CANADA’S LEADER IN ENERGY PRODUCTS EQUIPMENT PUMPS, COMPRESSORS & MOTORS BLACKMER PUMPS LGL 2-Inch, 3-Inch and 4-Inch Plant Pumps LGL3021 Pump The LGL3021 pump is based on Blackmer’s standard LGLD3 transfer pump. Whether filling an LPG bobtail or transport – the LGL3021 can do it faster and more efficiently than competitive models. It uses the same internal parts (vanes, liner, seals, bearings, discs and relief valve) as the LGLD3 pump. Differentiating parts are the casing, rotor and shaft, and relief valve cover. The LGL3021 provides similar flow rate and has the same horsepower requirements as the LGLD3 and was designed to provide the same foot-to- flange and flange-to-flange dimensions as competitive pumps. This allows for easy pump installation during change overs or plant maintenance without changing piping or motor drives because the inlet and discharge flanges are on the pump shaft centerline. A major benefit is the LGL3021 has the same horsepower requirement as competitive pumps but provides 13% to 25% more flow, depending upon the LPG installation and application conditions. Pump features include the standard Blackmer design: • Ductile Iron construction • Differential Pressures to 150 psi (10.34 bar) • Patented Cavitation Suppression Liners • Replaceable liner and discs • Maximum Pump Speed: 800 RPM • Sliding Vane, Positive Displacement design for Consistent Performance Applications • Bulk Plant Service • Multiple Cylinder Filling • Vaporizer Feed • Bobtail and Transport Loading & Off-loading • U.L. listed for use on propane, butane, butane/propane mixes and Anhydrous Ammonia(NH3) NEE # Maximum Speed GPM (L/ min) HP (kW) Maximum Differential Pressure Recommended Bypass Valve Setting Relief Valve Setting Maximum Working Pressure LGL3021 800 RPM 112 (424)* 12.1 (9.0) 150 PSI (10.34 bar) 125 PSI (8.6 bar) 150 PSI (10.34 bar) 350 PSI (24.13 bar) * Approximate delivery of propane at 640 RPM at 100 PSI (6.89bar) differential pressure.
