# Leitenberger HAP 02_SOL Solar Collector Manual Filling Pump \u2013 Precision Fluid Transfer<\/p>\n
The Leitenberger HAP 02_SOL manual filling pump is a robust and reliable device specifically designed for the precise filling and circulation of heat transfer media used in heating systems, with a special focus on solar collector systems. Guaranteed by \u201eMade in Germany\u201d quality, this pump ensures fast and easy filling directly from the original container into the solar collector system.<\/p>\n
This high-quality manual pump, made of aluminum, is the ideal choice for servicing, maintenance, or commissioning new systems where the pressure-controlled, controlled injection of the heat transfer medium is essential.<\/p>\n
## Main Features and Advantages<\/p>\n
The HAP 02_SOL filling pump combines user-friendly design with durable, industrial-grade material usage:<\/p>\n
* **Direct Filling:** Allows the heat transfer fluid (e.g., antifreeze) to be pumped directly from the original container into the solar collector system, minimizing loss and contamination risk.
\n* **Robust Construction:** The pump body is made of durable aluminum, which resists frequent use and contact with various media.
\n* **Easy Handling:** The pump connects quickly and is extremely simple to operate, significantly speeding up the filling process.
\n* **Sufficient Pressure Rating:** Capable of reaching pressures up to 6 bar, which is enough to fill most domestic and smaller industrial solar collector systems.
\n* **Long Hose:** The included 500 mm long hose provides sufficient range of motion during operation, even in hard-to-reach areas.<\/p>\n

## Detailed Application Description<\/p>\n
The Leitenberger HAP 02_SOL filling pump is an essential tool for the maintenance of solar collector systems. Solar systems are closed heating circuits that contain a special heat transfer medium (usually antifreeze liquid). Regular checking and refilling of these media, if necessary, are indispensable for maintaining the system's efficiency and service life.<\/p>\n
**Filling Process:**<\/p>\n
1. **Connection:** Using the connector equipped with a G 3\/4\u201c BSP thread, one end of the pump must be connected to the heat transfer fluid storage container, while the other end must be connected to the filling nipple of the solar collector system.
\n2. **Pumping:** The user manually sucks the medium from the reservoir using strokes of approx. 80 mm on the pump body, and then pushes it into the system.
\n3. **Pressure Monitoring:** The pump allows for the gradual increase of system pressure, during which the air present in the system is displaced, and the desired operating pressure (usually 1-3 bar, but the pump can fill up to 6 bar) can be set. During filling, the pressure development must be continuously monitored using the pressure gauges present in the system.<\/p>\n
The compact length of 220 mm and the lightweight aluminum design facilitate the transport and storage of the pump in the service vehicle. The 500 mm hose ensures that the pump can be placed even far from the tank to be filled, thus increasing the safety and convenience of the operation.<\/p>\n
