Rexroth PGH5-3X/125RE11VE4 Internal Gear Pump

Overview

The Rexroth PGH5-3X/125RE11VE4 is a frame-size 5, NG 125 internal gear pump with a fixed geometric displacement of 125.30 cm³/rev. This page identifies catalog configuration R901147125 for quotation. Send the complete nameplate and installation details to confirm the required supplied version.

Specifying the 125 E4 installation

The size 125 version has 125.30 cm³/rev displacement and the 160B4SW four-hole flange. Provide the motor rating, normal drive speed and required flow together with the mounting dimensions. Check the E40N keyed coupling and available installation space before ordering.

Key configuration details

• 125.30 cm³/rev fixed geometric displacement.
• E shaft: cylindrical keyed shaft with through-drive to ISO 3019-2, E40N.
• E4 mounting: Four-hole flange to ISO 3019-2, 160B4SW.
• Material number R901147125 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, E, specifies a cylindrical keyed shaft with through-drive to ISO 3019-2, E40N. 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. E4 mounting: Four-hole flange to ISO 3019-2, 160B4SW.

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 clockwise rotation, the E shaft, coupling and E4 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 PGH5-3X/125RE11VE4 configuration?

Use material number R901147125 with the full type code. It specifies 125.30 cm³/rev displacement, an E shaft and E4 mounting. Confirm the nameplate, additional suffixes and actual mechanical dimensions before ordering.

Is the E4 flange the same as U2?

E4 uses four mounting holes under ISO 3019-2. U2 uses a two-hole flange under ISO 3019-1. Verify the pilot, bolt pattern, shaft and coupling alignment before considering a change.

Can I request a quote using PGH5-30/125RE11VE4?

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.
