Wilo-Star-Z NOVA A circulation pump 4132761

Circulation pump for efficient hot water circulation

The Wilo-Star-Z NOVA A circulation pump is a modern solution for ensuring quick access to hot water at every draw-off point. Designed for installation in residential and industrial buildings, it is characterized by low energy consumption and quiet operation. Seal-less design with a threaded connection and a motor resistant to blocked current guarantee reliability and long-term operation. The set includes a check valve and an isolation ball valve, which facilitates installation and servicing.

Product features and application

The Wilo-Star-Z NOVA A pump is designed to force the circulation of domestic hot water, especially in systems with increased water hardness – up to 20°dH. This ensures a constant water temperature in taps, eliminating the need to wait a long time for it to heat up. Low power consumption (from 3 to 5 W) translates into significant energy savings, and the compact dimensions make it easy to install in tight spaces. The pump is ideal for both new installations and the modernization of existing systems.

• Energy saving: Low power consumption (3-5W) thanks to the synchronous motor minimizes operating costs.
• Hard water resistance: Adapted to work in water with a hardness of up to 20°dH, which extends the life of the device.
• Quick installation: The Wilo-Konektor plug enables quick and easy electrical connection without the use of tools.
• High hygiene: Materials used in production meet KTW standards, ensuring safety for health.
• Valves included: Factory-mounted check valve and isolation ball valve facilitate installation and servicing.
• Durable construction: The pump body is made of brass and the impeller of plastic, providing resistance to corrosion and mechanical damage.
• Quiet operation: The use of advanced technologies reduces the noise level during pump operation.
