 Pump Gears

Pump Gears are special gears designed to run together (usually two, sometimes three in a gear train) with minimal clearance between the outer diameter of the gear and the id pocket of the gearbox, and the outer diameter of the gear to the root diameter of its mate(s) when meshed, and both sides of the gear to the gear box. Usually there is no more than about .005" clearance between the outer diameter of the gear and the id pocket of the gear-box, maybe about .005' to .010" clearance between the outer diameter of the gear and the root diameter of its mate when meshed, and about .003" clearance between the sides of the gear and the gear box. Depending on the original manufacturer, these clearances may be more or less. Pump gears can be spurs, helical, or herringbone (with no groove between the teeth). Herringbone pump gears seem to be the most popular. Pump gears can be made from customer-supplied materials, as well as materials provided by Stahl Gear & Machine Co.
