Overview

The Rexroth PGH4-3X/050LE11VU2 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 R901283011 for quotation. Send the complete nameplate and installation details to confirm the required supplied version.

Checking 050 rotation and pressure limits

The 050 LE version has 50.70 cm³/rev displacement and counterclockwise rotation viewed at the shaft end. Maximum operating pressure is 280 bar; 315 bar is only the brief peak limit. Verify the E25M keyed coupling, 101-2 flange and port arrangement together with the drive direction.

Key configuration details

50.70 cm³/rev fixed geometric displacement.
Counterclockwise rotation, viewed at the shaft end.
E shaft: cylindrical keyed shaft with through-drive to ISO 3019-2, E25M.
U2 mounting: Two-hole flange to ISO 3019-1, 101-2.
Material number R901283011 for catalog identification.

3X denotes the component series family. The first L after the size code means counterclockwise rotation viewed at the shaft end. The next letter, E, specifies a cylindrical keyed shaft with through-drive to ISO 3019-2, E25M. 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 counterclockwise rotation, the E 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.

Frequently asked questions

What identifies the PGH4-3X/050LE11VU2 configuration?

Use material number R901283011 with the full type code. It specifies 50.70 cm³/rev displacement, an E shaft and U2 mounting. Confirm the nameplate, additional suffixes and actual mechanical dimensions before ordering.

Can this L version replace an R version?

L specifies counterclockwise rotation and R specifies clockwise rotation, viewed at the shaft end. Confirm the drive direction, suction and pressure port arrangement, and complete pump configuration. These versions are not automatically interchangeable.

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.

How should I identify the required supplied version?

Send the full catalog type code, material number and a clear nameplate photograph. Confirm the actual supplied version, additional suffixes and installation dimensions 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.
