Wilo Yonos PICO 25/1-4-130 High-Efficiency Circulator Pump - 130mm, 230V, for Heating & Hot Water Systems
The Wilo Yonos PICO 25/1-4-130 High-Efficiency Circulation Pump 4215514 is a glandless, electronically controlled pump designed for hot-water heating systems, air-conditioning, and industrial circulation applications, featuring ECM technology for energy savings and reliable performance.
Product Description
The Wilo Yonos PICO 25/1-4-130 is a maintenance-free circulation pump with a wet motor, threaded connection, and integrated electronic power control. It offers preselectable control modes for constant or variable differential pressure, making it suitable for underfloor heating, radiator systems, and similar applications. The compact 130 mm port-to-port length allows for flexible installation in space-constrained areas. With a minimum power consumption of just 4 W and high starting torque, it ensures efficient and reliable operation while reducing energy costs.
Key Features
- High-efficiency ECM motor: Achieves very high degrees of efficiency with minimum power consumption of 4 W.
- Control modes: Δp-c (constant differential pressure) and Δp-v (variable differential pressure) for optimized performance.
- Integrated functions: Motor protection, LED display for setpoint and power consumption, automatic deblocking, and venting function.
- Quick connection: Wilo-Connector for easy electrical installation.
- Compact design: 130 mm port-to-port length for flexible mounting.
- Energy Efficiency Index (EEI): ≤ 0.20 for superior energy savings.
- High starting torque: Ensures reliable startup even after long downtimes.
