Standard Features
Grav Co's Graviflo Rapid Finish machines feature solid, heavy duty construction which eliminates disc deflection and ensures that a non-contact seal gap is maintained. Our structures are designed to maintain concentricity of the disc to the stationary tub, whether the machine is operating or at rest.

The unique bearing housing assembly with stainless steel components utilize thrust bearings and lock-nuts to prevent upward or downward thrust.

All Rapid Finish machine include the "flow through the seal compound metering system". All but the RF-20 include the patented replaceable wear rings. They are available fully automated and manual and come in several sizes.
