Viking SG-405

The SG-405 spur gear pump is used for precise low to moderate flow applications such as pipeline injection, sampling, and oil polishing. It is suited for systems requiring accurate metering and reliable high-pressure performance. It delivers flows from 2.6 to 42.4 L/min (0.7 to 11.2 GPM) with pressures up to 34 bar (500 PSI). The pump operates across viscosities from 1 to 250,000 cSt, supporting stable transfer across a wide range of fluids. Constructed with needle bearings or optional sleeve bearings, the pump supports high-pressure operation and durability. The design ensures consistent performance in demanding industrial environments. The pump supports flexible configurations including motor-mounted or bracket-mounted drives. Multiple porting options and compact construction allow integration into injection and sampling systems.
