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 hardening 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 sensitive 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 wrongly assembled, the spring will never be preloaded incorrectly, and that sensitive area will never be subjected to greasy fingers or dirt. All these factors are common causes of short seal 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 minimized. This translates into significant savings for your business.
