The Bosch Rexroth PGH4-3X/020RR11VU2-A516 (R901423298) is a high-performance hydraulic internal gear pump known for its gap-compensation and constant displacement capabilities. This pump is engineered to deliver efficient and reliable performance with a fixed displacement, ensuring minimal flow and pressure pulsation, which contributes to its low operating noise level. The design includes a robust mounting flange, housing, cover with through-drive, pinion shaft, internal gear, plain bearings, axial washers, and stop pin. Its advanced radial compensation system comprises segments, segment support, and seal rolls that automatically adjust clearances to maintain high volumetric efficiency throughout the pump's operational life. Additionally, the axial compensation is achieved through axial washers that are balanced by pressure fields to provide optimal sealing with reduced mechanical losses. The PGH4-3X/020RR11VU2-A516 features hydrodynamic and hydrostatic mounting for the pinion shaft and internal gear respectively. This ensures smooth operation even at low speeds and when handling fluids of varying viscosities. The involute edge gear tooth system enhances meshing length which further reduces noise levels during operation. This pump is suitable for a wide range of applications requiring fatigue-resistant drives capable of delivering high power and operating under high pressures over numerous load cycles. Typical uses include plastic processing machines, presses that can be automated, casting machines, and systems involving accumulator charging operations. Its versatility allows it to be combined with other pumps such as axial piston pumps or vane pumps and it's compatible with HFC fluid seal designs. The PGH4-3X/020RR11VU2-A516 maintains high efficiency across broad viscosity and speed ranges making it an adaptable solution for various hydraulic requirements.
