Municipal Engineering

Vertical axial pumps are the core part of municipal water supply and drainage system due to their features of large flow rate and less maintenance requirements.

Agricultural Irrigation

Ideal for lifting water from rivers, canals, or reservoirs to irrigate large farmlands, as it can handle the high flow rates required.

Flood Control and Drainage

Widely used in pumping stations to quickly move massive amounts of water from flooded areas (cities, agricultural fields) to rivers or seas.

Industrial Circulation

Commonly used in power plants, refineries, and large factories to circulate cooling water through condensers and cooling systems.

Water Transfer Projects

Essential in large-scale aqueducts or cross-basin water transfer schemes where water needs to be lifted only a short height but over massive volumes.

Shipbuilding Drainage

The vertical axial flow pumps serve as the dry dock pumps in shipbuilding plants to evacuate the large a mount of water from the dock during the manufacturing and repairing process of ships.
