1.The structure of this ZJS series gravel pump is mainly single-casing and horizontal. The outlet direction can be positioned 360° easy to install.
2. Shaft Components adopt cylinder structure, which is convenient to adjust the gap between impeller and front wearing plate. The shaft uses grease lubrication.
3.Shaft Seal: expeller drive seal, packing seal, and Mechanical seal.
4.Broad Flow Passage & Good Anti-Cavitation Property & Highly Efficient Wear Resistance.
5.Driving Method: V Belt Drive, Elastic Shaft Coupling Transmission, Gear Box Drive, Fluid Coupling Transmission, Variable Frequency Drive Device and Thyristor Speed Control.
6.The wet parts are made of Ni-hard and high-chrome wear-resistant alloys with good anti-corrosive property.
7.Variable speeds and modals to ensure smooth operation. Additionally, Long service life and high operation efficiency offer reliable performance in a tough operating environment.
2.Applications of the Single Casing Pump
The mining gravel pump is used for river course, reservoir desalting, coastal reclamation, stretching, deep-sea mining and tailing acquisition etc.
