Wilo Star-Z NOVA T circulating pump

The Wilo-Star Z NOVA T circulating pump (reference: 4222650) is an efficient and highly reliable solution, specifically designed for domestic hot water systems in single-family homes. This wet rotor circulating pump is particularly suitable for potable water applications, providing a constant and efficient flow of hot water, and helping to maintain an optimal temperature in the domestic hot water recirculation system.

Manufactured with a high-quality brass housing, the Wilo-Star Z NOVA T is designed to resist corrosion and offer a long service life in potable water environments. Additionally, the Noryl impeller and ceramic shaft ensure reliable and quiet operation. The material of the bearing is resin-impregnated carbon, which adds durability and smoothness to the daily operation of the pump.

One of the main benefits of this pump is its block-resistant synchronous motor, which features a high starting torque, meaning that the pump can start and operate optimally even under difficult conditions or when higher initial power is required. This ensures that the pump operates smoothly over time, reducing the risk of interruptions or breakdowns.

The Wilo-Star Z NOVA T is extremely energy efficient, with a power consumption of only 6 W, making it a very economical option for domestic hot water systems. Its energy efficiency is combined with a range of advanced features that make it easy to use and maintain. For example, it comes equipped with an integrated switch timer and temperature control, allowing for precise and automatic adjustment of the pump's operation, optimizing energy consumption based on the actual demand for hot water.

A standout feature of this pump is its anti-legionella thermal recognition routine. This system is designed to ensure that the water temperature is maintained within a safe range, helping to prevent the proliferation of bacteria such as legionella, a risk in poorly managed hot water systems. The pump works in conjunction with the heating system to ensure that the water is kept at temperatures that prevent the development of these bacteria, providing a safer environment for water consumption.

Additionally, the pump includes a thermal insulation shell as standard, which helps to reduce heat loss and maximize the efficiency of the domestic hot water system. It is also equipped with a non-return valve and a ball valve with G1 thread, which facilitates maintenance and ensures that the system operates efficiently and without setbacks.

In terms of operational capacity, the Wilo-Star Z NOVA T supports a maximum working pressure of 10 bar and a fluid temperature range of 2°C to 95°C, making it suitable for a wide range of domestic hot water applications. Its compact design, with a thread length of 138 mm and G1 pipe connections, allows for easy installation and adaptability to different systems.
