Piston RodsThe piston rod incorporates the Grayloy longer-wearing surface to provide the best piston rod for your triplex or duplex pump.
Rod Clamp with Integral Spray SystemA cooling spray system is built into the clamp itself. The spray pipe is placed directly behind the piston. This volume provides an adequate spray to flush the liner and cool the piston.
This duplex piston gives excellent service in both oil and water base muds. The fail-safe fluid expanded lip is not damaged by high pressure and fast pump strokes.
High-quality Grayloy material is used on all duplex piston rods. This corrosion-resistant, high density and long-wearing surface results in fewer packing changes and longer life for gland bushings and junk rings.
