During development of the next-generation pump series, particular emphasis was placed on reducing noise emission. The designers' goals were not to absorb noise, but to avoid producing it. State-of-the-art construction techniques led to a previously unknown level of noise reduction:

• Low pump speed
• No gearbox required
• Cambered impellers
• Noise decoupling thanks to elastic pump bearings

• Improved communications at the scene
• Pleasant working conditions
• Avoids health risk for firefighters
