| RIS A non-clogging, component seal for tough slurry applications | ||||||||||||||||
| The RIS seal has a unique, non-clogging design that does not utilize springs or bellows. The innovative design of the adaptive components allows the seal to be installed from the wet-end of the pump and to be adjusted externally. With many pump designs, the seal may be reset automatically during impeller clearance adjustment. | ||||||||||||||||
| Features and Benefits The stationary seal face is attached to a smoothly contoured flexible rubber element which holds the seal faces together and absorbs relative shaft movement when the pump is in operation. A true non-clogging design provides longer MTBF with the rubber in shear component. External adjustments compensate for minor seal wear with no pump disassembly and compensate for pump misalignment. A lack of dynamic gaskets provides longer MTBF by eliminating seal face hang-ups. Extensive factory and field tests on hard slurries insures consistent and peak performance. With the control of slurry composition no flush is required, saving water and energy costs. Eliminating process leakage reduces water and disposal problems, packing sleeve wear and bearing failures. | ||||||||||||||||
