Parker Filter Division Europe has introduced a Self-sealing spring mechanism to replace the traditional reusable metal top seat spring assembly for double open end filter cartridge installations and bring about easier and faster cartridge changeout within the process industries, particularly chemical, food, beverage and coatings.
Designed for use with all Parker 2½ inch OD wound, pleated and bonded cartridges, the integral polypropylene Self-sealing spring, in conjunction with a standard extended core, eliminates all loose metal components in the vessel and reduces the risk of by-pass on conventional double open ended cartridges.
The Self-sealing spring eliminates the need for a metal top seat spring assembly and will be the particularly advantageous in industrial multi-cartridge vessels. In effect, the Self-Sealing Spring results in a single open end design, but with the open end still sealing on a knife-edge sump seat.
