Viking GB-425

Description

The GB-425 external gear pump is used for pipeline injection in upstream and midstream oil and gas applications. It is suited for high-flow, high-pressure transfer of low-viscosity fluids in continuous operation. It delivers flows up to 700 GPM (159 m³/h) with pressures up to 103 bar (1500 PSI). The pump operates across viscosities from 1 to 20 cP, supporting stable performance in injection systems. Constructed with advanced hardened materials in critical wear areas, the pump provides extended service life in demanding conditions. The rebuildable design allows all wear components to be replaced, restoring performance without full unit replacement. The pump features a back pull-out mechanical seal and robust thrust bearing design to support high-pressure operation. Modular porting and compact base-mounted construction enable flexible installation and simplified maintenance.
