HWN Series Dredge Pump China Factory and Leading Suppliers of Industrial Slurry Pumps
The HWN Series Dredge Pump is a high-performance industrial solution engineered for demanding dredging operations. Featuring a robust horizontal cantilever structure, these pumps are available in single-pump casing designs for models 200HWN to 500HWN and double-pump casing designs for larger models from 600HWN to 1200HWN. With versatile lubrication options including grease and oil, the series ensures seamless integration into various mechanical setups via built-in brackets or integrated gearboxes.
Designed for maximum efficiency in harsh environments, the HWN Series excels in suction capacity and digging depth, effectively handling high respirable concentrations. By optimizing impeller flow channels and performance curves, these pumps provide exceptional adaptability to displacement changes, allowing operators to fine-tune performance by adjusting pump speed or impeller diameters to meet specific site requirements.

Frequently Asked Questions
Q: What is the primary difference between the 200-500HWN and 600-1200HWN models?
The 200-500HWN models use a single pump casing, while the 600-1200HWN models employ a double pump casing to handle higher capacities and pressures.
Q: How does the HWN series handle highly abrasive materials?
Overflow parts such as the impeller and liner are made of strong anti-wear alloy cast iron with a hardness of at least 50HRC, combining impact resistance with high abrasion resistance.
Q: Can the pump’s performance be modified after installation?
Yes, a variety of performance outputs can be achieved by either changing the speed of the pump motor or altering the diameter of the impeller.
Q: What lubrication methods are supported for the HWN series?
Depending on the model and configuration, the pump supports either grease lubrication or oil lubrication to ensure optimal bearing protection.
Q: How does the pump minimize maintenance costs?
The product design ensures that the service life of various wear parts is matched, meaning they reach their replacement cycle at roughly the same time, reducing labor and downtime.
Q: What is the advantage of the HWN pump’s performance curve?
The performance curve drops sharply, which makes the mud pump significantly more adaptable to changes in displacement during dredging operations.
