The seal chambers of 811 Series are engineered to provide an optimum seal environment for heat dissipation, solids, entrapped air and vapor. The oversized seal chambers have increased radial clearances between the mechanical seal and seal chamber wall to improve circulation of liquid to and from seal faces. The seal chambers are available in three styles: standard bore, for packing or mechanical seals handling mild fluid at ambient temperatures; large bore, which can handle solid greater than 10 percent when used with a close-clearance throat bushing and external flush; and tapered bore, which services 10 percent solids or fluids containing entrained air or vapors.
