| The parallel spring family range of designs are ideal for a wide spectrum of application conditions, ranging from general duties through to more demanding applications, through their accommodating Single Springs and elastomer Diaphragms. The seals are highly effective and widely utilised in pumps, mixers, agitators, compressors and other rotary shaft equipment. |
 TYPE 1 Robust, long working length, highly accommodating and reliable, rubber diaphragm bi-directionnal balanced seal, which provides enhanced seal capability, performance and life. The Type 1 has a retainer backing plate, a narrow profile and a no spring base plate.  TYPE 2 Robust, short working length, highly accommodating and reliable, rubber diaphragm balanced seal, which provides enhanced seal capability, performance and life. The Type 2 coil fits over the seal head, reducing the overall working length, making this seal suitable for short gland depth applications.
