Premium smart-pump Wilo-Stratos MAXO
High-efficiency in-line glandless pump with EC motor and electronic power adjustment. Can be used for chilled water, heating water and water/glycol mixtures. Energy efficiency index (EEI) between ≤ 0.17 and ≤ 0.19 depending on pump type.
Control modes:
– Permanent, automatic performance adjustment according to system requirements without setpoint specification Wilo Dynamic Adapt plus (factory setting). Up to 20% energy savings compared to dp-v control mode.
– Constant temperature (T-const.)
– Constant differential temperature (dT-const.)
– Needs-based volume flow optimisation of the feeder pump through connectivity and communication between multiple pumps (Multi-Flow Adaptation).
– Constant volume flow (Q-const.)
– Differential pressure control (dp-c) to a remote point in the pipe network (index circuit evaluator)
– Constant differential pressure (dp-c)
– Variable differential pressure (dp-v) with the option to set the nominal duty point
– Constant speed (n-const.)
– User-defined PID control
Functions:
– Heat quantity measurement
– Cooling quantity measurement
– Pump automatically deactivates when no flow is detected (No-Flow Stop)
– Switchover between heating and cooling mode (automatic, external or manual)
– Adjustable volume flow limiter using the Q-Limit function (Qmin. and Qmax.)
– Dual-pump operations: Efficiency-optimised parallel operation for dp-c and dp-v, main and standby operation
– Ability to save and restore configured pump settings (3 restoration points)
– Fault and warning messages shown in plain text with advice on resolving the issue
– Pump venting function for automatic venting of the rotor chamber
– Automatic night setback
– Automatic deblocking function and integrated full motor protection
– Dry-running detection

– Integrated temperature sensor
– Automatic emergency operation with definable pump speed for exceptional circumstances, e.g. bus communication or sensor value malfunction
– Graphic colour display (4.3 inches) with one-button manual operation
– Use the Wilo-Assistant app to read and set operating data and –among other things– set up a commissioning protocol through the Bluetooth interface (no further accessories required)
– Integrated dual-pump management (twin-head pumps are prewired) when using 2 single pumps as two-pump unit (connection via Wilo Net)
