Marine Seals

Marine Seals

A demanding industry and here at Vulcan we appreciate the challenges this volatile marine environment can inflict upon machinery within vessels, either out at sea, or in the docks undergoing repair and vital maintenance.

Vulcan have a long established range of direct replacement seal designs to suit all types of pumps and compressors associated with the marine and shipping industries. In all cases the Vulcan seals will resemble the original parts, while providing improved performance and quality benefits from our design and manufacturing policies. Vulcan seals fit directly into the original equipment without modification to either the pump, or the installation procedure.

Vulcan Type 9X - Improved Seal Performance by Design

The Vulcan Type 9X mechanical seals as an example are robust, general purpose, parallel spring, pusher type seals, designed to suit standard metric and imperial housing dimensions, that are commonly found in the marine industry. These are a direct replacement for John Crane®, Flexibox® Types R00, R10, R20 and R30 series, together with Pillar® US1, US2 and US3 series (CGU).

Featured below are the Standard 9X range, supplied with either solid or inserted rotary face, in a wide variety of face and elastomer materials. All types provide a positive drive to the rotary face, by a heavy duty spring, which is supplied either with left or right-hand wound springs, depending on whether clockwise or anti-clockwise shaft rotation.

Four versions are available and vary only by the method or providing the drive to the rotary seal face

Type 95 - Drives directly from shaft
Type 96 - Type 95 components with the addition of a split ring and washer for simple shaft abutment.
Type 97 - Type 95 components with addition of a grub screwed drive collar.
Type 98 - Heavy duty, single spring, pusher type seal, supplied with either solid or inserted rotary face, in a wide variety of face and elastomer materials. Seal is driven by a grubbed screwed collar , similar to the Type 97. The Type 98 design is unique compared to 95,96 and 97, as it is designed to suit different housing sizes and is supplied with a double ‘O’ ring stationary seat, as standard.
