The SMVD Multistage Vertical Donut Pump is a high-pressure pumping solution engineered specifically for demanding applications such as Reverse Osmosis (RO), seawater desalination, and wastewater treatment. Its innovative vertical multistage design combines high performance with operational efficiency and exceptional reliability.


  • High Pressure and Precision Flow Control: Engineered to generate pressures ranging from 16 to 70 Bar and achieve heads up to 400 meters, this pump is ideal for low-flow, high-pressure duties essential for RO and desalination processes. It efficiently handles flow rates from 0 to 300 m³/h, ensuring precise delivery for sensitive applications.

  • Compact, Space-Saving Design: The pump's vertical configuration results in a significantly smaller footprint compared to traditional horizontal pumps. This design is optimal for installations where space is limited, allowing for a more flexible plant layout.

  • Unmatched Piping Flexibility: A standout feature is the adjustable suction and discharge flanges, which can be oriented to 0°, 90°, 180°, or 270° as required. This provides immense flexibility for pipeline integration, simplifying the installation process and adapting to complex site configurations.

  • Robust and Efficient Performance: Utilizing multiple impellers stacked in series, the pump incrementally builds pressure to meet specific head requirements. This design ensures high hydraulic efficiency and reliable operation, contributing to lower lifetime costs. The pump is built for durability in challenging environments, including the handling of corrosive and abrasive fluids in chemical and zero-liquid-discharge (ZLD) applications.

  • Ease of Maintenance: Designed with serviceability in mind, the pump's construction allows for easier access to internal components, reducing downtime and simplifying maintenance procedures.
