This wear may vary depending on the operating parameters (temperature, pressure, speed, water conditions) and the installation/usage situation and may result in the failure of the above products/components, including their electrical/electronic circuits, at different times. Wear or wearing parts are all components subject to rotary or dynamic stress, including electronic components to which voltage is applied, including in particular: Gaskets (including mechanical seals), seal rings. Stuffing boxes. Bearings and shafts. Impellers and pump components. Thrust rings and wear rings. Wear rings / wear plates. Macerators. Condensers. Relays/contactors/switches. Electronic circuits, semiconductor components etc. Pumps and continuous-flow machines (such as submersible mixers and recirculation pumps) and their coated components (cataphoretic, 2K or Ceram coating) are subject to constant wear due to the abrasive content of the fluids. For this reason the coating of these units is also counted as a wearing part! We do not accept any liability for faults or defects arising from natural wear and tear.

The unit must be fully immersed in water during operation. General notes - ErP (ecological design-) directive The benchmark for most efficient water pumps is MEI.7 The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter. The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.
