carrying it around the housing between the teeth and pushing it out as they mesh again, so flow rises with shaft speed. A pump that grinds, whines or knocks may be cavitating or have worn gears or bearings inside. Sold by Pro Gear and Transmission. Call us with your application and we will help confirm fit.
