Unique cartridge seal design The cartridge seal used in the CR line combines the best features of standard seals, wrapped up in an ingenious cartridge design that provides unique advantages. All of these ensure extra reliability. The durable seal is made from hardwearing materials which prevent downtime and prolong the lifetime of the seal. All axial movement has been eliminated, preventing wear of the shaft and rubber parts – a typical problem area for traditional seals. The cartridge seal is a balanced type seal, a fact which makes it less insensitive to pressure.We know, however, that even the best of materials are not necessarily enough to guarantee success in real life. Safe and easy handling The peerless cartridge design ensures that the seal compo­nents will never be assembled wrongly, the spring will never be incorrectly preloaded, and that sensitive surfaces will never be subjected to greasy fingers or dirt. All these factors are common causes of short seal lifetimes in other pumps. The cartridge design also enables rapid replacement when the seal ultimately does need changing after a long period of service. All in all, downtime is minimised. Naturally, this translates into significant savings for your business.
