LEITENBERGER Mess- und Regeltechnik GmbH presents the HAP 21_SOL type, double-acting hand filling pump, which was developed specifically for solar systems. This robust device made of aluminum is essential for filling the heat transfer medium in heating systems and for precisely setting the system pressure. „Made in Germany” quality guarantees reliability and long service life, even under high back pressure.
This filling pump allows for the direct transfer of the heat transfer medium from the original storage container to the solar system's heating circuit in a simple and efficient manner.
The design of the HAP 21_SOL filling pump ensures optimal user experience and high performance:
Double Action: The pump delivers fluid with both upward and downward strokes, maximizing filling speed and efficiency.
Aluminum Construction: The light yet extremely durable aluminum body ensures long-term reliability and corrosion resistance.
High Pressure Capacity: Capable of reaching pressures up to 30 bar, making it ideal for filling and pressure testing modern high-pressure heating and solar systems.
Simple Operation: The pump is easy to handle, even under high back pressure, which significantly eases the work of technicians on site.
Versatile Connection: The connections feature threads and a hose, allowing for direct connection to the solar system.
Adjustable Height: Thanks to the different shaped plugs, the pump height can be flexibly adjusted for various reservoir sizes and connection points.
