Product Description

Type 2220 is a customer-fitted (OEM standard) dual, balanced cartridge seal designed for the severe applications found in the pulp and paper industry and slurry applications. This seal is typically used in pumps for abrasive and environmentally hazardous liquids in cooking, evaporation and causticizing facilities in pulp mills. It is designed as a dual-pressurized (double) seal, but incorporates a patented double-balance feature which also allows it to be used as an unpressurized (tandem) dual seal
