ELECTRIC PODS & THRUSTERS, OUTBOARD ABRASION RESISTANT & ANTI-POLLUTION FACE TYPE SEALS
Wärtsilä Oceanguard - OFS3H-P
The Wärtsilä Oceanguard, OFS3H-P, is an oil lubricated outboard face type seal and offers anti-pollution and abrasion resistance capabilities. The Wärtsilä Oceanguard product range uses a unique design with a face type seal in the sea water and lip seals to operate in the stem tube oil.
The standard seal, OFS3H-P, contains a void space between the water and oil interfaces to provide a separation that enables monitor and draining. This prevents any contamination of the oil system with sea water and vice versa.
In certain thruster applications pressure compensation is included to comply with pressure pulsing through increased shaft movements.
