How the Pump Works

The triplex plunger system uses three ceramic plungers to create a steady, low-pulsation water flow. Stainless steel valves withstand repeated pressure cycles, and the nickel-plated brass head resists corrosion in harsh environments.

The gearbox reduces motor/engine input speed to 1,750 RPM, minimizing vibration and heat. Oversized bearings distribute load evenly, extending service intervals. The sight glass and vented dipstick make oil checks and maintenance fast and simple.
