Product Description

The Rexroth A4VG90HD1D1/32L-NSF02F001P is a high-performance variable displacement axial piston pump from the Bosch Rexroth A4VG Series 32.

The A4VG platform is designed for closed-circuit hydrostatic drives, where hydraulic flow is circulated between the pump and hydraulic motor. Bosch Rexroth describes the A4VG as a closed-circuit pump platform used in demanding mobile hydraulic and hydrostatic drive applications. (Bosch Rexroth Global)

The A4VG90 configuration can be used in hydraulic systems requiring controlled variable displacement and high-pressure hydraulic power transmission.

Suitable for replacement, repair, maintenance and OEM applications, subject to verification of the complete ordering code and machine requirements.

Key Features

• Bosch Rexroth A4VG Series 32

• Variable displacement axial piston design

• Swashplate construction

• Designed for closed-circuit hydraulic systems

• Nominal size 90

• HD hydraulic proportional control configuration

• High-pressure hydraulic pump platform

• Suitable for hydrostatic drive applications

• Suitable for mobile and industrial hydraulic equipment

• Available for OEM replacement and maintenance applications

For the Series 32 platform, Bosch Rexroth documentation lists HD as proportional hydraulic control related to pilot pressure. (Bosch Rexroth Russia)

Verified Specifications

The following specifications can be supported by available documentation:

Specification	Verified Information
Pump type	Variable axial piston pump
Series	A4VG Series 32
Nominal size	90
Circuit	Closed circuit
Design	Swashplate
Nominal pressure	400 bar
Maximum pressure	450 bar
Control	HD
Version	Metric

The A4VG Series 32 documentation specifies 400 bar nominal pressure and 450 bar maximum pressure for the platform. (DBR Automation)

Important: These are series-level specifications. For purchasing or replacement, the complete ordering code A4VG90HD1D1/32L-NSF02F001P should be matched against the manufacturer's documentation/nameplate. Do not substitute another A4VG90 configuration simply because the nominal size is the same.

Applications

The Rexroth A4VG90 hydraulic piston pump can be used in applications such as:

• Construction machinery

• Mobile hydraulic equipment

• Hydrostatic transmission systems

• Excavators and loaders

• Mining machinery

• Agricultural machinery

• Material-handling equipment

• Industrial hydraulic systems

• OEM machinery

• Heavy-duty hydraulic drives

FAQ

What is A4VG90HD1D1/32L-NSF02F001P?
