ABSTRACT A mechanical seal mounting assembly for a centri- fugal high solids concentration slurry pump is disclosed. A rotating seal ring adapter is secured to the pump's im- peller drive shaft for rotation with the shaft. A stationary seal ring adapter is secured to a first end of a seal carrier which extends through the pump's back plate. A split gland ring is attached to a second end of the seal carrier and is supported by gland nuts threadedly carried on gland bolts. The gland bolts are attached to a bearing assembly for the pump shaft. Axial movement of the pump shaft to effect im- peller clearance seal adjustment is possible without disturb- ing the mechanical seal adjustment. An O-ring is interposed between the pump back plate and the seal carrier and is held in place by an O-ring retainer secured to the back plate of the pump.
