WESMAR Complete Hydraulic System Diagram A typical hydraulic system can operate WESMAR’s bow and stern thrusters, WESMAR stabilizer systems, WESMAR windlasses, WESMAR APU (get home) systems, winches, cranes, davits, hydraulic doors, hatches, passerrelles, ladders or steering gear. The design characteristics of the WESMAR custom hydraulic systems allow for the easy addition of other hydraulic functions at any time. WESMAR hydraulic systems come fully documented, including drawings both isometric and schematic, for all levels of hydraulic support in the field. All hydraulic systems are pre tested...

WESMAR Load Sense Central Hydraulic System WESMAR hydraulic packages are designed for superior long-term system life and performance. At the heart of the systems are precision-engineered distribution manifolds, which are virtually leak free, compact, and simple to upgrade should any hydraulic devices be added to the hydraulic continuous operation. Multiple manifold sections are integrated with a common pressure inlet and individual pressure outlets for connection to each hydraulic consumer. At system standby the load sense pump maintains a minimal system pressure of 300 - 400 psi (21-28 bar),...

WESMAR Design Considerations The correct hydraulic pump for the application depends on the Revolutions Per Minute (RPM) of the engine to which it is mated, be it a direct mount to the harmonic balancer, or through a transmission or generator Power Take Off (PTO). Hydraulic pumps are rated to provide a specific displacement for each revolution with pump efficiency de-rating the flow as RPM decreases. Highest demand fluid consumers - Bow and Stern Thrusters – are typically used when the engines are at idle while entering or leaving the slip. With a typical idle at 650 RPM and a 1:1 PTO to Engine...
