CENTRIFUGAL EXPELLER & STUFFING BOX

Centrifugal Expeller & Stuffing Box

Centrifugal sealing components for slurry pumps: expeller, expeller ring, shaft sleeve, and packed stuffing box. We do not sell mechanical seals because mineral slurry pumps operate in highly corrosive and abrasive conditions.

Why We Use Centrifugal Expellers & Stuffing Boxes (No Mechanical Seals)

In mineral slurry pumping with corrosive reagents and abrasive suspended solids, delicate flat-face mechanical seals rapidly fracture or seize. Our slurry pumps use a centrifugal expeller paired with an expeller ring and braided-packing stuffing box, operating dry without external gland water that would dilute the process slurry.

Sealing Assembly Components

Centrifugal Expeller High Chrome or Rubber; generates a dynamic pressure ring that repels slurry from the shaft
Expeller Ring & Stuffing Box Heavy-duty casting housing the braided packing and lantern ring
Shaft Sleeve Hardened stainless steel sleeve protecting the Bearing Assembly shaft
Braided Packing PTFE and graphite synthetic packing for static shutdown sealing

Zero Slurry Dilution

Centrifugal expeller sealing eliminates external gland water injection, preserving pulp density stability feeding hydrocyclones and flotation banks.
