How the Pump Works

The STP-SS2050N is a high-performance triplex plunger pump. Three precision ceramic plungers compress water through stainless steel inlet and discharge valves to generate up to 7250 PSI of consistent pressure.

Low-Speed 1450 RPM Operation

• Lower vibration and heat generation
• Reduced internal wear for extended service life
• Superior efficiency for continuous-use environments

Bronze connecting rods and oversized bearings provide smooth mechanical action, while dual high-pressure seals maintain leak-free performance under extreme duty cycles.
