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.
