Viking Gear Pump 2.5"

Viking (or "Roto-King") Series 4625 and KK4624/KK4625 are heavy-duty, internal gear pumps designed to handle highly abrasive liquids like inks, paints, resins, and starches. They utilize ultra-hard tungsten carbide idler pins and bushings to significantly extend wear life in tough industrial applications Key Specifications Series 4625 & 4624B: The 4624B Series is the updated successor to the classic 4625 line. Sizes KK4624 / KK4625: Denotes the specific pump displacement/frame size. Viscosity Range: 38 to 750,000 SSU (3 to 160,000 cSt). Maximum Pressure: Up to 150 PSI (10 Bar). Temperature Range: -60°F to 250°F (-50°C to 120°C). Design Features Hardened Wear Parts: Tungsten carbide idler pin and idler bushing to minimize friction and abrasive wear. Mechanical Seals: Behind-the-rotor abrasive liquid seal with a flush line to prevent premature seal wear. Thrust Control: Positive-lock thrust control for accurate axial positioning of the rotor and shaft. Adjustable End Clearance: Rotatable bearing housing design allows for simple end clearance adjustment to maintain pump efficiency as parts naturally wear down. IN STOCK
