The Enviroguard FSE and PSE seals are a face type seal for high performance applications. Available in both fully split (FSE) and partially-split (PSE) designs with an elastomeric body and Silicon Carbide interfaces.
The FSE and PSE seals are particularly suitable for high speed vessels, offshore supply vessels and other high powered vessels such as tugs and trawlers.
The FSE and PSE seals will accept misalignment, vibration and large axial movements. For applications with open sterntubes the inboard seal an emergency seal for safety, survey and maintenance purposes. The Enviroguard FSE can be fitted and serviced without removing the shaft, thus reducing the installation time to a minimum. The Enviroguard PSE features split spares meaning the seal can be serviced without removing the shaft.
Worn shafts and lip seal liners, leaking glands (stuffing box), and continuous maintenance are a thing of the past. The simplicity of the design provides maximum sealing capability. Reliability and hence long service intervals are achieved by the design of the elastomeric body and the choice of interface materials.
Performance is achieved by statically mounting the elastomeric body. Maintenance is reduced due to high abrasion resistance, no galvanic corrosion of interfaces, absence of shaft liner in way of seal and low sensitivity to misalignment and vibration which together give low through life cost.
The Enviroguard FSE and PSE seals cover shaft diameters ranging from 70mm to 450mm and with a compact build length it suit most stern frame designs.
