Single cartridge seal, balanced design
The Style-20 seal is a single balanced cartridge seal that is (similar to the Style-19), capable of accommodating 1/8” (03.18MM) of radial shaft movement. The Style-20 is a stationary design and can operate at higher speed and pressures than many other alternatives. Because it is a single seal, the faces must be flooded while in service.
