Manufactur standard Spiral Wound Gasket-CG for Naples Factories

Spiral wound gasket consists of “V-shape”(or”W-shape”)metal tape and nonmetal tape, which are overlapped each other and wound continuously.To fasten the metal tape,both its start point and end point are tack welded.

Feature

Wide Scope of acceptable working conditions. Can be used under high temperature, high pressure and ultra-low temperature or vacuum conditions. Change the combination of the gasket materials is to tackle the chemical corrosion problem of diverse media toward the gasket.

Not very rigid requirements to the surface precision of the flange. May be used to seal flanges with rough surface

Easy installation and handy use.

Excellent Sealability

Technical Data Sheet

Application Area

The Spiral Wound Gaskets are mainly used in valves &pipes, pressure vessel, condenser, heat exchanger flanges in oil, chemical, metallurgy, vessel and mechanical industries.

NOTE: rear shaft seal is not covered in this video – this information can be found online. If you have a deep groove worn into the shaft from this seal, you may have to install the new one in a slightly different position to contact an undamaged part of the shaft to prevent leakage from the backside of the pump.

The MB re-seal kit only includes the front cover o-ring and rear shaft seal – if your pump continues to leak from the front cover after replacement of this while operating, the internal O-rings will be leaking. With time and heat they have all gone hard and brittle now anyway.The internal o-rings have to be sourced from the aftermarket. They are not available as a spare part from MB. They want the whole pump replaced in such case.

Also note, i suggest using something like silcon o-ring grease to allow easy installation of the internal o-rings. Oil on its own may allow the rings to bind and be cut, chipped or shaved, resulting in enormous leaks.
