ULTRASeal 151 - PPC's Single Metal Bellows Cartridge Seal. The U-151 is a low-profile design allowing it to fit virtually any pump without modification to the stuffing box. Like the 1500E, it incorporates tangential flush ports for both clockwise and counter-clockwise shaft rotations. The rotary bellows assembly is pin driven, eliminating spinning due to setscrews backing out or sleeve distortion due to over tightening. As with all PPC's seals, the U-151 is available in a wide variety of materials and sizes allowing for its' use in many services. |
