Sulzer has introduced a closed impeller to its Ahlstar A single-stage pump range, offering enhanced performance and improved efficiency.
AHLSTAR is a series of end-suction single-stage centrifugal pumps designed to work with all types of liquids in demanding industrial applications.
Sulzer’s Ahlstar A process pumps are available with six different impellers, each designed for specific industrial applications. Closed impellers are commonly used in water processes due to their high efficiency and good run ability. Also, a closed impeller offers a reliable option when processing flammable or toxic liquids, for instance in the chemical process industry.
The closed impeller is an addition to Ahlstar A end-suction single-stage pumps and can use the same mechanical seals and bearing units as other pumps in the series. Due to the modular construction, the need for spare parts is minimized. The pumps are available in various sizes and materials, including ductile iron, duplex stainless steel, and super duplex.
