Blackmer Pumps Ease Transport of ULSD With Self-Priming, Dry Run Capabilities

Grand Rapids, MIOne of the ancillary concerns associated with the Environmental Protection Agency's new regulations requiring the use of 15-ppm on-road ultra-low-sulfur-diesel (ULSD) fuel, which came into effect last year, was whether the available infrastructure could handle the demands of loading and unloading this new fuel at various drop points along the supply chain. The GX and X Series line of positive displacement sliding vane pumps from Blackmer, a global leader in rotary vane positive displacement, eccentric disc and centrifugal pump technologies, has put those concerns at ease. The new 15-ppm ULSD, which replaced the 500-ppm low-sulfur diesel (LSD) standard for on-road use, has a lower lubricity than LSD because of the amount of sulfur, a natural lubricating agent, that has been removed from the fuel.

Blackmer's GX and X Series sliding vane pumps are ideal for handling ULSD due to their self-priming and dry run capabilities. Used for general transfer duty, the GX pump line is available in port sizes from 2 inch to 4 inches, flow rates from 30 to 520 gpm (114-1,855 lpm), while the X pump line is available in port sizes from 1 inch to 4 inches, flow rates from 3 to 510 gpm (11-1,930 lpm). The GX and X Series are both able to operate in temperatures to 300°F and relief valve pressures to 125 psi. These pumps are ideally suited for handling ULSD thanks to their self-priming and high suction lift capabilities, which make them ideal for pumping from underground storage tanks and bulk plants, stripping lines, and completely removing the heel from rail and transport tankers.

The vane technology principles of the GX and X Series ensure proper sealing and volumetric output performance, even after significant in-service time. This eliminates the efficiency-robbing "slip" that shortens lobe and gear pump life, and improves production yields by stripping lines clean of residual product. The GX and X Series provides smooth, sliding vane action without metal-to-metal contact, which reduces pump friction, eliminates galling and minimizes agitation of fluids, resulting in shear-sensitive, mild handling of thin liquids without product degradation. External ball bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk. Maintenance is also easy as the vanes can be easily replaced without removing the pump from the piping system.
