Description
The Barmesa SOX3-50-2 is a 50 HP, 3-Phase, 230V end-suction centrifugal stainless steel pump. These pumps efficiently handle fluid transfer tasks in various industrial, commercial, and municipal environments. Constructed from stainless steel, they are ideal for applications requiring corrosion resistance and hygiene , such as water supply, chemical processing, food and be 1¼", 1½", 2", 2½" and 3" vertical flange 150 lb DIN MAX. LIQUID TEMPERATURE 248 °F (120 °C) MAX. WORKING PRESSURE 145 PSI (10.2 kg/cm²) BODY 304 stainless steel.
End-Suction Centrifugal Design — Industrial Standard
End-suction close-coupled design suits HVAC circulation, water supply, light industrial process, and pressure boosting applications. NEMA-standard motor frame for direct field motor replacement.
Back Pull-Out — Service Without Breaking Piping
Back pull-out design allows impeller, seal, and wear ring service without disconnecting suction or discharge piping — significantly reducing labor time and cost on permanently installed pumps.
Bronze and Cast Iron Construction Options
Available in bronze fitted, all-bronze, and all-iron construction to match your fluid chemistry and service requirements. Multiple seal material options cover water, HVAC, and light chemical applications.
Dynamically Balanced Impeller
Factory-balanced impeller to ISO G6.3 specification minimizes vibration — reducing bearing loads and extending service life on continuous HVAC and water supply duty applications.
Multiple HP Configurations
Available across a wide HP range within each series. All models share casing dimensions and spare parts — changing HP requires only a motor replacement, not repiping or a new pump body.
