Description: Features Product Description Type Codes Pub Technical Data Diagram Characteristic Schematics Dimensions Planning Instruction Fixed displacement Low operating noise Low flow pulsation High efficiency also at low viscosity due to sealing gap compensation Long service life due to plain bearings and sealing gap compensation Suitable for broad viscosity and speed ranges Very good suction characteristic All frame sizes and sizes can be combined with each other Can be combined with internal gear pumps PGH, vane pumps PV7 and axial piston pumps Integrated valve technology in the connection cover possible upon request For drives in the minor and medium performance and pressure range in industrial applications, e.g. machine tools With high operating pressure for fatigue-resistant drives in mobile applications, for example lifting equipment, fans and spreaders Read More Read Less Set-up Hydraulic pumps of type PGF are leakage gap-compensated internal gear pumps with constant displacement. They basically comprise of housing (1), bearing cover (1.1), end cover (1.2), internal gear (2), pinion shaft (3), plain bearings (4), axial washers (5) and stop pin (6), as well as the segment filler element (7) consisting of segment (7.1), segment support (7.2) and the seal rolls (7.3). Suction and displacement procedure The hydrodynamically supported pinion shaft (3) drives the internally geared internal gear (2) in the displayed direction of rotation. During the rotation, there is a volume increase over an angle of approx. 180° in the suction range. An underpressure results and fluid flows into the chambers. The sickle-shaped segment filler element (7) separates suction and pressure chamber. In the pressure chamber, the teeth of the pinion shaft (3) engage in the space between the teeth of the internal gear (2) again. The liquid is displaced via the pressure channel (P). Axial compensation The axial compensation force FA takes effect in the area of the pressure chamber and is generated with the pressure field (8) in the axial washers (5). So the axial longitudinal gaps between the rotating and the fixed parts are extraordinarily small and ensure perfect axial sealing of the pressure chamber. Radial compensation The radial compensation force FR acts on segment (7.1) and segment support (7.2). The area ratios and the position of the sheet seals (7.3) between the segment and segment support are designed so that an almost leakage gap-free sealing between internal gear (2), segment filler element (7) and pinion shaft (3) is achieved. Spring elements under the sheet seal (7.3) ensure sufficient contact pressure, also with very low pressures. Hydrodynamic and hydrostatic mounting The forces acting on the pinion shaft (3) are accepted by hydrodynamically lubricated radial plain bearings (4); the forces acting on the internal gear (2) by the hydrostatic bearing (9). Gear tooth system The gear tooth system is an involute tooth system. Its large meshing length results in little flow and pressure pulsation; these little pulsation rates considerably contribute to the low-noise running.
