Features

Benefits

Disc Rise Mechanism

Large, unobstructed opening for fast, complete emptying; minimizes residue in silos/tanks.

Abrasion-Resistant Build

Ductile iron, 316L stainless steel, or tungsten carbide-coated plungers withstand grit, grains, and chemicals.

Tight Sealing

PTFE/rubber seals prevent leakage when closed—critical for hazardous or valuable materials.

Self-Cleaning Action

Plunger movement dislodges stuck material, reducing clogs in sticky/granular service (cement, sugar).

Easy Access

Quick removal of plunger/seals for maintenance—cuts downtime in continuous discharge operations.
