Rothenberger - ROSOLAR Pump Solar System Filling Pump - 1500000135

Rothenberger ROSOLAR Pump: Efficiency and Reliability for Solar Systems

The Rothenberger ROSOLAR Pump 1500000135 is a professional solution for filling, flushing, and venting solar thermal systems. Specifically designed for solar system installers and maintenance technicians, this pump combines robustness, practicality, and high performance in a single tool.

Technical Features

The ROSOLAR Pump is equipped with a powerful motor that ensures optimal flow for quick and efficient operations. With a 30-liter tank capacity, it allows work on medium and large systems without frequent interruptions for refilling. The pump generates a maximum pressure of 5 bar, ideal for overcoming the typical resistances of solar circuits, even the most complex ones or those installed in multi-story buildings.

Versatility and Applications

This professional tool has been developed for multiple operations:

• Initial filling of solar thermal systems with heat transfer fluid
• Flushing circuits to remove processing residues
• Effective venting to remove air and gas from the system
• Periodic maintenance with heat transfer fluid replacement
• Restoring optimal pressure in systems

Functional and Practical Design

The ROSOLAR Pump features a compact and robust design, with materials resistant to the chemicals present in heat transfer fluids. The integrated trolley with large-diameter wheels facilitates transport even on uneven surfaces such as roofs or terraces. The controls are ergonomically and intuitively positioned, allowing precise adjustment of pressure and flow during operations.

Benefits for Professionals

Using the ROSOLAR pump offers numerous benefits to installers:

• Significant reduction in system commissioning times
• Effective elimination of air from the circuit, preventing circulation problems
• Ability to thoroughly flush the system before final filling
• Precise pressure control during all operational phases
• Compatibility with all standard heat transfer fluids for solar systems

Safety and Reliability

The pump is equipped with protection systems that prevent motor overheating during prolonged use. Gaskets and components in contact with fluids are made of specific materials to resist high temperatures and the chemical characteristics of solar liquids. The integrated filter protects the pump from any impurities present in the circuit during flushing operations.

Accessories and Connections

The ROSOLAR Pump comes with a complete set of fittings and adapters that ensure compatibility with most solar systems on the market. The high-resistance flexible hoses included in the package allow convenient access to filling points even in difficult positions. The integrated manometer allows constant pressure monitoring during all work phases.

Maintenance and Durability

Designed for intensive professional use, this pump requires minimal maintenance. Wear components are easily accessible and replaceable, ensuring a long operational life for the tool. The robust structure effectively protects mechanical and electrical parts even in arduous working conditions typical of construction sites.
