Sulzer - High Pressure Axial Flow Pump (AH)

The High Pressure Axial Flow Pump (AH) is a loop reactor circulation pump engineered for very high pressure applications, particularly in the polyolefins industry. Designed for the continuous circulation of polyethylene and polypropylene slurry, this pump features a robust construction with a large shaft to minimize deflection and maximize seal life. It incorporates double or triple mechanical seal arrangements, API seal support systems, and a tilting pad thrust bearing with integrated heat exchanger for enhanced reliability. The pump is suitable for direct mounting or installation with a sprung baseplate to accommodate thermal expansion, ensuring long operational life and minimal maintenance in demanding process environments.
