Wilo-Stratos MAXO 50/0.5-12 PN6/10 circulating pump

Smart Premium Pump Wilo-Stratos MAXO

Introducing the Wilo-Stratos MAXO glandless inline pump - a dedicated solution for installations where the highest efficiency and energy savings are important. Equipped with an EC motor with electronic capacity adjustment, the pump is ideally suited for hot water, cold water and a mixture of water and glycol. Depending on the version, the energy efficiency index (EEI) is ≤ 0.17

Types of control

• Constant, automatic adaptation of power to system requirements without inputting setpoints - Wilo-Dynamic Adapt plus (factory setting). Energy savings of up to 20% compared to dp-v control mode.
• Fixed temperature (T-const.)
• Constant differential temperature (dT-const.)
• Demand-adapted rotary flow optimization (Multi-Flow Adaptation) - connection and communication with several pumps
• Constant flow (Q-const.)
• Control of differential pressure dp-c at a remote point in the pipeline (erroneous point control)
• Constant differential pressure (dp-c)
• Variable differential pressure (dp-v) with nominal operating point input capability
• Constant speed (n-const.)
• User-defined PID control

Functions

• Heat and cold quantity recording
• Automatic shutdown when zero flow is detected (No-Flow Stop)
• Switching between heating and cooling modes - automatically, externally or manually
• Adjustable flow limitation by Q-Limit function (Qmin. and Qmax.)
• Dual pump mode: efficiency-optimized operation with connection for dp-c and dp-v, basic or reserve mode
• Saving and restoration of configured settings (3 restore points)
• Failure and warning signaling in text form with diagnostic assistance
• Rotor chamber venting function
• Automatic night lowering mode
• Automatic non-locking function and full motor protection
• Dry operation detection

• Wilo CIF module slot with interfaces for building automation (optional accessories: CIF modules Modbus RTU, Modbus TCP, BACnet MS/TP, BACnet IP, LON, PLR, CANopen)
• Wilo Net system - communication bus that allows Wilo products to work together (e.g. Multi-Flow Adaptation, double pumps, Wilo-Smart Gateway)
• Integrated temperature sensors
• Automatic fail-safe mode - maintains defined speed in emergency situations such as loss of communication or incorrect sensor values
• Graphic color display (4.3 inches) operated by one-button manual operation module
• Bluetooth interface for reading and setting of operating data and protocol generation (Wilo-Assistant app)
• Integrated dual pump operation management (wiring of two single pumps as a dual pump unit using Wilo Net)
• Possibility to detect wire breaks in the analog signal (for 2-10 V or 4-20 mA)
• Outdoor mounting with protection against climatic factors (according to instructions)
• Date and time set as standard
• Thermal insulation covers for heating installations
