Filling/Circulation Pumps for small systems with AC networks

Thermal solar power systems have become very popular in the past (several) years, thanks to a perfected technical design. These pumps are now built for low-flow solar power systems. The use of wet motors like those proven in millions of central heating systems combined with the gear pump principle ensures an optimal compromise between costs and pump parameters.

• Flow rate 2 - 3 l/min
• Max. pressure rise: 3 bar
• Max. inlet pressure: 3 bar

Compact Filling/Circulation Pumps for small systems

These pumps represent a further step in development. The optimized size, weight, noise level and efficiency facilitate extremely efficient transport of the heating fluid. The continuous RPM and flow rate control make this concept very appealing. Drive concepts with 230V, 50Hz and 12V/ 24V DC are available as options.

• Possible flow rates: 0.1 - 8 l/min
• Max. pressure rise: 5 bar

Feed/Circulation Pumps for large solar power systems Large thermal solar systems and power stations require large circulation flows.

• Possible flow rates: 1 - 90 l/min
• Max. system pressures: up to 10 bar
• Max. pressure rise: 8 bar
