Performance for item LGLD4B

At 640 RPM and 100 psi differential pressure, the LGLD4 pump requires 24 bhp (17.9 kW) to handle the rated fluid.

At 800 RPM and 100 psi differential pressure, the LGLD4B pump delivers 330 gpm (1,249 lpm) of the rated fluid.

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.
