High Efficiency Circulation Pump
Products
The RVP-HE-MD High Efficiency Circulation Pumps are designed for reliable and energy-efficient water circulation in heating and hot water systems. Featuring a self-adapting auto mode with PWM control, the pump automatically adjusts its performance according to system demand for optimal efficiency. It operates with low noise (≤42 dB) and minimal power consumption while offering built-in protection against over-voltage and over-current. Suitable for domestic heating, air-conditioning systems, heat pump installations, industrial hot water circulation, and solar thermal systems.
