FAQs

1. How to choose the right circulation pump?
Consider:
Flow rate requirements (GPM/LPM)
System pressure (head)
Liquid temperature
Material compatibility (bronze, stainless steel, etc.)
2. Where are circulation pumps used?
HVAC Systems: Heating/cooling water circulation
Domestic Hot Water: Recirculation systems
Industrial Processes: Cooling towers, boiler systems
Solar Thermal: Fluid circulation in solar panels
Aquariums/Pools: Water filtration systems
Energy efficiency (look for ECM motors)
3.What are the main types of circulation pumps?
• Inline circulators - Compact design for HVAC systems
• Wet rotor pumps - Quiet operation, common in hydronic heating
• Magnetic drive pumps - Sealless design for chemical applications
• Variable speed circulators - Energy-saving smart pumps
