W&WW De-ragging Application
Gronwert expertise in de-ragging pump application with VFD, which removes clogs to protect the pump while reducing maintenance activities & costs.
Ensures the preservation of the maximum pump capacity by minimizing deposits on the impeller.
Clogged impellers in wastewater pumps can be a permanent and serious problem.
Over time, fibres and particles will build up on the impeller vanes, leading to poor efficiency and extensive wear of the pump.
Clogging reduces the capacity of the pump and risks blocking the pump, resulting in downtime for maintenance and ultimately a shorter lifetime expectancy.
De-ragging functionalities is built-in as standard, saving you the cost of an external, traditional deragger and greatly reducing maintenance expenses with the reactive and preventive pump feature.
