The range of simple, yet reliable Viking external gear pumps has been extended and now features 29 models to provide flows from 0.2 to 760L/min.

Available through Michael Smith Engineers, the SG range of Viking positive displacement pumps includes models rated for maximum continuous pressures to 34 bar and maximum intermittent pressures to 172 bar. Reliability and minimal maintenance are said to be key benefits of the SG Series due to their special design. This is said to ensure extended seal and bearing life, reducing downtime.

For example, shaft movement is minimised which lengthens seal life, radial (side-to-side) movement, or misalignment, is prevented by closecoupled motor mounts, or outboard bearings for foot-mounted pumps.

Axial (back-and-forth) movement is minimised by spur-type gears. Also, the pumps incorporate as standard, anti-friction needle bearings which eliminate bearing wear at start-up and shutdown.
