Diesel multi-stage fire-fighting pump

■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.
