The Efaflu NNJ HT High Temperature Pump is a robust centrifugal pump specifically engineered for handling high-temperature fluids in demanding industrial environments. Manufactured according to EN733 (DIN24255) standards, this pump ensures reliable and efficient operation under extreme thermal conditions.
Equipped with a closed radial impeller featuring dorsal fins for axial balance, the NNJ HT delivers stable hydraulic performance while minimizing wear. Its construction materials are carefully selected to withstand high temperatures, making it ideal for thermal oil circulation, boiler systems, and industrial heating processes.
With advanced sealing systems such as Car/SiC/AFLAS and high-grade materials like EN-GLS cast iron and AISI 420 steel, the pump guarantees durability, safety, and long service life even in continuous high-temperature operations.
