Available in five sizes with capacities of 4 to 300 gpm (15-1,135 L/min), constructed of shock-resistant ductile iron and available with a wide variety of seal materials, an SGL pump is the pump to use for almost any liquefied gas application. The sliding vane, positive displacement design provides excellent priming capability and high performance over a wide range of temperatures and differential pressures. The vanes self-adjust as they wear, maintaining the efficiency of a new pump. The vanes, liner and end discs are all easily replaced, bringing the pump back to like-new specifications. Replaceable casing liner and end discs Blackmer SGL models can be economically rebuilt for like-new performance with replaceable end discs and liners, specially designed to suppress cavitation and reduce wear. Two-piece threaded lock collars 1 Precisely position the rotor and shaft, allowing the pump to operate under high inlet pressures. In addition, this positive lock thrust control helps prevent premature wear to internal components. Ductile iron construction All pressure parts are of ductile iron for greater resistance to both thermal and mechanical shock. Internal relief valve Protects the pump from excessive pressure buildup in the event of an obstructed or closed return line. Nonmetallic Duravanes Designed to resist wear under non-lubricating conditions. These chemically inert vanes are formulated of a tough resin material for long life and quiet operation. Blackmer mechanical seals Specially developed for non-lubricating liquids, Blackmer's exclusive component type design is field proven to provide long life and reliable service on a wide range of liquefied gas applications. External ball bearings - Low friction grease-lubricated ball bearings are completely isolated from the pumpage by mechanical seals for trouble-free service and long life.
