2-in-1 Micro Pump Kit for TOYAN Engines

Water Cooling Conversion & Independent Lubrication Upgrade

Take your model engine project to the next level.

Designed for advanced hobbyists and engine enthusiasts, this compact metal gear pump can be used to build a custom water cooling circulation system or an external independent lubrication system for TOYAN and other miniature internal combustion engines.

Driven by a pulley and belt, the pump can circulate coolant through a custom water-cooling setup or deliver lubricating oil to critical engine components, opening up new possibilities for engine experimentation and performance upgrades.

Why Upgrade Your Engine?

Option 1: Convert Air-Cooled Engines to Water Cooling

Many model engines rely entirely on airflow for cooling. During extended operation or hot weather, cylinder temperatures can rise significantly.

By combining this pump with a water-cooled cylinder jacket, radiator, and reservoir, builders can create a miniature liquid cooling system that helps:

✓ Maintain more stable operating temperatures

✓ Improve long-duration running performance

✓ Reduce heat soak during demonstrations

✓ Create a more realistic engine setup

Perfect for TOYAN single-cylinder and twin-cylinder engine projects.

Option 2: Build an Independent Lubrication System

Many small model engines use splash lubrication, where oil is distributed internally by rotating components.

This micro pump allows experienced builders to experiment with external lubrication systems by circulating oil from a separate reservoir.

Potential applications include:

✓ Independent lubrication projects

✓ External oil circulation systems

✓ Custom V8 engine modifications

✓ Advanced engine engineering demonstrations

Ideal for experienced hobbyists seeking to explore pressure-fed lubrication concepts.

CNC Metal Construction

The pump body is made entirely from metal and features a compact gear-driven design.

Included in the kit:

• Metal gear pump

• Pulley

• Drive belt

• Silicone hose

• Mounting screws

• Installation bracket

Its small footprint makes integration into custom engine builds easy while maintaining a realistic mechanical appearance.

Suitable For

• TOYAN V8 engines

• TOYAN single-cylinder engines

• TOYAN twin-cylinder engines

• Methanol engines

• Nitro engines

• Custom model engine projects

• STEM engineering demonstrations

• Experimental lubrication systems

Important Notice

This product is intended for advanced DIY users.

Installation requires modification, mechanical knowledge, and system design experience. Water-cooling cylinders, radiators, oil reservoirs, fittings, and other supporting components are not included.

This pump kit is sold as a DIY modification component rather than a complete plug-and-play solution.
