D(DF) collection is a centrifugal pump of horizontal,single suction,multistage and sectional composition.It owns the attributes of large performance,vast functionality variety,smooth operation,reduced sounds,easy maintenance…D(DF) series was made to pump clear drinking water or fluids have close people of drinking water. Also,by changing pump wetted parts,it is capable to pump fluids like very hot water,oil,corrosive fluids and fluids particles.
- Flow rate:Q=20~540m3/h
- Total head:H=16~370m
- S.g.:γ ≤1.15
- Pump diameter:eighty,a hundred,one hundred twenty five,150,two hundred,250mm
- CZPT hydraulic models with high efficiency and wide performance range.
- Smooth operation and low noise.
- Both packing seal and mechanical seal are available.
- CZPTly 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 verticalThe 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 CZPT as mechanical seal.

- 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.
