Wilo-Stratos MAXO 65/0.5-6 PN6/10 circulation pump 2164592

Wilo-Stratos MAXO circulation pump – an intelligent solution for efficient heating and cooling

The Wilo-Stratos MAXO 65/0,5-6 PN6/10 circulation pump is an advanced device designed for circulating water in various installations – from domestic heating systems to industrial cooling circuits. A key feature of the pump is its energy efficiency, achieved through the use of an EC motor and intelligent control functions. This translates to lower operating costs and a more environmentally friendly operation of the entire system. The wet-rotor design minimizes the risk of the pump becoming blocked by impurities, which increases its reliability and extends its service life.

The pump offers a wide range of configuration and control options, tailored to the specific needs of each installation. The built-in motor speed controller allows for precise adjustment of the pump's performance to current demand, which further optimizes energy consumption. The ability to communicate via RS-485 and Bluetooth interfaces enables integration with BMS (Building Management System) and remote control and monitoring of the pump's operation.

Construction and design features

The pump body is made of durable cast iron GG 25 (GJL-250), which ensures corrosion resistance and long-term reliability. The impeller made of PPS-GF40 guarantees high resistance to abrasion and aggressive media. The shaft made of 1.4028 steel with DLC coating ensures smooth and quiet pump operation. The connection length is 280 mm, and the diameter of the flanged connection is DN 65 on both the inlet and outlet sides. The maximum working pressure is 10 bar, and the maximum head is 6.728 m.

It is worth noting the energy efficiency index (EEI) of 0.17, which places this pump at the forefront of energy-efficient devices available on the market. Insulation class F ensures safe operation over a wide range of ambient temperatures (-10 to 40 °C). Protection class IPX4D protects the pump against splashing water. The digital and analog connection in standard facilitates integration with existing control systems.
