- Pump diameter：80、100、125、150、200、250mm
Applications:
- Widely used in mining,factories and city water supply and drainage.
- Suitable to pump clean water and fluids have close physical and chemical characters of water,or fluids like hot water,oils,corrosive material and particles.
Structure Features:
- The pump set mainly consists of bearing housing,inlet and out section,middle section,guide vanes.
- The pump inlet is horizontal and outlet is vertical;The balance hose on the inlet is connected back to the water inlet side.
- Between bearings structure.The rotary part consists of shaft,impellers and a balance disk.
- The gaps between pump inlet section,middle section and outlet section are smeared by molybdenum disulfide compound calcium-based lubricating grease as the sealings. The gaps of rotary part and static part are sealed seal rings,guide vane sleeve and packing.
- Standard shaft sealing is packing,can be customized as mechanical seal.
