AMT 2105-022-01 Stainless Steel Impeller, 1.90 HP
The AMT 2105-022-01 is the genuine stainless steel impeller for AMT’s 1.90 HP three-phase build, carried under the factory designation "Impeller XSS 1.90HP 3PH MBV". Stainless is the material of choice here for two reasons that work together: it resists corrosion in salt water, washdown chemicals and aggressive process liquids, and it keeps a crisp vane edge far longer than bronze or cast iron under abrasive flow.
Vane edge sharpness matters more than most people expect. The leading edge of each vane is where the liquid is picked up, and once that edge rounds off the impeller stops gripping cleanly — flow separates from the vane surface, turbulence increases, and a slice of the pump’s head disappears. The process is gradual and silent. A pump that has lost fifteen per cent of its output to rounded vanes sounds and looks exactly like one that has not.
Replace the impeller when the vanes are visibly thinned, when the shroud has worn through, when erosion has opened the running clearance, or when you find the pitted honeycomb texture that cavitation leaves on the vane backs. AMT matches impeller diameter and profile to the motor rating, so a 1.90 HP three-phase impeller is not interchangeable with one cut for a different horsepower even if it fits the shaft. Check your nameplate against the parts breakdown before ordering.
