Overview

The Rexroth PGH4-3X/050RR11VU2 is a frame-size 4, NG 50 internal gear pump with a fixed geometric displacement of 50.70 cm³/rev. This page identifies catalog configuration R901147114 for quotation. Send the complete nameplate and installation details to confirm the required supplied version.

Checking size 050 pressure and spline

This 50.70 cm³/rev splined-shaft configuration is cataloged for central and rear positions in pump combinations. Maximum operating pressure is 280 bar, with a brief peak limit of 315 bar. Check the pressure cycle, 15-tooth coupling and permissible transmitted torque for the complete assembly.

Key configuration details

50.70 cm³/rev fixed geometric displacement.
R shaft: splined shaft with through-drive to ISO 3019-1 (25-4, 15T, 16/32DP).
U2 mounting: Two-hole flange to ISO 3019-1, 101-2.
Material number R901147114 for catalog identification.

3X denotes the component series family. The first R after the size code means clockwise rotation viewed at the shaft end. The next letter, R, specifies a splined shaft with through-drive to ISO 3019-1 (25-4, 15T, 16/32DP). Port code 11 means a pressure port to ISO 6162-2, with suction port to ISO 6162-1. V indicates FKM shaft seal and seals. U2 mounting: Two-hole flange to ISO 3019-1, 101-2.

Maximum operating pressure: 280 bar. Peak pressure: 315 bar, limited to 10 ms per event and 300 hours total accumulated peak duration. Reference measurements use HLP46 at 50°C and approximately 30 mm²/s. Confirm the limits for the actual fluid and duty; these values are not recommended system settings.

Catalog speed range: 400–3000 rpm. Permissible speed depends on pressure, drive power, oil viscosity and inlet conditions; confirm the operating point before ordering.

Check the installation

Match the complete nameplate, material number and any additional suffixes.
Confirm clockwise rotation, the R shaft, coupling and U2 mounting dimensions.
Verify the pressure and suction port sizes, flange pattern and installation orientation.
Provide normal and peak pressure, speed, fluid type, viscosity and inlet conditions.
Confirm the central or rear position in the pump combination, adapter details and permissible through-drive torque.

Frequently asked questions

What identifies the PGH4-3X/050RR11VU2 configuration?

Use material number R901147114 with the full type code. It specifies 50.70 cm³/rev displacement, an R shaft and U2 mounting. Confirm the nameplate, additional suffixes and actual mechanical dimensions before ordering.

What pressure limit applies to this size?

The maximum operating pressure is 280 bar. The 315 bar peak limit is only for the specified brief transient conditions. Do not apply the 315 bar operating rating of other sizes to this configuration.

Do all PGH RR versions use the same spline?

No. This configuration uses 25-4, 15T, 16/32DP, under ISO 3019-1. The first R denotes clockwise rotation and the second R denotes the shaft type. Check the complete spline and mounting specification; the RR letters alone do not define identical dimensions across frame sizes.

Can I request a quote using PGH4-30/050RR11VU2?

Include that reference with a clear nameplate photograph. This page uses the 3X component-series designation; the precise supplied version and its connections will be confirmed in the quotation.

What is needed to confirm price and availability?

Send the complete identification, quantity, destination and required supply condition. Price, stock, delivery time and warranty terms are confirmed in the quotation.
