Rexroth PGH4-3X/040LE11VU2 Internal Gear Pump

Overview

The Rexroth PGH4-3X/040LE11VU2 is a frame-size 4, NG 40 internal gear pump with a fixed geometric displacement of 40.10 cm³/rev. This page identifies catalog configuration R901283010 for quotation. Send the complete nameplate and installation details to confirm the required supplied version.

Confirming the 040 counterclockwise version

This 40.10 cm³/rev version rotates counterclockwise when viewed at the shaft end. It uses an E25M keyed shaft and a 101-2 two-hole flange. Confirm rotation, suction and pressure connections, and the complete nameplate before ordering. Do not treat the clockwise 040 RE configuration as an interchangeable reference.

Key configuration details

• 40.10 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 R901283010 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.

Technical specifications

Maximum operating pressure: 315 bar. Peak pressure: 350 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.
