The of this type is so designed as to be applicable to the of ISO code or ANSI code, and is a sister product of type-aau and type-abu. The of this type is a balance type of type-aeu and type-afu shown above. The of this type is an outside of which standard type is made by combining the SiC materials having excellent corrosion-resisting performance and -resisting performance, to the sliding material, and is suitable to the to which strict corrosion-resisting performance is required. The knife edge of similar construction is also available to the high-viscosity liquid. (Type-EAK) The of this type is an outside type in which O-ring is used for shaft packing, and can be easily maintained, as the components are arranged at the outside the equipment body. Since it can directly the gas within vessel, it is not necessary to prepare the ant required for double. The of this type is a multi- type in which the SiC is used independently for ring and the drive collar is grooved in radial pattern.

There is a hole provided at the shaft O-ring of rotary ring, to prevent the follow-up failure due φ20~φ130 to clogging. CGU HGU CFU CEU PEU PFU PEU PFU US-2 US-2 Rotary type rubber bellows The of this type is adopted officially as a type US-2 by the Japanese Marine Equipment Association and uses the which is hardly affected by corrosion or slurry. It is also applicable in all industries except for marine use. The of this type is an improved version of marine-use. Since the adopts the rubber bellows, it is of such construction as to allow the follow-up failure to hardly occur at the shaft packing. In addition, the also adopts the which is hardly affected by corrosion or slurry. The of this type is a which is so designed as to be applicable to the of ISO code, and of which sliding material uses the SiC for standard feature. It is applicable to the liquid. The knife edge of similar construction is also available to the high-viscosity liquid. (Types: CEL, CFL, pressure: 0.5MPa) The of this type is a having excellent corrosion-resisting performance and slurry-resisting performance, adopts the clutch mechanism to the rotation torque transmission of, and is a which makes up for the disadvantages of drive. type of type-peu and type-pfu shown above φ20~φ MPa φ20~φ MPa φ18~φ55 1.3MPa φ18~φ MPa φ18~φ130 Fresh water, seawater, lubrication oil Fresh water, seawater, lubrication oil Fresh water, seawater, lubrication oil, Highviscosity slurry-mixed crystalline liquid Highviscosity slurry-mixed crystalline liquid 2

3 s (for high peripheral speed) (1/1) GAKEM Pillar Cassette cartridge GHB type The is a cartridge type applicable to a wide range of fluids ranging from fresh water to high-viscosity slurry. Since the end surface of uses the Sic having excellent wear-resisting performance and -resisting performance, the long-time service life is expectable. Besides, it can be also attached to the of ISO code or DIN code, as it is designed for compact type. Since the of this type is a standard type stationary type, it is designed for compact type, and the is arranged at the atmospheric side, it will not cause any clogging. For center impeller type or vertical, it is not necessary to perform any dimension adjustment work, as it is designed for cartridge type by the setting claw. φ20~φ MPa limit: 40m/s φ30~φ200 Bellows s (1/1) QAK The of this type uses the molded metal type molded bellows, it is designed for sharp knife edge at metal one side, and is developed to provide the bellows stabilized performance to high-viscosity fluid, (for high- polymerizable liquid and coagulative liquid. viscosity liquid) φ20~φ106 QBS type welded metal bellows (for high temperature) The of this type is a stationary type which uses the welded metal bellows having excellent pressure-resisting performance. Since it does not use any shaft packing, it is not necessary to make consideration the heat-resisting limit of packing, and is applicable to the high-temperature use. 3.0MPa 60m/s Heat-resisting limit: 450, Chemical for oil refining, petro and, etc. Highviscosity polymerizable liquids such as pulp, food, paint, resin, etc. High-load for hightemperature, lowtemperature, high-speed, highpressure WCB WBR Chemi- Mighty Rotary type PTFE bellows (for fluid) Bellows pack Rotary type welded metal bellows (for high temp.) The of this type is an outside having excellent corrosion-resisting performance, of which bellows uses PTFE, and the sliding material uses SiC. It also provides the excellent performance as a dry for agitator, etc. The bellows of this type is a metal bellows which can be attached to the of ISO code or DIN code, and assures the excellent performance in taking the corrective measure against operation failure of shaft packing. This is applicable to a wide range of fluid, as its bellows is made of inconel. φ23~φ MPa limit: 14m/s φ20~φ MPa limit: 25m/s φ20~φ100 Each liquid and slurry liquid Utility, low-pressure/ mediumpressure 3

4 Split s (1/1) SCU RⅡ type outside SCU ARⅡ type outside Since the soft material side forming its surface is designed for split type, it is not necessary to disassemble the equipment in the event of repair. It is also possible for of this type to execute the daily inspection, and to adjust the force, as it is arranged outside. The adoption of special carbon having excellent lubricity has made it possible to perform the water-free operation or aerial operation for over one hour. Besides, the maintenance is executable without disassembling the equipment, as the fixed side sliding part and rotary side part are of split construction. limit: 13m/s φ20~φ MPa limit: 12m/s φ35~φ260 Water, sewage Vertical shaft type advance stand-by, sewage/ rainwater discharge, river water 4

It is applicable to the gas which is not allowed to leak to the outside, or to the gas containing powder, etc. The of this type is a in which the unique groove like phoenix feather is arranged on the surface, to utilize the dynamic pressure(provided by barrier) effectively. It is applicable to a wide range within range from compressor and steam turbine to blower. The of this type is a dynamic pressure end surface non-contact type dry gas to which automatic clearance adjustment function is provided. When the is started with gas supplied in the equipment at +2bar prior to operation, the dynamic pressure is generated by the groove arranged at the rotary ring, by which the fixed clearance is secured on the surface, to prevent the fluid within equipment from leaking. Since the chamber is pressurized, using the nitrogen gas, it becomes possible to simplify the attached unit, by which it is not necessary to arrange the oil unit, etc. which had been required for conventional double. The of this type is a dry contact for secondary, and is applicable as a unit in substitute for tandem. Since the surface is grooved for reduction of load, the dry-resisting performance is improved. The long service life is also assured, as the special lubricant is impregnated to the ring. 80m/s PEC-3SA 1.05MPa 80m/s PPG-1RB 20m/s PPG-3SB 10.0MPa 150m/s -1~16Bar limit: 3~40m/s φ50~φ MPa φ20~φ130 Turbine, compressor Each process Each process 5
