D Series Horizontal Multistage Centrifugal Pump
D-series horizontal multi-stage centrifugal pump is produced from national recommend hydraulic model, allowing our pump a high efficiency, energy saving, high adaptability, sound and stable operation, low noise, long service life, easy maintenance and so on.
D-series horizontal multi-stage centrifugal pump is quite suitable for the transportation of clear water (with zero solid particles or suspended substances), or other liquids with similar physical and chemical properties as those of pure water. Meanwhile, when changing pump’s material (or that of overflow parts), sealing method, and adding an extra cooling system, the centrifugal pump could also be used to transfer hot water, oils, as well as corrosive or impure liquids.
