Key Features
WHY THE MODEL 300
3000 PSI Rating
Step up from the 1500 PSI Model 150 to 3000 PSI service using the same proven hammer cap design — no change in connection configuration or installation procedure required.
Blow-Out Proof Ram Screw
Same blow-out proof ram screw design as the Model 150. Prevents ram screw ejection under pressure — a critical feature at 3000 PSI service.
Carbon Steel Body
Carbon steel construction replaces the ductile iron of the Model 150 — providing the material strength needed for 3000 PSI service in a compact 9-½" height.
Reinforced Ram Block
Same reinforced ram block as Model 150. Reduces rubber extrusion at the higher 3000 PSI working pressure — extending ram service life.
