Wilo Star-Z NOVA Circulating Pump

The Wilo Star-Z NOVA circulating pump (reference: 4132760) is the ideal solution for drinking water recirculation systems in single-family homes. Specifically designed to ensure a constant flow of hot water, this wet rotor pump offers reliable and efficient performance, ensuring that hot water is instantly available at consumption points, preventing water waste and enhancing home comfort.

Manufactured with a corrosion-resistant brass housing (CW617N), the Wilo Star-Z NOVA guarantees long-term durability. Its Noryl impeller and ceramic shaft ensure quiet and efficient operation, while the resin-impregnated carbon bearings provide smooth, maintenance-free performance. These high-quality materials make the pump resistant to wear and suitable for operating under challenging potable water conditions.

The synchronous motor is blockage-resistant, ensuring that the pump continues to operate smoothly even after long periods of inactivity. The motor also features a high starting torque, meaning the pump can start effectively even under load conditions. With a power consumption of only 3 to 5 W, this pump is extremely energy-efficient, making it an ideal choice for households looking to reduce their energy bills without sacrificing performance.

The pump comes equipped with a thermal insulation shell as standard, which helps reduce heat loss during operation, improving the energy efficiency of the system and ensuring that water remains hot for longer in the recirculation circuit. Additionally, the pump's maximum operating pressure is 10 bar, allowing it to operate in a variety of potable water applications, offering a maximum flow rate of 0.4 m³/h and a head of up to 1 metre.

The fluid temperature range is between 2°C and 95°C, making it suitable for a wide range of hot water applications. The pump is also compatible with domestic hot water recirculation systems with a maximum total hardness of up to 20 °dH (3.57 mmol/l), making it versatile and applicable in various water supply conditions.

In terms of installation, the 84 mm thread length and Rp ½ threaded connections on both the suction and discharge sides make installation easy and quick. This allows the pump to be efficiently integrated into the existing system without the need for additional adapters or major modifications.

The IP42 motor protection ensures the pump is protected against water splashes and the ingress of foreign objects, making it suitable for standard operating environments. Additionally, it meets the requirements for electromagnetic compatibility according to standards EN 61000-6-3 (interference emission) and EN 61000-6-2 (interference resistance), ensuring the pump operates stably even in complex electromagnetic environments.
