The Wilo Atmos Pico 25/1-6-130 is an electronically controlled, high-efficiency glandless circulator developed to optimise flow dynamics across demanding heating and air-conditioning applications. Powered by ECM technology, the blocking-current proof synchronous motor delivers variable differential pressure control to ensure precise hydraulic balancing and vastly reduced energy consumption, drawing a minimal 4W during low-load periods. The unit is constructed with a robust grey cast iron housing, a durable polypropylene impeller, and a stainless steel shaft supported by metal-impregnated carbon friction bearings to ensure maintenance-free longevity.

Equipped with a straightforward LED interface, the pump provides immediate visual feedback on normal operation or fault conditions alongside the selected control mode. Installers can easily preselect from multiple operating parameters, including variable differential pressure, constant differential pressure, and three constant speed stages, allowing for optimum load adjustment. Featuring an automatic deblocking function and high starting torque, this reliable circulator ensures uninterrupted circulation even after prolonged periods of system inactivity.

Q: What is the minimum power consumption of this circulator?
A: The highly efficient ECM motor can operate on as little as 4W during periods of low hydraulic demand.

Q: Does the pump offer variable control settings?
A: Yes, it features selectable variable and constant differential pressure modes alongside fixed constant speed stages.

Q: What materials are used in the internal construction?
A: The pump utilises a polypropylene impeller, a stainless steel shaft, and robust metal-impregnated carbon friction bearings.

Q: How does the interface indicate an operational fault?
A: The built-in LED display will flash or illuminate to clearly signal a fault condition to the user.
