Solar Pump Station SR962S
The Demax SR962S is a preassembled, leak-tested double-pipeline solar pump station designed to transfer heat from solar collectors to storage tanks. It operates via a dual-pipeline layout (flow/return) with integrated valves (ball/check) to prevent gravity-driven circulation. Temperature sensors and a controller manage heat transfer by activating circulation pumps based on collector-tank temperature differences (ΔT). The system includes monitoring components (flow rate checker, manometer) and safety devices (safety valve), while its controller supports user/engineer-grade parameter setup to automate functions (e.g., pump speed control, frost protection) and optimize thermal efficiency.
