Introduction:
The Depon D Series multistage water pump is a highly efficient and reliable system designed for high-pressure applications. It can handle both hot and cold water and is commonly used as a booster pump in high-rise buildings, fire protection systems, boiler feedwater, cooling systems, and various irrigation projects.
The D series includes several types, such as the D, DG, DM, DF, and DY models, each tailored to specific fluid characteristics and operating conditions. For example, the D pump is ideal for clean water without solids or liquids similar to water with temperatures up to 80°C. The DG model is suitable for boiler feedwater and heating systems, while the DM model handles slightly contaminated water with particles up to 1.5%. The DF and DY models are designed for corrosive liquids and oil-based fluids respectively.
- Horizontal shaft design
- Horizontal split casing for easy maintenance
- Suction centrifugal type
- Closed impeller for efficiency
- Available in multiple materials including cast iron, stainless steel, and high chrome
- Mechanical or packing seals for leakage prevention
- Customizable color options
- Multiple drive options (electric motor or diesel engine)
- Wide voltage range (220V, 380V, 410V, 460V, and high voltage)
- Frequency options (50Hz or 60Hz)
