Frequently Asked Questions
The WN series is designed with wide impeller passages that can continuously pump gravel or high-plastic clay with a maximum allowable particle size of up to 350mm without clogging.
Wet parts are primarily constructed from high-wear-resistant high chrome alloy. Depending on the application, we also provide stainless steel or duplex alloys for corrosive environments like saltwater.
The double casing design allows the pump to continue operating even when the volute liner is almost worn down, guaranteeing no leakage and extending the time between maintenance intervals.
Yes, by changing the impeller diameter or adjusting the impeller rotating speed, you can easily change the discharge flow rate to adapt to changes in pipeline distance.
The minimum NPSH is 4 meters, which ensures excellent suction capabilities, enabling deeper dredging and higher allowable suction densities.
The WN pump features a front uninstallation construction, meaning parts can be removed from the front without dismantling the entire piping system. Special tools are provided to make the process fast and convenient.
