Marine
Typical Applications
Cooling Water Pump
Cooling water pumps are large flow-rate, low- to medium-head units that operate at low rotational speed. Cooling water pumps are employed for marine and offshore industry, and it is basically divided into sea water cooling pump, and fresh water-cooling pump. It is a kind of popular engine room pump employed in vessels or ships.
Seal Type: U320N/43
| Media | Sea Water |
| RPM | 2900 |
| Temperature | 300 C |
| Pressure | 12 Bar |
Dredging Pump
A dredge pump is a horizontal centrifugal pump, it is designed to handle abrasive granular materials and solids of limited size in suspension. The dredge pump is designed to take in sediment, debris, and other harmful materials from the surface floor into a suction pipe, carrying the material to a discharge site through a pipeline. The pump must be able to handle common solid fragments of various sizes that are capable of passing through the pump, minimizing downtime required for cleaning.
Seal Type:U700N/130
| Media | Sea Water |
| RPM | 2750 |
| Temperature | 300 C |
| Pressure | 7 Bar |
Lubricating Oil Pump
Lubricating oil pumps are employed to supply oil to lubrication points, e.g., for plain bearings. In case of circulation, the lubricating oil pump takes in an amount of oil from a reservoir, forces it through the lubrication points and then feeds it back to the reservoir.
Seal Type: U700N/65
| Media | Lubricating Oil |
| RPM | 2750 |
| Temperature | 1600 C |
| Pressure | 6 Bar |
Gear Box
The Gearbox is a mechanical device mainly employed to increase the output torque or to change the speed (RPM) of a motor. The shaft of the motor is connected to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio.
Seal Type: ADKS/130
| Media | Oil |
| RPM | 150m/s |
| Temperature | 1200 C |
| Pressure | 20 Bar |
Marine
With automation in marine applications and the protection of our seas, the sealing technology is becoming increasingly important. Various different media need to be sealed in the tightest of spaces on board ships: the spectrum of applications in this sphere ranges from fuel supply, fire fighting facilities, bilge and ballast tank pumps right through to tubular stern seals, thru-bulkhead receptacles and flue gas ducts. Many of the seals used in such applications have to be seawater resistant, so in many cases are made from high-quality materials.
