Manufacturing ManeCraft Seals for over 15 years
Industrial Rubber are pleased to confirm that manufacture and assembly of ManeCraft kits will continue after Wartsil’as sale of the business. As the existing manufacturer, we have been supplying the kits for many years to Wartsila and are pleased to keep the range available for the future.
The Manecraft stern seal operates using two primary components: the stationary seat assembly and the rotating seal assembly, both moulded from chloroprene rubber.
The stationary seat incorporates a bronze ring that is chemically bonded to it. It is fastened onto the sterntube using two stainless clips, ensuring it remains stationary. The stationary seat also includes a red emergency sealing clip, which serves as a safety feature for emergency situations and is safeguarded by a tamper-proof tag.
The rotating seal assembly is clamped onto the shaft and compressed against the seat. As the shaft rotates, the seal assembly rotates with it. The sealing face of the seal assembly moves against the stationary bronze seat, benefiting from lubrication and cooling provided by the water inside the seal, assisted by a water flush system.
To prevent airlocks and maintain effective cooling of the seat, the flush system incorporates an air vent. This design feature ensures that if the boat is out of the water or taken ashore, no action is required upon relaunching.
ManeCraft seals are designed for easy installation and serve as direct replacements for traditional propeller shaft packed glands. They eliminate the need for packing, adjustments, or ongoing maintenance and prevent the formation of grooves on the shaft. Once installed, they only require a quick inspection along with other underwater hull fittings, such as sea cocks and hoses.
