Technical Specifications

Description &Advantages

 

The NS-43 TDMA tandem seal for multi-fluid outside sealing application is used to seal pistons and plungers. It can be used with mineral oils and in modified form with compressed air. The TDMA seal consists of two parts, an elastic ring of PUR with 2 sealing lips and a slide ring of abrasion-resistant PTFE-Bronze Compound with 2 sealing edges. Prior to fitting, the sealing lips protrude beyond the nominal diameter of the seal, and are pressed against the cylinder wall after fitting. Thus effective sealing is provided even at zero pressure. The slide ring is surrounded by the elastomer sealing ring and moves axially in direct contact with the inside of the tube. With increasing pressure and compression of the elastic ring, it is the slide ring which is predominantly pressed against the inside of the tube. The outer sealing surface of the TDMA mainly comprises the slide ring which has excellent sliding properties.
