VIVOLO hydraulic pump X3P86, X3P87

Detailed Introduction to VIVOLO (Vivoil) Hydraulic Pumps X3P86 and X3P87
VIVOLO (Vivoil) X3P86 and X3P87 belong to the XV-3P Series high-pressure aluminum alloy external gear pumps. They are unidirectional hydraulic pump products manufactured by Vivoil Oleodinamica Vivolo s.r.l. in Italy, widely used in high-pressure hydraulic systems such as industrial, agricultural, and construction machinery.

Approx. 74
The complete model is usually X3P8702AFEA, etc., where 02 indicates clockwise rotation.

II. Core Technical Parameters

1. General Performance Parameters

  • Material: Aluminum alloy body; cast iron flange version available for some components
  • Maximum Working Pressure: 300-320 bar (approx. 30-32 MPa)
  • Peak Pressure: Up to 320 bar
  • Rated Speed: Maximum 3000 rpm
  • Displacement Range: 14.89-86.87 cm³/rev (overall range of XV-3P Series)
  • Rotation Direction: Unidirectional rotation (left or right rotation optional without replacing the flange)
  • Port Type: BSPP thread port or SAE flange port
  • Shaft Type: Optional tapered 1:8 Woodruff key shaft, parallel key shaft, or spline shaft

2. Fluid Requirements

  • Working Medium: Mineral-based hydraulic oil HLP/HV (complying with DIN 51524 standard)
  • Working Viscosity: 10-100 mm²/s
  • Starting Viscosity: Maximum 1500 mm²/s
  • Filtration Precision: 30-60 microns at the inlet; finer filtration recommended at the outlet

III. Model Code Interpretation (Taking X3P8602AEEA as an Example)

Code Segment
Meaning
X
Unidirectional pump (X = Unidirectional, XM = Bidirectional)
3P

86
Displacement code (corresponding to 70 cm³/rev)
02
Rotation direction (02 = Clockwise, 03 = Counterclockwise)
A
Shaft type (A = Tapered 1:8-ø22 – Key thickness 5mm)
E
Flange type (E = Standard ø50.8mm European flange)
E
Port position (E = Port on the body)
A
Seal type (Standard NBR; Viton/FKM optional for high temperature)

IV. Product Features and Advantages

  1. Patented Design: The XV Series adopts a number of innovative technologies and has obtained 3 patents.
  2. High Pressure Performance: The maximum working pressure can reach 320 bar, suitable for high-pressure hydraulic systems.
  3. Lightweight Design: Aluminum alloy material, light weight, and good heat dissipation performance.
  4. Flexible Installation: The same flange can adapt to left and right rotation without additional components.
  5. Multiple Configurations: Different shaft types, flange types and port positions can be selected to meet different installation needs.
  6. Long Service Life: Precision manufacturing and high-quality materials ensure long-term stable operation.

V. Application Fields

  • Agricultural Machinery: Tractors, harvesters, sprayers, etc.
  • Construction Machinery: Loaders, excavators, cranes, etc.
  • Industrial Equipment: Hydraulic workstations, injection molding machines, presses, etc.
  • Special Vehicles: Fire trucks, sanitation vehicles, aerial work platforms, etc.
  • Other equipment requiring high-pressure hydraulic power

VI. Selection and Ordering Suggestions

  1. Confirm Parameters: Clarify the required displacement, pressure, speed, rotation direction, shaft type and flange type.
  2. Complete Model: Provide the complete model (such as X3P8602AEEA) when ordering to avoid confusion.
  3. Seal Selection: When the temperature is higher than 120°C, it is recommended to select the Viton/FKM seal version.
  4. Accessory Options: Maximum pressure valves, anti-cavitation valves and other accessories can be selected according to needs.
  5. Authorized Channels: It is recommended to purchase through VIVOLO authorized agents to ensure genuine original products and after-sales service.
