This is a Universal Pump and Reciprocator model designed for professional use only. Part of the Dyna-Star Hydraulic system family. This appears to be a complete reciprocator model designation rather than an individual part. The page shows reciprocator parts that would be compatible with this model, including reciprocator assembly 239883, gaskets, o-rings, pins, and displacement pumps. Model 224751 is one of three weight variants of the Dyna-Star pump, with 224751 being the middle weight option at 37.5 lb. Sound pressure reading taken with pump operating at 66 cycles per minute per CAGI-PNEUROP, 1971.
