As part of the Cavitation Line, LG1 Series Motor Sliding Vane Pumps feature a 1-in port and have long been popular as a propane transfer pump for cylinder filling, small volume motor fueling and supplying small vaporizers. They offer the same heavy-duty construction of larger Blackmer rotary vane pump models and are available in two mounting styles and capacity ranges, and are built exclusively for propane, LPG, butane, and anhydrous ammonia.
