FAQs

1.What is a circulation pump?

A circulation pump is designed to continuously move liquid through a closed-loop system, maintaining constant flow and pressure. Unlike transfer pumps, it operates against system resistance rather than creating new pressure.

2. How does a circulation pump work?

Uses an impeller to create continuous fluid motion

Operates against existing system pressure

Typically runs at constant speed (or variable speed in advanced models)

Maintains consistent flow without needing to re-prime

3. What's the difference between a circulation pump and a booster pump?

Feature	Circulation Pump	Booster Pump
Purpose	Maintain flow in closed loop	Increase pressure in system
Operation	Continuous	On-demand
Pressure	Works with existing pressure	Creates additional pressure
Typical Use	Heating systems	Water supply systems
