Rexroth PGH5-3X/250RE07VU2 Internal Gear Pump

Overview

The Rexroth PGH5-3X/250RE07VU2 is a frame-size 5, NG 250 internal gear pump with a fixed geometric displacement of 250.50 cm³/rev. This page identifies catalog configuration R901147121 for quotation. Send the complete nameplate and installation details to confirm the required supplied version.

Checking the pressure limit for size 250

The 250 configuration has 250.50 cm³/rev displacement and a maximum operating pressure of 135 bar. Its 170 bar peak rating applies only to the specified brief transient conditions. Confirm this pressure range, the 07 port code, drive power and suction conditions before selecting the unit.

Key configuration details

• 250.50 cm³/rev fixed geometric displacement.
• E shaft: cylindrical keyed shaft.
• U2 mounting: Two-hole flange to ISO 3019-1.
• Material number R901147121 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. Port code 07 means suction and pressure ports to ISO 6162-1. V indicates FKM shaft seal and seals. U2 mounting: Two-hole flange to ISO 3019-1.

Technical specifications

Maximum operating pressure: 135 bar. Peak pressure: 170 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 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 PGH5-3X/250RE07VU2 configuration?

Use material number R901147121 with the full type code. It specifies 250.50 cm³/rev displacement, an E shaft and U2 mounting. Confirm the nameplate, additional suffixes and actual mechanical dimensions before ordering.

Can the 250 size be specified for 315 bar operation?

This catalog configuration has a maximum operating pressure of 135 bar and a brief peak limit of 170 bar. The 315 bar operating limit of smaller PGH5 sizes does not apply to it.

Can I request a quote using PGH5-30/250RE07VU2?

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.
