Wilo Star-Z NOVA circulating pump

The Wilo Star-Z NOVA circulating pump (reference: 4132760) is an ideal solution for potable water recirculation systems in single-family homes. Specifically designed to ensure a constant flow of domestic 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 comfort in the home.

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 operation under challenging potable water conditions.

The synchronous motor is lock-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 homes looking to reduce their energy bills without sacrificing performance.

The pump is equipped with a thermal insulation shell that comes standard, helping to reduce heat loss during operation, improving the energy efficiency of the system, and ensuring that the water stays hot longer in the recirculation circuit. Additionally, the pump's maximum working 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 height of up to 1 meter.

The fluid temperature range is between 2°C and 95°C, making it suitable for a wide range of domestic hot water applications. The pump is also compatible with ACS recirculation systems that have 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 thread length of 84 mm and the 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 significant modifications.

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