Item Overview for Blackmer LGLD4B
The Blackmer LGLD4B is a sliding vane pump built in ductile iron construction for bulk plant service, multiple cylinder filling applications, vaporizers, bobtails, and transports. Containment comes from mechanical seals backed by Buna-N elastomers, a combination chosen for punishing liquids. Weld flanges speed connection during commissioning and later service. Overpressure protection arrives built in, with a corrosion-resistant relief valve shielding the casing and downstream piping. Supplied as a bare unit, it drops into an existing drive arrangement or a purpose-built skid. It also brings a cavitation suppression liner that curbs noise, vibration, and vapor-related wear, UL listing for propane, butane, and anhydrous ammonia service, and pre-engineered Integrated Unit Assemblies for drop-in installation. As part of the LGL lineup, it shares parts and service procedures with the rest of the range. Capacity extends to 370 GPM, shortening load and unload cycles.
