The Ds (DK) Two-Stage Single Suction Split Case Pump is a modern, high-performance solution designed for a wide range of industrial applications. Developed through years of research and incorporating advanced foreign technology, this pump serves as an efficient alternative to traditional multi-stage pumps. It is suitable for clean water, liquids with small amounts of solid particles, and even mildly corrosive fluids. Common applications include high-rise building water supply systems, industrial boilers, fire protection, mine drainage, chemical processing, and various industrial water systems.
Key technical specifications of the DS pump include:
- **Pump Outlet Diameter (Dn):** 80–300 mm
- **Capacity (Q):** 100–1000 m³/h
- **Head (H):** 160–320 m
- **Temperature Range (T):** -20°C to 150°C
- **Solid Content:** Less than 80 mg/L
- **Working Pressure:** Less than 4 MPa
For example, the model **100DS-150X2A** indicates:
- **100:** Outlet diameter in millimeters
- **DS:** Two-stage split case pump
- **150:** Head per stage in meters
- **2:** Number of stages
- **A:** Impeller outer diameter adjustment (maximum without marking)
**Technical Advantages:**
1. **Axial Force Balance:** The two impellers are arranged back-to-back, which automatically balances axial forces. This eliminates the need for a balance disc, increasing reliability and reducing maintenance issues, especially when dealing with variable speeds or viscous fluids.
2. **Short Bearing Span:** A shorter bearing span enhances shaft rigidity, resulting in smoother and quieter operation. This makes it ideal for environments where noise control is important.
3. **Efficient Hydraulic Design:** The pump features an advanced hydraulic model that offers higher efficiency compared to similar multi-stage pumps, leading to energy savings and improved environmental performance.
4. **Easy Maintenance:** With a horizontal split casing and suction inlet and outlet located at the lower part of the pump, maintenance can be performed without removing the motor or piping, significantly reducing downtime and maintenance costs.
The Ds (DK) series is available in multiple configurations and is widely used across industries due to its durability, efficiency, and ease of use. For more details, you can view the product images below.
