一、Features: 
1. The suction inlet of the pump is vertical downward, the outlet is horizontal, free vacuum start, single foundation installation, direct connection of the pump and motor, and small floor area
2. Smooth operation, safe and reliable, efficient energy saving and convenient start.
3. Optimized design with hydraulic model has superior performance and takes into full consideration the anti-wear and anti-cavitations performance of the impeller and guide blade, which greatly improves the service life of the impeller, guide blade and other parts
The impeller of the pump adopts balanced hole to balance axial force, and the cover plate of the impeller is provided with replaceable sealing ring to protect the impeller and guide blade. The shaft is connected by a coupling nut or a sleeve coupling; The number of riser can be increased or decreased according to the user's needs, and it can be adapted to different liquid depth. The impeller and the guide can be single or multistage, which can adapt to different head requirements.
