APPLICATIONSeal X packing products are used to seal shafts, rods, and seats, to prevent the escape of gas or fluids.The main fields of application are:

> static seals (covers, frames, furnace doors, boilers);> stem seals (valves);> moving shaft seals (plunger pumps);> rotating shafts (centrifugal pumps, mixers, stirrers);> pumps.

CHARACTERISTICSDepending on the end use, certain characteristics must be assessed> Flexibility> Elasticity and elastic return - to guarantee tightness under pressure> Homogeneity - acting as a guarantee of efficient service and longer life> Compact external surfaces - guaranteeing tightness while avoiding excessive tightening pressure and possible wear to the shaft> Impregnation to the heart - offering guaranteed tightness to improve efficiency and the value of the application

COMPONENTSSeal X products have different components to suit different applications.The main components are:

> graphite fibres (providing extra chemical and thermal resistance);

> insulating glass and ceramic fibres (generally used for static thermo resistant seals);

> vegetal fibres, such as cotton, linen, ramie fibre and hemp (especially suited to applications with cold water and where hard-wearing qualities are required);

> synthetic fibres, such as ptfe, polyester, aramidic and acrylic fibres (suitable for producing packing with high resistance to chemicals and corrosive agents);

> metals, such as stainless steel, copper and inconel (used to strengthen the packing and thus increase its mechanical strength at high temperatures and pressures);

> lubricants and binders, essential when using packing as these must not attack the contact fluids or corrode the metals surrounding the packing or any metal in this, while at the same time eliminating friction.

These products are suitable for a large range of applications according to your specific requirements.

SX9040 fluorpack®

CHARACTERISTICS Fluorpack®, designed with an exclusive Lenzing fiber,is a braided packing made of expanded PTFE yarns containing capsulated graphite particles and components with lubricating powers and suitable for conducting heat, grant a high thermal conductivity as well as resistance to chemical agents and to ageing. This homogenous structure permits the packing not to lose its components during the operation, reduces to a minimum the risk of wear on the shaft and prevents the fluid from being polluted by the particles that detach themselves from the packing. It has a longer working life if com-pared with traditional packings. Thanks to his plasticity and high flexibility, Fluorpack® renders the installation and the disassembly of the gasket easier, and labour costs may be considerably reduced. Only the boxes with the blue label are Fluorpack® 100% packings, the exclusive trade mark of Texpack® made of Lenzing fibers. This blue label guarantees the 100% Fluorpack® quality.

ADVANTAGES: ong working life, universal chemical resistance, excellent themal conductivity for high shaft speed, does neither hydrolyze nor harden, clean and easy to cut, not abrasive, better heat dissipation, lower weight loss and consequent minor shrinkage, asbestos-free.

APPLICATIONS CHEMICAL INDUSTRY: Pumps and control valves, mixers and dischargers for acids, alkali, resins, solvents. PETROLCHEMICAL INDUSTRY: Pumps and valves for acids, asphalt, vapour, mud, chemical products,caustic solutions. MINING INDUSTRY: Drainage pumps.TEXTILE INDUSTRY: Bleaches, dyestuffs, acids, filtered liquids, dirty water.
