PLUNGERS

Product catalog summary

Overview: The document outlines specifications and guidelines for BOTECO's W-S plungers, detailing materials, dimensions, and assembly instructions for various models.

Specifications: Multiple plunger models are described, highlighting dimensions and material compositions. Key materials include reinforced polyamide for knobs and high-resistance steel or stainless steel for plunger pins and springs. Finishes include black satin and black-oxide.

Procedures: Assembly instructions stress the importance of creating a lodging hole with a tolerance of H7. For some models, knobs are supplied separately to prevent damage during welding and should be attached post-cooling.

Versions: Several plunger versions are detailed:

W800 and W801: Black oxide treated, with or without lock nut.
W802 and W803: Black oxide treated, with or without lock nut.
W810 and W811: Black oxide treated with handwheel locking system, with or without lock nut.
W804 and W805: Black oxide treated without ring nut, with or without lock nut.

Stainless steel versions (CIN) are available for each model.

Recommendations: The use of a zinc-plated locking wrench is advised for assembly, with specific tolerances recommended for the lodging hole. Custom color variations and separate nut supply are available upon request.

Stock Information: Stock presence percentages for different models indicate availability levels.

Additional Specifications: Models W793 to W798 are available in galvanized and stainless steel versions, with detailed dimensions and materials specified.

Standards and Norms: Materials include AISI 303 and AISI 304 stainless steel, with components adhering to UNI 5589 standards. Knobs are resistant to oils and greases.
