Impeller periphery
Witryna17 gru 2011 · For a radial vane design, this flow will be directed out to the impeller periphery making this area the predetermined point of wear. For true heavy duty radial vane recessed impeller pumps, the casing will not suffer this wear as it is protected by an independent heavy duty peripheral wear plate assembly.
