RSD SEALS

 

TYPE A ...........................TYPE B................................TYPE W

TYPE 2................TYPE 3

Replacement seals for rotating equipment including pumps, compressors, mixers, agitators, speed reducers and related equipment. The seal assembly maintains contact between the surface of the seal face and the mating stationary seat with spring pressure. Spring rates are checked at actual operating lengths. Parts which retain seal faces are held to ±.002" tolerances. Stocks are backed by thousands of square feet of inventory. Most items are in stock. Out of stock items can be shipped from the factory the same day they are received.

680 Bellows Seals

The Type 680 Series are high performance bellows seals for applications such as water, waste water, and other general process fluids. These seals have no sliding secondary seals which eliminates the problem of seal face hang up, the major cause of failure of spring loads seals. Effective contact of sealing faces is maintained, and leakage to the atmosphere is minimized. By using a static secondary seal, damaging shaft or sleeve fretting and subsequent premature seal failure are avoided. Unlike springs, bellows are non-clogging and their durable design can withstand higher viscosity fluids and a higher concentration of solids. The Type 680 is ideal for general purpose application. It's alloy 20 bellows provide excellent corrosion resistance. May be used in temperatures from -100°F to 400°F, pressures up to 300 PSI and speeds up to 4500 FPM.

EZ-1 Carteridge Seal

The EZ-1 welded metal bellows cartridge seal has a unique self centering, slide on and tight design that eliminates the need for prints, scribe lines or clips to remove. It is available with hard faces for abrasive applications. The design incorporates a flush port to bring fluid to the seal faces to provide lubrication, cooling and cleansing action. Glass filled Teflon® retaining ring allows for easy start ups and increased chemical resistance. EZ-1 fits small cross section stuffing boxes and fits over 500 common pumps without modification. Only two secondary seals (O-rings). Viton standard with EPR and Teflon® in the box for easy change out.

Split Seal

Type 3710 Cartridge Split Seal eliminates the need to dismantle any piece of equipment, large or small. It's full split design can be installed in less than 30 minutes, either on the packing sleeve or directly on the shaft. The cartridge design eliminates any measuring or centering of the seal, making assembly easy, while assuring long seal life. Available with hard faces for abrasive applications. All O-rings & non-clogging finger springs are pre-installed. Height & centering is automatically set without measurements or need for dial indicator. Aligning seal face halves is no longer a concern due to special retaining rings which hold perfect alignment.
