PVG-100-F1UV-RGFY-C-ERFSN-1415 Oilgear Open Loop Axial Piston Pump 100cc

Product Overview

The Oilgear PVG Series is an open-loop, variable-displacement axial-piston pump platform designed for high-pressure hydraulic applications requiring fast response, compact packaging and reliable operation under demanding working conditions. Oilgear documentation identifies the PVG range as an open-loop axial-piston platform with strong contamination tolerance, high-pressure capability and suitability for low-viscosity hydraulic fluids.

This product group covers the following configurations:

• PVG-100-F1UV-RGFY-C-ERFSN-1415
• PVG-130-C2UV-RGFK-P
• PVG-075-F1UV-LSFY-P-1NNNN

For the PVG-130 configuration, the P control designation is officially identified as Pressure Compensating. The PVG-075 full ordering code can also be decoded using Oilgear’s published ordering information. The complete C-ERFSN-1415 suffix on the PVG-100 configuration is not fully represented in Oilgear’s current public standard ordering chart, so its exact control configuration should be verified against the pump nameplate, order confirmation or installation drawing rather than inferred.

For aftermarket or equivalent replacement applications, the key engineering objective is mechanical and functional interchangeability: mounting, shaft, rotation, port arrangement and control configuration must be matched before replacement. Our replacement program can additionally apply 100% simulated working-condition testing to verify assembly quality and operating behavior before shipment.

Key Technical Advantages

1. Hard-On-Hard Rotating System

Oilgear’s PVG design uses hardened working surfaces in the rotating group. Hardened piston shoes and the swashblock interface are designed to improve contamination resistance, wear resistance and high-pressure durability.

2. Hydrodynamic Barrel Support

A proprietary hydrodynamic bearing supports the cylinder barrel, contributing to the compact architecture and long-life operating concept of the PVG design.

3. Hardened Cylinder and Valve-Plate Construction

The PVG platform uses hardened cylinder and valve-plate working surfaces together with hardened modular iron construction. This architecture is intended to improve durability in contaminated or demanding hydraulic environments.

4. Pressure-Lubricated Bearing Arrangement

Oilgear specifies pressure-lubricated bearing arrangements intended to support long service life during high-pressure, high-cycle operation.

5. Fast Control Response

The PVG is designed around a high-response, four-way pilot-operated control architecture, allowing rapid displacement response to changing hydraulic system demand.

6. Low-Viscosity and Contamination Tolerance

The manufacturer specifically highlights low-viscosity-fluid capability and contamination resistance, making the PVG platform suitable for demanding industrial environments where hydraulic cleanliness and fluid characteristics can strongly affect pump life.

7. Field Interchangeability

Oilgear’s PVG sales literature identifies field interchangeability as a product advantage. For an aftermarket replacement unit, this principle should be implemented by matching mounting, shaft, rotation, porting and control configuration rather than relying on the frame designation alone.

Application Areas

Typical applications for the PVG family include:

• Forging presses
• Extrusion presses
• Large off-highway construction equipment
• Material handling systems
• Automotive hydraulic machinery
• Aerospace hydraulic systems
• High-power industrial hydraulic power units

These application areas are consistent with Oilgear’s published PVG family positioning and application information.

For aftermarket replacement projects, the PVG series is particularly relevant where the customer needs to restore an existing hydraulic system without redesigning the complete pump mounting, drive and piping architecture.

Expert Maintenance Tips

• Verify rotation before startup. Clockwise and counterclockwise configurations must be driven in the corresponding direction shown on the pump housing.
• Keep the inlet unrestricted. Oilgear recommends an inlet velocity below 5 ft/s / 1.5 m/s and a low-restriction suction line with minimal fittings.
• Do not install an inlet strainer. This is specifically stated in the Oilgear PVG service instructions.
• Keep case pressure below 25 psi / 1.7 bar. The case-drain line should be unrestricted, full-size and independently connected to the reservoir below the minimum fluid level.
• Maintain shaft alignment. Oilgear specifies a maximum shaft misalignment of 0.005 in / 0.13 mm TIR.
• Avoid extended zero-delivery operation without proper supercharge. Long periods at neutral may damage the pump under unsuitable circuit conditions.
• Control hydraulic contamination. Use appropriate pressure- or return-line filtration and replace filter elements according to the contamination indicator and service requirements.

Engineering Verification Note

For a production website, the safest SEO positioning is Oilgear PVG, not Rexroth/Parker/Danfoss. The official Oilgear documents verify the PVG-075, PVG-100 and PVG-130 performance classes and ordering architecture. The first two full codes supplied here contain legacy or non-standard portions that are not completely decoded by the current public ordering guide, so those segments should remain exactly as supplied rather than being “translated” into unsupported control claims.

This distinction is especially important for B2B buyers comparing replacement pumps by displacement, pressure class, maximum speed, shaft, rotation, porting and control configuration.
