The Rexroth gear pump from Rexroth adopts the principle of gear internal meshing, where the inner and outer gear pitch circles are closely adjacent to one side, and the other side is separated by a "crescent plate" on the pump cover. The active internal gear on the main shaft drives the external gear to rotate in the same direction. At the inlet, the gears separate from each other to form negative pressure and suck in liquid. At the outlet, the gears continuously engage and squeeze out the liquid. Due to its unique structure, it is particularly suitable for conveying media with high viscosity, with a viscosity range of 0.2-cp. It can be conveyed in reverse as long as the motor direction is changed; The Rexroth internal meshing pump body can be turned, and the inlet and outlet positions are at right angles, making it easy to select the inlet and outlet positions; Rexroth gear pumps he convenient interfaces for connecting insulation or cooling media between the pump body, end cover, and bearing seat. REXROTH meshing has the advantages of no trapped oil phenomenon, smooth transportation, high efficiency, low noise, and long service life. Internal gear pumps are suitable for transporting Newtonian or non Newtonian liquids in industries such as petroleum, chemical, coating, dye, food, oil, and medicine. The types of liquids transported can range from light and volatile liquids to hey, viscous, and even semi-solid liquids.
The Rexroth hydraulic pump PGH type is a clearance compensated internal gear pump with a constant discharge volume. The active gear shaft, which is placed in a hydrodynamic manner, drives the hollow wheel with internal meshing. The backlash space opened between the active gear shaft and the hollow wheel in the oil suction area sucks in hydraulic fluid and delivers it to the oil pressure area. The oil suction area and the oil pressure area are separated by radial compensation components and the engagement between the hollow wheel and the driving gear shaft.
Rexroth internal gear pump: specifications 1.7 to 40; Low operating noise, minimal vibration, and compensated sealing clearance enable efficient operation even at low viscosity Suitable for various speeds and viscosity ranges Can provide axial pumps/can be used in combination with axial piston pumps and vane pumps
