Internal Gear Pump, Fixed Displacement (Type PGH) – 13.3 cm³/rev · 模型 177931
This is a gap-compensated internal gear pump from the Bosch Rexroth PGH series, designed for high-pressure industrial applications requiring fatigue-resistant drives with very high numbers of load cycles . The fixed displacement design ensures consistent flow output proportional to drive speed, with high efficiency even at low speeds and viscosities due to its advanced sealing gap compensation . Model Identification (PGH-2X / 013): Code Meaning PGH Internal gear pump 2X Series 20–29 (Frame size 2 or 3) 013 Nominal size: 13.3 cm³ geometric displacement per revolution RE Clockwise rotation (R) with cylindrical shaft (E) 07 SAE flange standard pressure series connection U2 SAE 2-hole mounting flange per ISO 3019-1 V FKM seals (standard for mineral oils) Key Technical Specifications: Parameter Value Displacement (Vg) 13.3 cm³/rev Operating Pressure (continuous) 315 bar Maximum Pressure (intermittent) 350 bar Minimum Drive Speed (n_min) 600 rpm Maximum Drive Speed (n_max) 3000 rpm Theoretical Flow (at 1500 rpm) ~20.0 l/min Weight ~5.0 kg Mounting Type SAE 2-hole flange (U2) or 4-hole flange (E4) Direction of Rotation Clockwise or counterclockwise (specified at order) Shaft End Cylindrical with fitting key per ISO 3019-2 Design & Operating Principle: The pump consists of a housing, internal gear, pinion shaft, plain bearings, axial plates, and a sickle-shaped segment filler element . The hydrodynamically supported pinion shaft drives the internal gear. The segment filler element separates the suction and pressure chambers, while radial compensation elements ensure continuous sealing gap compensation for high volumetric efficiency throughout the pump's service life . Key Features: Feature Benefit Gap-compensated design Maintains high efficiency at low speeds and varying viscosities Low operating noise Quiet operation suitable for noise-sensitive environments Low flow pulsation Smooth flow for sensitive hydraulic circuits Hydrodynamic plain bearings Long service life, no load cycle limitation Broad viscosity and speed range Versatile for multiple applications and fluid types Combination capability Can be combined with axial piston pumps, vane pumps, and other gear pumps Suitable Hydraulic Fluids: Fluid Type Application HLP (Mineral Oil) Standard industrial hydraulics (FKM seals) HEES (Synthetic Ester) Biodegradable, environmentally sensitive areas HFDU (Water-Free) Fire-resistant, high-temperature applications HFC (Water-Glycol) Fire-resistant
