PolyPak seal combines the O-ring as an energizer with the lip seal to form a special sealing device, which can seal in vacuum and high and low pressure applications. It is a multi-purpose seal. PolyPak advantages: PolyPak has obvious advantages over the traditional lip seal, because there is basically no lip load in the basic seal design, so it is easy to leak under low pressure. PolyPak is an ext...
The convertible rotary seal has a housing for receiving the polishing rod. A mandrel is rotatably mounted in the seal housing and surrounds the polish rod. A wear sleeve surrounding the mandrel engages a primary seal. A secondary seal engages the mandrel and polish rod and rotates therewith but may be converted for use as a static seal if necessary. A locking mechanism selectively secures the mand...
PolyPak seal is a precision molded multi-purpose seal that combines an o-ring type synthetic rubber o-spring with a traditional lip seal to produce a unique sealing device capable of sealing both vacuum, high and low pressure. Traditional lip seals are prone to leakage at low pressure because the inherent lip load in basic seal design is small or non-existent. However, PolyPak is an extruded seal ...
Well drilling is the process of extracting oil and natural gas from the ground (both onshore and offshore). As the well becomes deeper, the seals used in drilling must adapt to increasingly harsh environments. System pressures up to 2,070 bar (30,000PSI)and operating temperature extremes between -50℃(-58℉)and 220℃(428℉) are common. At the same time, seals used in drilling applications must have ex...
In the industrial field, the importance of sealing technology is self-evident. It is not only related to the normal operation of the equipment, but also directly affects the production efficiency, product quality and safety. Among many sealing solutions, polypak stands out for its superior performance and innovative design. The polypak is a key component of its sealing system. This rubber seal has...
