As part of Shanley's PA-series, the PA040 designation identifies a PA-family screw pump, with the 4B variant depicted in the PA-Series dimension drawings. These pumps are intended as oil-submerged units for hydraulic lift power packs and other hydraulic assemblies, delivering steady, low-pulsation flow in demanding environments. Common fluids pumped include lube oil, hydraulic oil, dielectric oil, and fuel oil, making the PA040-4B suitable for lubrication circuits, hydraulic power packs, and related industrial applications. Distributor listings also show PA040-4B0T as a closely related variant within the PA040 family.
