MARKETING & SUPPLY A selection of companies' latest offerings BULK PLANT ROUND-UP BLACKMER® LGL3021 MULTI-PURPOSE LPG PUMP Blackmer® LGL3021 Multi- Purpose LPG Pumps have been specifically designed for bulk plant and terminal applications, is UL-Listed and approved for use on propane, butane, butane/ propane mixes and anhydrous ammonia applications. Based on Blackmer's standard LGLD3 transfer pump, the LGL3021 provides the same horsepower requirements and foot-to-flange and flange-to-flange dimen- sions as competitive pumps. This allows for easy installation during pump changeovers or plant maintenance without chang- ing piping or motor drives because the inlet and discharge flanges are on the pump shaft centerline. What separates the LGL3021 from competitive pumps is that it provides 13 percent to 25 percent more flow depending on the LPG installation and application conditions, a major consideration during bulk plant and terminal operations. LGL3021 pumps also feature ductile iron construction with an internal relief valve that protects against excessive pressures, ensuring performance and reliabil- ity even under the most severe service conditions. Blackmer – Grand Rapids, MI – www.blackmer.com GRISWOLD™ 811 SERIES CENTRIFUGAL PUMPS WITH 17-INCH IMPELLER FOR BULK STATIONS Griswold™ 811 Series ANSI Centrifugal Pumps with a 17- inch impeller are ideal for high capacity transfer within large bulk storage operations. The 811 ANSI Series pumps meet the needs of bulk storage operators because they feature open impel- lers with two times the wear area of a closed design, which optimizes the performance of the pump's open impeller and allows renewable performance. This open-impeller design fea- ture also minimizes concentrated wear by balancing the hydraulic axial thrust load and reducing the stuffing-box pres- sure. This not only facilitates corrosive, abrasive, solid and stringy-fiber handling, but also simplifies maintenance, extends pump life and reduces repair costs. Since casings of the 811 Series pumps can be constructed of a wide choice of materials, including ductile iron, 316 stainless steel, CD4MCu and alloy 20, they are able to meet a wide array of transfer applications found within bulk storage operations, such as petroleum, bio- fuels, chemicals and vegetable oils, to name a few. They are 22 OCTOBER 2012 constructed through investment and no-bake casting processes to ensure smooth, precise, superior finished that guarantee consistent, reliable performance.
