Long Spring O Ring Type Grundfos Mechanical Seal Replacement GLF-2





Grundfos mechanical seal GRF-E is a pump seal which fit for grundfos pump model CRK2/CR4/CRK8/CRK16, CRK2/4 AUUV, CRK8/16 AUUV, CRK2/4

This grundfos seal is a unbalance seal with oring component, Robust O-ring seal featuring a rigid torque transmission design required for hard material pairings (WC/WC or SiC/SiC), even where lubrication is poor. The dynamic secondary seal is an O-ring. This involves a risk of wear on the shaft under the O-ring and of seal hang-up (blocking of axial movement of the rotating seal ring).

Users can choose carbon, silicon, and tungsten carbide for this mechanical seal as seal face, if for high temerperature, we suggest to choose rubber seal viton for the rubber parts.
