Rexroth A10VSO45LA7DG Variable Axial Piston Pump

The Rexroth A10VSO45LA7DG is a variable axial piston pump for open-circuit hydraulic systems. This page covers the size 45 LA7DG model with Series 32 catalog reference data. DENGFENG accepts inquiries for original Rexroth products and confirms the exact configuration, condition and availability for each quotation.

A complete size 45 LA7DG inquiry

The size 45 LA7DG option combines power control with a remotely controlled pressure cut-off. Send photographs of the controller and pilot connections with the complete pump identification. Retain the LA7DG code when describing the installed unit and define the required external valve supply scope.

Key features

• Size 45 with LA7DG power control with remote pressure cut-off
• Series 32 catalog reference
• Maximum geometric displacement: 45 cm³/rev
• Nominal pressure: 280 bar (catalog reference)
• Original Rexroth product inquiry; exact unit confirmed in the quotation

Controller function

LA7DG combines power control with a remotely controlled pressure cut-off using a separate external pressure relief valve. LA7 identifies a power-control start range of 91 to 160 bar. Specify the required power characteristic at the drive speed and the remote cut-off circuit. The external pressure relief valve is quoted separately. LA7DG does not include the DS flow-control function.

Model and configuration

Reference values apply to Series 32, with rotary group version E as covered by the reviewed technical table. Confirm the full suffix, applicable fluid and supplied version before applying these values to an individual unit.

Maximum pressure is not a continuous-duty setting. Confirm the applicable operating limits for the exact supplied unit.

How to check the fit

• Keep the full LA7DG designation and identify the remote pressure valve, pilot connections and requested power characteristic.
• Compare the rotation, shaft, mounting flange, ports, seals and through-drive option with the installed unit.
• Check the hydraulic circuit, operating conditions and exact unit specifications before ordering.

Frequently asked questions

Is A10VSO45LA7DG a complete ordering code?

No. It identifies a size and controller combination. Send the full nameplate code, including the series and all suffixes, so the exact configuration can be quoted.

Are price and stock shown on this page?

Price, condition, availability and delivery are confirmed individually after the complete model and quantity are reviewed.

Does LA7 specify a fixed motor power?

No. The category identifies the beginning-of-power-control range. Specify the required power characteristic with the operating speed and confirm the quoted factory setting.

Does the quotation include the remote pressure relief valve?

The external valve is a separate item. Identify the required valve and pilot circuit so its supply scope can be stated in the quotation.

Can LA7DG be treated as LA7DS or DG?

These control designations identify different functions. LA7DG combines power control and remote pressure cut-off; LA7DS adds pressure cut-off and flow control to power control. DG alone identifies two-point displacement control. Retain the complete controller code.
