    AI Overview
    EN733 compliant end-suction pumps with low-noise features are designed for quiet operation in residential, commercial, and industrial water applications, often using optimized hydraulics and over-sized bearings to reduce vibration and noise below
    65
    dB
    . These centrifugal pumps, also known as DIN 24255, offer high efficiency and reliable performance for water supply and HVAC systems. 
    Key features of low-noise EN733 pumps: 
    • Reduced Noise & Vibration: Utilizes heavy-duty construction, specialized bearings, and balanced impellers for quieter performance.
    • Operational Standards: Compliant with EN733 (DIN 24255) standards for dimensions and performance.
    • Low NPSH: Designed with a suction profile that minimizes cavitation, contributing to quieter operation.
    • Applications: Ideal for HVAC, water boosting, and circulation in noise-sensitive environments.
    • Materials: Frequently available in cast iron, bronze, or stainless steel for durability. 
    Popular options include the Sulzer SES/SKS range for heavy-duty, low-noise performance, or specialized models from Eifel Pump designed for efficiency.
