VIVOLO gear pump X3P66, X3P68 product description
VIVOLO X3P66 and X3P68 are high-performance external gear pumps belonging to the Group 3 pump series, proudly manufactured in Italy by Vivoil—a world-renowned brand specializing in hydraulic components since 1985. With a focus on reliability, flexibility, and premium quality, these two models are engineered to deliver stable and efficient hydraulic power for a wide range of industrial applications, featuring precision craftsmanship and rigorous quality control through manual assembly and testing.
Product Overview
Both X3P66 and X3P68 gear pumps adopt a compact and robust design, characterized by aluminum construction with external gears and a standard ø50.8 flange configuration. They are available as unidirectional pumps (with optional clockwise or counterclockwise rotation) and can be equipped with various shaft options, including 1:8 tapered shaft, SAE-2 bolt, keyed or splined shaft, to meet diverse installation requirements. These pumps are designed to operate in harsh industrial environments, offering excellent resistance to wear and long service life.
Core Features
-
Premium Italian Craftsmanship: Each pump is manually assembled and tested at Vivoil’s Italian factory, using 5-axis machining and single-handle processing for high-precision components, ensuring consistent performance and reliability.
-
High Pressure Capacity: Both models can withstand a maximum working pressure of 300 bar and a peak pressure of 320 bar, making them suitable for high-demand hydraulic systems.
-
Flexible Configuration: Optional NBR or Viton seal kits are available to adapt to different hydraulic media and operating conditions. A maximum pressure valve and high-pressure shaft seal (25 bar, 1500 rpm) can also be selected based on specific needs.
-
Efficient Operation: The optimized gear design minimizes internal leakage, improves volumetric efficiency, and reduces energy consumption, ensuring stable fluid delivery even at varying speeds.
-
Compact & Durable: The aluminum body structure balances light weight and mechanical strength, while the precision-machined gears and bearings enhance wear resistance and extend the pump’s service life.

Installation & Maintenance Notes
-
Installation: Ensure the pump is mounted securely with the correct flange and shaft connection to avoid vibration during operation. The suction and pressure ports should be connected tightly to prevent oil leakage.
-
Hydraulic Medium: Use clean hydraulic oil that meets the specified viscosity requirements to avoid clogging or wear of internal components. Regularly check the oil quality and replace it as needed.
-
Maintenance: Periodically inspect the seals, gears, and bearings for wear or damage. Replace worn parts in a timely manner to maintain the pump’s performance. Keep the pump clean to prevent debris from entering the hydraulic system.
-
Operation: Do not exceed the maximum working pressure and rotational speed to avoid damaging the pump. Start the pump gradually and check for abnormal noise or leakage before formal operation.
