The DY series multi-stage pumps are designed for the transfer of non-solid oily liquids and petroleum products within a temperature range of -20°C to 105°C. The wet parts can be made of cast iron, stainless steel, or as per customer requirements.
Nomenclature Explanation:
DY280-43x8(P)
- DY: Multi-stage centrifugal oil pump
- 280: Design flow rate of 280 m³/h
- 43: Single stage head of 43 meters
- 8: Number of stages is 8
- P: Self-balancing multi-stage pump
New Structural Design:
This design features a symmetrical arrangement of impellers in two opposite groups, which helps balance axial forces during operation. This eliminates the need for traditional balancing systems, reducing wear and improving efficiency.
High Efficiency:
Thanks to advanced hydraulic design, these pumps are highly efficient and energy-saving. The alignment of impellers and diffusers remains stable, ensuring consistent performance over time and reducing power consumption by up to 2-3% compared to traditional models.
High Stability:
With optimized impeller and diffuser configurations, this pump maintains high stability and efficiency even after long-term operation, making it ideal for industrial applications.
Reliable Mechanical Seal:
The absence of axial pulsation during start-up and shutdown reduces stress on the mechanical seal, significantly improving its reliability and lifespan.
Easy Maintenance:
Designed for quick assembly and disassembly, the pump allows for easy replacement of seals and bearings without removing the casing, saving time and effort during maintenance.
Low Maintenance Costs:
By minimizing vulnerable components and extending service life, the pump reduces overall maintenance frequency and costs, offering long-term value.
