12239
The LEO ABK50(D) is a heavy-duty semi-open impeller centrifugal pump engineered for demanding applications where reliability and corrosion resistance are essential. Built from premium AISI 304 stainless steel throughout its pump body and shaft, this versatile unit excels in industrial and domestic sewage systems, food and beverage processing, agricultural operations, and raw water transfer from rivers and lakes. Its semi-open impeller design allows the pump to handle liquids containing light impurities and suspended solids up to 19mm in diameter without clogging or performance loss.
Constructed with robust stainless steel components and equipped with a copper-wound motor featuring built-in thermal protection, the ABK50(D) delivers dependable performance across a wide temperature range of -15 degC to +80 degC and accommodates pH levels from 5 to 9, making it ideal for mildly corrosive and health-critical applications. Its IPX4 enclosure rating and F-class insulation ensure durability in wet environments, while the pump operates at full head capacity without motor overload-a critical advantage for continuous industrial and municipal water transfer applications where efficiency and longevity matter most.
