Product Overview

PVQ40AR08AA10H211100A100100CD0A is a Vickers by Danfoss PVQ Series open-circuit variable displacement axial piston pump. PVQ pumps use an in-line axial piston architecture with pressure and/or flow compensator controls. Danfoss highlights the series for low operating noise, flexible control configurations and industrial service.

The H configuration is a Load Sensing and Pressure Limiter Compensator Control. It automatically adjusts pump flow in response to a remote load-sensing pressure signal and reduces displacement when the preset maximum operating pressure is reached. The standard load-sense differential is 11 bar, with a bleed-down orifice for low-pressure standby.

For replacement applications, full model-code verification is essential because the code identifies displacement, rotation, mounting, shaft, ports, seals, pressure setting and control functions.

Key Technical Advantages

Load-Sensing and Pressure-Limiter Control

The H control combines load-sensing flow management with maximum-pressure limiting. This allows the pump to respond to machine demand instead of continuously delivering maximum displacement and provides pressure-limiting action at the upper operating boundary.

Low-Noise Timing Architecture

Danfoss states that PVQ pumps use a patented timing arrangement that reduces outlet pressure pulses and the tendency of the hydraulic system to generate noise. The current PVQ product family continues to identify low sound level as a core characteristic.

Industrial 1800 rpm / 210 bar Platform

The PVQ40 is rated at 1800 rpm and 210 bar, with 27.6 kW input power at maximum pressure and rated speed.

Full-Code Configuration Control

The complete ordering code defines the mechanical and hydraulic configuration of the pump. This is particularly important for replacement projects because a nominal-size match alone does not guarantee interface compatibility.

Material / Manufacturing Note

The reviewed official documentation does not publish specific steel grades or heat-treatment specifications for this exact configuration. Therefore, specific material claims are intentionally omitted. Engineering performance should instead be discussed around precision piston-group assembly, compensator response, sealing, lubrication and contamination control.

Application Areas

Danfoss lists PVQ applications including:

• Injection molding machines
• Metal forming equipment
• Metal cutting machinery
• Conveyor lines
• Mining machinery
• Oil and gas equipment
• Primary metals machinery
• Industrial hydraulic systems

Expert Maintenance Tips

• Fill the pump case through the uppermost drain port before start-up.
• Keep the case-drain circuit unrestricted and return it to the reservoir below the oil level. Maximum case pressure is 0.35 bar.
• For systems operating between 70 and 210 bar, the official cleanliness recommendation for variable piston pumps is ISO 4406 17/15/13 under the stated standard conditions.
• Maintain hydraulic-fluid viscosity within the recommended operating envelope; Danfoss identifies approximately 16–40 cSt as the optimum viscosity range.
• During replacement, verify the complete model code, shaft alignment, port configuration, load-sense circuit and pressure setting before commissioning.
• For your replacement program, 100% simulated working-condition testing can be used to validate pressure response, load-sensing behavior, flow output and installation compatibility before shipment.
