Wilo-Stratos MAXO 40/0,5-4 PN6/10 circulation pump 2164582

Intelligent circulation pump for demanding installations

Wilo-Stratos MAXO 40/0,5-4 PN6/10 is an advanced, wet-rotor circulation pump with an EC motor, designed for a wide range of applications in heating, air conditioning and industrial systems. Its design and functionality ensure high energy efficiency and precise control over medium flow. The pump is distinguished by its intuitive operation, rich communication possibilities and a 5-year manufacturer's warranty.

Design and application in practice

The pump is designed for reliable operation in various installations. Made of high-quality cast iron GG 25 (GJL-250) ensures durability and corrosion resistance. The impeller made of PPS-GF40 guarantees mechanical and chemical resistance. The EC motor with a built-in frequency converter enables smooth speed control, adapting the pump's performance to current demand. This minimizes energy losses and operating costs.

The Wilo-Stratos MAXO pump is perfect for:

• Water heating installations (radiators, underfloor heating, ducted air heating).
• Air conditioning installations (plate coolers, air conditioning units).
• Closed cooling circuits.
• Industrial circulation installations.
• Systems with heat exchangers and buffer tanks.

Functionality and benefits for the user

The pump offers a number of intelligent functions that optimize its operation and facilitate integration with building automation systems:

• Dynamic Adapt plus: Automatically adjusts the pump's performance to changing hydraulic conditions in the system, ensuring optimal comfort and energy savings.
• Multi-Flow Adaptation: Enables the pump to operate in systems with variable flow characteristics, ensuring stable operating parameters.
• Control modes: A wide selection of control modes (constant differential pressure, variable differential pressure, constant flow, constant temperature) allows you to adapt the pump to the specifics of the installation.
• Bluetooth interface: Enables wireless configuration and monitoring of the pump using a mobile application.
• Communication: Support for RS-485 protocols and the ability to expand with CIF modules (Modbus TCP/RTU, BACnet IP/MS/TP, LON, CANopen, PLR) enables integration with BMS systems.
• Built-in potential-free switching contact: Allows remote control of the pump or signaling of an emergency condition.
• Energy Efficiency Index (EEI): A very low EEI of 0.2 confirms the high energy efficiency of the pump.

Additionally, the pump has electronic protections that protect the motor from overload and detect a lack of medium flow – which translates into a longer service life of the device and minimizes the risk of failure. The maximum head is 4.516 m with a maximum flow rate of 16 m³/h and the motor power consumption is 0.13 kW with a rated current of 0.93 A. The IPX4D protection class provides resistance to splashing water, which is important during installation and operation of the device.
