2 INTRODUTION Vulcan s Parallel pring Diaphragm Type eals are highly proficient and widely utilised, covering all standard pump shaft, working length and housing size ranges. PPLITION 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 ingle prings and elastomer Diaphragms. The seals are highly effective and widely utilised in pumps, mixers, agitators, compressors and other rotary shaft equipment. TNDRD VULN PRLLEL TYPE Types 10, 20 and 20 Parallel spring, rubber diaphragm seals to common industry standard dimensions. Fitted as standard with Type 20 boot mounted seats, Type 20 has a Type 21 O -Ring mounted stationary. Types 11, 11J and 22 s above, to common merican standard dimensions, fitted with a Type 11 boot mounted seats, or Type 11J has a Type 31 O -Ring mounted seat. Types U11/N11 s above Type 11, but to full NI compatibility, through incorporating a narrow profile seal design. Type U11 utilises the same seal head internal design as our Type 24, whilst Type N11 incorporates an elastomer resiliently mounted ring face. Type 24 eries s above but to full DIN24960 (EN1276) dimensions, K-length. Type 24 is supplied with a Type 24 boot mounted seat as standard. You should specify Type 24, if a Type 24.DIN stationary is required and Type 24L for the Type 24.DINL stationary. TNDRD OMPONENT VULN DEIGN DVNTGE ccommodating The seal head automatically adjusts to accommodate misalignment and seal face wear, through the design and flexibility of the rubber diaphragm. Improved Designs Vulcan s attention to detail and modern in-house design and manufacturing facilities, have enabled Vulcan to create Parallel pring eals, with additional improvements to the original designs, whilst still maintaining the main design features, such as self aligning, non-fretting / clogging and vacuum application suitability. These improvements result in a superior Vulcan Mechanical eal, to both the original replacement seal and their other direct market copies. Retained omponents Faces and base plates are retained by adhesive grease and by mating components, respectively, making handling and fitting easier and more secure. ustomisable The technically efficient and highly versatile, parallel spring, seal design can be readily customised to suit individual requirements; where a standard seal or seat cannot be utilised. Vulcan can assist in the design of special production runs to fully satisfy customer requirements. Quality wide selection of high quality face materials and elastomers are readily available as standard. Reliability The resulting Vulcan Quality eal and the high strength and flexibility of the diaphragm, provide a very reliable and accommodating mechanical seal design.
