■Flow rate: Q=3～846m3/h
■Total head: H=50～1450m
■Speed: n=1450rpm/2950rpm
■S.g.: γ ≤1.15
■Temperature: T=--20～160℃
■Pump diameter: 40～350mm
■Advanced hydraulic models with high efficiency and wide performance range.
■Smooth operation and low noise.
■Both packing seal and mechanical seal are available.
■Completely sealed shaft which is non-contact with fluid.
■The pump material can be changed to pump corrosive fluids. D(F) stands for a pump which is suitable for corrosive fluids, but its performance and is totally the same to D series.
■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.
