How the RW15 Works

The RW15 uses a triplex plunger design to deliver smooth, consistent high-pressure output with reduced pulsation. Ceramic plungers withstand thermal and frictional stress during continuous-duty operation, while stainless steel valves ensure reliable sealing and long-term durability. The forged brass manifold provides corrosion resistance and structural strength needed for commercial environments.

Operating at 1,450 RPM, the RW15 balances efficiency and longevity by reducing heat buildup and mechanical stress. Its 24mm solid shaft allows easy integration with belt-drive systems, gas engines, and various commercial drive configurations, making it highly versatile for rebuilders and OEMs.
