Gear pumps are extremely simple and reliable, engineered by Bosch Rexroth to deliver the reliable hydraulics performance today’s manufacturers and OEMs demand. Depending on the number of teeth, the “idler” gear might be driven directly by the “drive” gear. The teeth on Gear Pumps can be spur (straight), helical (slanted), herringbone, etc. Rexroth offers multiple gear pump models and variations, all exhibiting different effects on the efficiency, strength, smoothness and other areas of hydraulics system operation. Two pairs of valves can be added to make this a Reversing Gear Pump, which pumps in the same direction regardless of which direction the gears rotate.
Fixed displacement gear pumps are the most common hydraulic component. Simple in design, with few moving parts, Rexroth has designed these gear pumps to meet the rigors of industrial use.
