The SFP 500-20 EH centrifugal fire pump is engineered for end suction applications, operating at 50/60 Hz with a top centerline discharge for optimal performance. It features a robust foot-supported casing and a back pullout design, which allows for easy maintenance without disturbing the piping system. The self-venting design ensures efficient operation by preventing air entrapment. This pump is equipped with an efficiently designed, dynamically balanced impeller to reduce vibration and noise, ensuring smooth operation. Its heavy-duty construction with thick walls enhances durability, and each unit undergoes rigorous hydrostatic and performance testing to guarantee reliability. The casing is available in cast iron or ductile iron, while the impeller can be made of bronze or duplex on request. The shaft is available in alloy steel, stainless steel, or duplex materials.
