Dynamic connection sealants are the most commonly used seal type in pump technology. They are used in fittings and wherever there are rotary, reciprocating or other movements. Materials used today (graphite, teflon, carbon fiber and aramid) allow these seals to work in a variety of very aggressive environments and at a wide temperature range. Combinations of the above yarns allows for modified properties of the sealant and matching them to the required operating conditions

All of the above sealants have a square cross section of 4 to 50 mm. However, it is possible to make sealants for the individual needs of the client. For selected sealants, we place in the orientation table the weight (in grams) for 1 mb of sealant depending on its cross-section.

Above ropes are used in the process of sealing static connections, i.e. those in which there is no relative movement and as thermal insulation. Depending on the nature of the work, various types of glass, ceramic and organic yarns, fillings, impregnates and weaves are used. As often as possible, combinations of yarns are used which allow for optimum performance. The materials make them resistant to most aggressive chemicals except fluoride, strong alkali, phosphoric acid, hydrofluoric acid, sulfuric acid. Their additional advantage is the resistance to decay, fungi and bacteria.

All cords are available in standard sections: square and circular and non-standard rectangular cross-sections. Cross sectional height from 3 to 80 mm. However, there is a possibility to make a rope for individual customer order.
