Series overview
D and DG are horizontal multistage centrifugal pumps built to JB/T1051 with a modern hydraulic profile. The segmental stage construction produces heads from 55 to 684 m from a comparatively small floor footprint.
The D type handles clean water up to 80 °C for mine drainage and plant or city water supply; DG is intended for small boiler feed and similar hot-water duty up to 105 °C.
Design features
- Segmental multistage construction for high heads in a compact body
- D for mine drainage and plant or city water supply up to 80 °C
- DG for small boiler feed and hot water up to 105 °C
- Handles clean water with impurities below 1% and particles below 0.1 mm
