Standard stainless rotors wear fast when you're running abrasive or high-viscosity fluids. Tungsten carbide changes that. This rotor is engineered for progressive cavity pumps handling filled adhesives, silicones with glass beads, and other abrasive media that chew through softer materials. Hardness rating typically 1,500–1,600 HV — roughly 10× harder than stainless steel — so you get dramatically extended service life between shutdowns. Fits DR progressive cavity pump models. Drop-in replacement for the standard rotor. No housing modifications required. If you're replacing rotors more often than you'd like, this is the fix.
