Michael Smith Engineers (MSE) has extended the Viking range of high-pressure external gear pumps to include models that provide flows from 0.2 litre/min up to 760 litre/min.

The SG range of Viking positive displacement pumps includes models rated for maximum continuous pressures up to 34 bar and maximum intermittent pressures up to 172 bar.

According to the company, reliability and minimal maintenance are key benefits of the SG series of pumps, and their design ensures extended seal and bearing life, keeping downtime to a minimum.

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

Axial (back-and-forth) movement is minimised by spur-type gears, instead of helical gears, which can cause gear thrust on contact components.

Also, the pumps incorporate anti-friction needle bearings as standard, which eliminate bearing wear at start-up and shutdown.

MSE added that the pumps are designed with application flexibility in mind.

They have a high pressure capability (up to 35 bar on some models), resulting in a compact that delivers higher volumes at higher pressures.

Multi-section models with multiple porting options mean that two or more separate pumping sections driven by a single source can be configured with separate ports or common suction or common discharge ports.

This means each section can operate at different pressures and/or flows, making the pumps adaptable to unique pumping applications.

Optional carbon-graphite bearings are available for very low viscosities or silicon carbide for abrasives.

As a result of the range of models, configurations and material options, Viking SG series gear pumps are suitable for numerous pumping applications, including: centralised lubrication systems; polyurethane metering and mixing; compressor lubrication; burner feed; pipeline sampling; heat transfer and adhesive; and sealant dispersion.
