Graco 15D433 Hydraulic Conversion Kit

Graco 15D433 Hydraulic Conversion Kit — Detailed Overview

The Graco 15D433 Hydraulic Conversion Kit lets you convert a pneumatic-driven Graco pump into a Viscount II hydraulic motor system, significantly improving energy efficiency and reducing air consumption.

Key Features & Advantages

• Enables conversion from pneumatic to hydraulic power, leveraging Graco’s Viscount II technology.
• Reuses hydraulic oil, reducing energy consumption compared to pneumatic setups. 
• Delivers continuous, smooth operation – ideal for priming piston pumps used in high‑viscosity applications. 
• Helps achieve significant energy savings, with up to ~80% reduced power cost in some use cases.
• Maintains the same fluid dynamics and pump performance without sacrificing output pressure. 

Typical Applications & Use Cases

The 15D433 kit is especially useful in industrial settings where pumps are currently driven by compressed air, but continuous operation or operational cost is a concern:

• Ink manufacturing or printing – convert ink transfer pumps to hydraulic drive for better efficiency. 
• High-viscosity fluid transfer – enables smoother and more stable delivery, especially in piston pump configurations. 
• Retrofit projects – existing pneumatic systems can be upgraded without replacing the entire pump.

Technical Specifications

Installation Considerations

1. Ensure your existing pneumatic motor is compatible with the Viscount II drive conversion.
2. Mount a hydraulic power pack (oil reservoir + motor) and connect supply / return lines for the oil circuit. 
3. Strip or bypass the pneumatic air supply to the old motor and properly mount the hydraulic motor.
4. Test the system at lower output pressure first to ensure correct hydraulic flow, then ramp up to working conditions.
5. Perform routine inspections of hydraulic fluid levels and check for leaks in the system.

Benefits of Upgrading with 15D433

• Substantially reduces operating costs by eliminating high-volume compressed air use.
• Improves system lifetime by minimizing air motor wear and tear.
• Delivers more stable pumping and consistent pressure output at the fluid section.
• Enables green / energy-efficient upgrades without replacing the entire pump assembly.
