**What is a sand pump?**
The ZJS series sand dredging pump is a new type of single-stage, single-suction, cantilever horizontal centrifugal sludge pump developed by our company. It's specifically designed for river and sea dredging and damming operations. The wet parts, such as the casing, impeller, front liner, and rear liner, are made from high-hardness casting alloy iron with a hardness of at least 58HRC, ensuring excellent wear resistance and durability. This makes it ideal for harsh environments like dredging. **Key Features of the ZJS Sand Pump**
The ZJS pump is engineered for lightweight design, strong wear resistance, and superior dredging performance. It’s perfect for various construction projects, offering significant economic benefits. Here are some key advantages:
The 200ZJS–500ZJS models feature a single-casing design with mechanical or stuffing seals. They can be equipped with self-supporting brackets or pump-box assemblies. Lubrication options include grease or thin oil. For larger models like 600ZJSH–1000ZJSH, a double-casing design is used, featuring spiral sleeve L-shaped rubber seals with three L rings and a special threaded shaft sleeve. These models use forced thin oil lubrication, ensuring the liner operates until fully worn out without water ingress. **Main Components**
