Viking 4624B

The 4624B internal gear pump is used for handling inks, resins, starch, and other fluids containing abrasive particles. It is suited for applications where wear resistance and sealing reliability are critical. It delivers flows from 0.75 to 182 GPM (0.17 to 41 m³/h) with pressures up to 150 PSI (10 bar). The pump operates across viscosities from 38 to 250,000 SSU, supporting stable transfer of abrasive and viscous fluids. Constructed with ultra-hard tungsten carbide idler pin and bushing, the pump minimizes wear in key areas exposed to abrasive materials. This supports extended service life in demanding operating conditions. The pump features a behind-the-rotor mechanical seal with silicon carbide faces and an external flush line to reduce solids buildup. A grease-lubricated bracket bushing further isolates critical components from the pumped liquid.
