SGL 2-4 Inch Sliding Vane Pumps

SGL 2-4 Inch Sliding Vane Pumps

Ductile-Iron Pump for Liquefied Gas Transfer Applications

Blackmer® SGL pumps, which are part of the Cavitation Line of sliding vane pumps, are designed for the liquid transfer or recirculation of refrigerants and other liquefied gasses. Constructed of shock-resistant ductile iron and available with a wide variety of seal materials, SGL pumps are ideally suited 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 condition. In addition, SGL pumps feature a cavitation suppression liner designed for reducing the noise, vibration, and wear normally caused by entrained vapors.SGL pumps are available in 2-, 3- and 4-inch sizes. Available options include a double mechanical seal.

Features and Benefits

• Cavitation suppression liner design for reducing the noise, vibration, and wear normally caused by entrained vapors
• Replaceable casing, liners and end discs allow easy rebuilding of the pumping chamber to like-new condition
• Mechanical seal and elastomer options assure compatibility with refrigerants and other specialty gases
• Available in 2-, 3- and 4-inch sizes
• Ductile-iron construction with internal relief valve
