Dredger pumps

Dredger pumps

In order to connect the main drive to a dredger pump, we offer hydraulically actuated clutches between the main drive and the gear box. This constellation allows dynamically acceleration of the dredger pump by our engagement clutch. Due to our thermal calculations a safe function is guaranteed at any time.

Hydraulical clutch | Series 002/021/202

Based on our friction linings, which have been tried and trusted for many years in the marine sector, clutches in this series reconcile high torque and thermal absorption rates as well as a favorable outer diameter. A high shaft diameter can also be used.

Due to their broad power spectrum, smaller sizes can be achieved with corresponding weight and cost benefits, especially in higher torque ranges. The optimized outer diameter makes shorter distances between axles possible, and in this way offers clear savings potential in the gearbox.

The hydraulic multi-plate clutch impresses with its comprehensive service friendliness. The plate pack, which is wear-free under the specified conditions, can be accessed from either side depending on the model, and ensures an easy, safe, and swift replacement of the plate pack. The special design also ensures that other components cannot fall out during replacement.

The Ortlinghaus muti-plate clutches safely accelerate even large propellers and generators. This optimal further development of our tried-and-tested technology sets today’s industry standards.

Torque: 22,000 - 450,000 Nm Rotations per minute: 9,800 - 350 min-1 Outside diameter:90 - 1,200 mm Bore diameter:35 - 500 mm Length:64 - 755 mm

Wet-running sinter-lining plates

For dry- and wet-running clutches and brakes, Ortlinghaus is able to provide a very comprehensive range of plates. The plates and the friction surface are important functional elements in every clutch and brake, and have been developed in many different ways since the early days of clutches and brakes. The choice of friction system depends on the application: in general, one plate with friction material works together with a counterplate of steel or cast iron. The inner and outer plates are mounted with the other drive components by lugs and slots, and the spline is in accordance with DIN 867 and DIN 5480 as well as other standards. In addition, holes in the plate for studs and special shapes in accordance with customer requirements are available.

Combined with a multi-plate clutch or brake, these plates come in a multitude of different dimensions, friction combinations, and surface patterns.
