Baxi Quantum Eco 65 H Circulator Pump

The Baxi Quantum Eco 65 H circulator pump is a high-performance solution for heating and cooling installations that require a high flow rate and efficient regulation. Designed to meet the most demanding energy efficiency standards, this wet rotor pump incorporates an ECM (Electronic Commutated Motor) technology motor with integrated electronic differential pressure regulation, allowing for optimized and quiet operation, adapted to the real conditions of the installation.

This version, identified with the reference 7504418, is capable of reaching a maximum flow rate of 40 m³/h and a maximum head of 12 m.w.c., making it ideal for medium and large-scale installations. It operates within a working temperature range of -10 °C to 110 °C and supports a maximum working pressure of 10 bar, allowing its use in both heating and cooling systems.

It complies with the ErP 2015 Directive, featuring an Energy Efficiency Index (EEI) ≤ 0.23. This value ensures a significant reduction in energy consumption compared to conventional pumps. Additionally, its intelligent operation helps eliminate flow noise in systems with thermostatic valves, as it automatically adjusts to the installation's demand.

The integrated electronic regulation allows choosing between two automatic operating modes for optimal adaptation: ΔpC (constant differential pressure) and ΔpV (variable differential pressure). This adjustment capability translates into greater thermal comfort, reduced system wear, and energy savings.

Technically, the pump operates with a single-phase power supply of 230 V and works within a speed range of 800 to 2,800 r.p.m.. The nominal current varies between 0.30 and 3.50 A, and its absorbed power ranges from 40 to 800 W, confirming its high operational efficiency even at partial load.

Regarding its construction, the Baxi Quantum Eco 65 H model features a DN 65 flange connection and a nominal diameter of 2½”. Its installation is facilitated with the complete supply of included hydraulic accessories: gaskets, flanges, counter-flanges, and screws. The electrical protection grade is IP X4D, suitable for demanding working conditions. Its total weight is 25.8 kg and its dimensions ensure easy integration into technical rooms or hydraulic panels.
