Single-flow propulsion unit (pump) for watercraft is a high-performance, single-flow water-based propulsion system, designed for pushing all types of marine vessels—including the largest. This technological breakthrough in maritime transport combines exceptional efficiency with high adaptability.
With flow rates up to 10,000 m³/min at 1,000 RPM, it delivers unmatched propulsion performance with minimal energy loss. Engineered for robust operation in all conditions, it includes an anti-jamming system that allows safe and reliable operation even in waters containing larger particles (up to Ø10 cm). A separate filtration unit is required to prevent larger debris from entering the pump.
It is ideal for tankers, container ships, cruise liners, and other large-scale vessels where reliability and thrust performance are mission-critical.
Single-flow propulsion unit (pump) for watercraft is engineered for use in maritime, river, and lake transport, offering exceptional power, durability, and system resilience.
Typical applications include:
This high-performance propulsion unit is the result of years of development and engineering expertise. It is designed to deliver maximum water throughput, optimized energy use, and minimal energy loss.
The unit body, 2,776 mm wide and 6,160 mm in diameter, is compact and built for seamless integration into a vessel's hull. This revolutionary innovation in marine propulsion ensures continuous operation, even in harsh sea conditions.
During extended periods of vessel inactivity or winter storage, full preservation of the propulsion system is required. For shorter downtime, the system should be flushed and cleaned with fresh water.
