Goulds Pumps, one of the premier fluid brands of ITT Industries, is now offering Seal Plus, a highly versatile single and double cartridge all purpose mechanical seal. Seal Plus features an Aflas® o-ring pusher design which provides versatility, reliability and lower cost. It is the logical alternative to component seals. The single seal (SP1) features a carbon or silicon carbide rotating face with a silicon carbide stationary face and 316 stainless steel metal parts. A standard carbon restricting bushing is supplied with a cast 316 stainless steel flush, vent and drain glands.
The double seal (SP2) also, uses a carbon or silicon carbide inboard rotating face and 316 stainless steel metal parts to insure optimum chemical compatibility. It has a silicon carbide stationary face with a carbon versus silicon carbide outboard face combination and a cast 316 stainless steel gland with an inlet and outlet port.
The Seal Plus is a fully balanced design which allows for higher working pressures. The hydraulically balanced faces ensure optimum fluid film at the faces during process fluctuations. The true metal-to-metal drive eliminates slippage and the potential of shearing drive pins. Set screws clamp directly to the shaft sleeve ensuring a positive lock. The maximum operating pressure @ 3600rpm is 300psi@20º F (-5º C), and the maximum operating temperature is 400º F (205º C).
