Features and Information

High compatibility:
Specifications: 25-40/180. This cast iron circulation pump is specifically designed for underfloor heating systems and provides a maximum flow rate of 50 l/min and a head of 4 m. With a 38 mm threaded connection, it easily replaces an existing hot water circulation pump and meets the requirements of both residential and complex piping systems.

Durable construction:
The cast iron housing and IP44 protection rating ensure reliable operation over a wide temperature range from 2 °C to 110 °C. A high-performance pure copper motor and a fully enclosed junction box guarantee stable and reliable long-term operation.

Low noise level:
Thanks to its pure copper motor and special internal design, the pump operates at a maximum noise level of just 45 dB, ensuring a quiet and undisturbed environment even near the heating zone.

Adjustable flow rate:
Three adjustable speed settings allow you to tailor the intensity of water circulation to seasonal needs or a specific application, improving energy efficiency and comfort.

Versatile accessories:
The set includes two 38 mm × 25 mm cast iron adapters and rubber O-rings, which ensure compatibility with the most common pipe diameters and facilitate both the installation of new systems and the replacement of existing equipment.

Our circulation pump provides a maximum flow rate of 50 l/min, a maximum lift height of 4 m, a 38 mm threaded connection, and a 38 × 25 mm adapter, making it an ideal replacement for your existing hot water circulation pump. Three-speed control allows you to adjust water circulation to meet seasonal needs.

This cast-iron circulation pump, equipped with a durable, all-copper motor, ensures powerful water circulation with minimal energy consumption. It guarantees long-lasting operation while keeping operating costs low without compromising efficiency.

This hot water circulation pump is equipped with two durable rubber seals that prevent leaks at the connections, protect the heating system from water damage, and help avoid unnecessary repairs or water loss.

Proper maintenance is essential. After installation or system maintenance, be sure to bleed the air through the bleed valve to ensure smooth operation and protect the system from potential damage.

Make sure that the hot water circulation pump is installed in a dry environment with a properly functioning drainage system. This prevents potential property damage caused by water leaks and ensures optimal operation.
