For pumps with semi-open impellers, it is crucial to minimize the gap between the front disk and the impeller to maintain the designed efficiency.
In the case of pumps for hard pumpable media, this gap increases over time due to the presence of abrasive particles. Using the SPIRAM AFD (Adjustable Front Disk) mechanism, this gap can be adjusted to an optimal value, ensuring the pump remains highly efficient.
The pump's efficiency is directly linked to energy savings, resulting in significant financial savings over the course of a year.
