X1P3102FBBA Vivoil Hydraulic Gear Pump 5.85cc

Product Overview

The X1P3102FBBA is a Vivoil / Vivolo XV-1P Group 1 unidirectional external gear pump configured with a standard European Ø25.4 mm flange, 1:8 tapered shaft, and 3/8″ BSPP inlet and outlet connections.

According to the official Vivoil XP105 technical data sheet, the X1P3102FBBA corresponds to the XV-1P/5.9 displacement class with an actual geometric displacement of 5.85 cm³/rev. Its maximum working pressure is 250 bar, while the maximum peak pressure is 300 bar.

The Vivoil product page identifies the XV-1P Group 1 platform as an aluminium external gear pump range covering approximately 0.91 to 9.88 cm³/rev, with rotational speeds up to 6000 rpm, depending on configuration and operating conditions.

The X1P3102FBBA is a fixed-displacement mechanical gear pump, making it suitable for compact hydraulic power units, mobile equipment, industrial auxiliary circuits, lubrication systems and general hydraulic applications.

For replacement projects, engineering compatibility should be verified against the complete configuration code rather than the displacement code alone. Our replacement solution focuses on in-place dimensional and functional interchangeability, with 100% simulated operating-condition testing covering key operating parameters before shipment.

Key Technical Advantages

1. Precise 5.85 cm³/rev Fixed Displacement

The X1P3102FBBA provides a geometric displacement of 5.85 cm³/rev, making it suitable for hydraulic systems requiring repeatable fixed-flow delivery. The fixed-displacement architecture eliminates the complexity of a variable displacement mechanism and supports a compact mechanical design.

2. 250 bar Working Pressure Capability

The official XP105 data sheet specifies 250 bar maximum working pressure and 300 bar maximum peak pressure for the 5.85 cm³/rev configuration. This makes the pump suitable for relatively demanding Group 1 hydraulic applications, provided continuous operating conditions remain within the rated working limit.

3. Lightweight Aluminium Construction

The XV-1P platform is designed as an aluminium external gear pump. The lightweight housing is particularly advantageous for compact mobile machinery and power units where overall system mass and installation space are important design constraints.

4. Standard Ø25.4 mm European Mounting Interface

The Ø25.4 mm European flange and 71.9 × 52.4 mm mounting geometry provide a defined mechanical interface. For replacement applications, maintaining this interface is essential for achieving practical installation interchangeability.

5. Defined Shaft Torque Limit

The standard 1:8 tapered shaft has an admissible torque rating of 43 Nm. This value should be included in the engineering verification whenever the pump is used under high pressure, high speed or high transient-load conditions.

6. Flexible Group 1 Platform

The Vivoil XV-1P Group 1 family covers approximately 0.91–9.88 cm³/rev, with speeds up to 6000 rpm, while offering multiple shaft, seal, port and pressure configurations. This makes the platform adaptable to a wide range of compact hydraulic applications.

Application Areas

Typical applications for the X1P3102FBBA include:

• Compact hydraulic power units
• Mobile hydraulic equipment
• Agricultural machinery
• Small construction machinery
• Material-handling equipment
• Hydraulic lifting systems
• Auxiliary hydraulic circuits
• Industrial automation equipment
• Hydraulic lubrication systems
• Oil circulation systems
• Hydraulic test equipment
• Compact industrial machinery

Final application suitability should always be verified against operating pressure, speed, fluid viscosity, temperature, input torque and duty cycle.

Expert Maintenance Tips

1. Verify Rotation Before Commissioning

The X1P3102FBBA uses the 02 right-rotation configuration. Motor or PTO rotation should be verified before full-load operation.

2. Check Drive-Shaft Torque

The official permissible shaft torque is 43 Nm for this shaft configuration. Actual pump input torque should be calculated under the intended pressure and speed conditions and kept within the specified mechanical limit.

3. Minimize Suction-Line Losses

Use an adequately sized suction line and prevent excessive restriction from undersized piping, sharp bends, clogged filters or excessive oil viscosity. Proper inlet conditions are essential for maintaining stable gear-mesh filling and minimizing cavitation risk.

4. Distinguish Working Pressure from Peak Pressure

The official data sheet specifies 250 bar as maximum working pressure and 300 bar as maximum peak pressure. The 300 bar value should not be interpreted as a continuous operating rating.

5. Maintain Hydraulic Fluid Cleanliness

Contamination control should be treated as a primary maintenance requirement for external gear pumps. Inspect suction and return filtration regularly, especially after component failure, hose replacement or initial system commissioning.

6. Match the Complete Part Number During Replacement

For true drop-in replacement, verify the complete X1P3102FBBA configuration, including:

5.85 cm³/rev displacement + right rotation + Ø25.4 mm flange + 1:8 tapered shaft + 3/8″ BSPP ports + standard cover.

This complete-code approach is essential for achieving reliable in-place interchangeability.
