Controllable-Pitch Propeller (CPP) · Shaft Line & Propulsion
Controllable pitch propellers are essential components in modern marine vessels, enabling precise control over thrust and fuel efficiency. The Wärtsilä LIPS E-Hub 4E2085 is designed to meet the demanding requirements of various ship types. This propeller features a streamlined hub contour, which reduces fuel consumption and minimizes cavitation, making it well-suited for high ship speeds. The non-split hub casting with a loose hub cover provides extra rigidity and a robust construction, ensuring low and easy maintenance. The LIPS E-Hub 4E2085 utilizes steel blade carriers to further reduce fuel consumption. This design, with its lower propeller/hub diameter ratio and higher propeller efficiency, contributes to overall operational cost savings. Double oil pipes are integrated into the system, preventing water intrusion into the hub in case of sterntube sealing leakage. This ensures safe operation and avoids interference with the sterntube lubrication system. The LIPS E-Hub 4E2085 offers a range of hub diameters from 1000 mm to 2085 mm, allowing for customization based on specific vessel requirements.
