The DS (DK) Two-Stage Single Suction Split Case Pump is a cutting-edge product developed after years of research, combining advanced foreign technology with our own innovations. It serves as a modern alternative to traditional multi-stage pumps. This pump is designed for clean water, liquids containing small amounts of solid particles, and corrosive fluids. It is widely used in high-rise building water supply systems, industrial boilers, fire protection, mine drainage, chemical industries, and various industrial water systems.
Key technical specifications include:
- Pump outlet diameter (Dn): 80–300 mm
- Flow rate (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 E.G 100DS-150X2A indicates:
- 100: Outlet diameter (mm)
- DS: Two-stage split case pump
- 150: Head per stage (m)
- 2: Number of stages
- A: Impeller outer diameter modification (maximum without marking)
Technical advantages:
1. The two-stage impellers are arranged back-to-back, automatically balancing axial forces. This eliminates the need for a balance disc, significantly improving reliability and reducing failure rates. It performs well under variable speeds and viscous liquid conditions.
2. With a short bearing span, the shaft rigidity is increased, ensuring smooth and quiet operation, making it ideal for noise-sensitive environments.
3. The pump features an excellent hydraulic design, offering higher efficiency compared to similar multi-stage pumps, resulting in energy savings and better environmental performance.
4. Its horizontal split casing design allows for easy maintenance. The suction and discharge ports are located at the lower part of the pump casing, eliminating the need to remove the motor or piping during maintenance, which reduces downtime and costs.
