Blackmer® SGL high-speed pumps, which are part of the Cavitation Line of sliding vane pumps designed for high vapor pressure liquids, 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. In addition, these pumps feature cavitation suppression liners to reduce noise, vibration and wear.
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. SGL pumps are available in 1.25- and 1.5-inch sizes.
