Pump 25-40-130 0203W

Circulation pump for heating systems and potable water installations

The 25-40-130 pump is a reliable device designed for circulating water in central heating systems and potable water installations. The construction based on a durable cast iron body and an aluminum housing guarantees long-lasting and trouble-free operation. The impeller made of plastic, combined with sliding bearings and a ceramic shaft, ensures quiet operation and corrosion resistance.

The pump features adjustable performance thanks to three speed settings, which can be adapted to the specifics of the installation. The two-pole asynchronous motor does not require additional overload protection, simplifying installation and operation. The device meets the stringent European standards EN 60335-1 and EN 60335-2-51, confirming its safety and high quality.

Key features and benefits:

• Durable construction: The cast iron body provides corrosion resistance and long pump life.
• Versatility: Can be used in central heating systems and potable water installations.
• Performance adjustment: Three speed settings allow for optimal adaptation to installation needs.
• Safety: Complies with European standards EN 60335-1 and EN 60335-2-51.
• Reliability: High-quality asynchronous motor does not require additional overload protection.
• Quiet operation: The combination of a plastic impeller, sliding bearings and a ceramic shaft minimizes noise levels during pump operation.

Application:

The 25-40-130 pump is ideal for:

• Central heating systems (CH) – circulating heating water.
• Domestic hot water installations (DHW) – ensuring continuous circulation of potable hot water.
• Solar systems – supporting the flow of fluid in solar collectors.
• Residential buildings, public utility facilities and in industry.

The pump is characterized by a flow rate in the range of 0.2 to 3.5 m³/h, a maximum head of 3.8 m and a maximum working pressure of 10 bar. The liquid temperature can range from +2 to +110°C, and the pump protection class is IP 44. The supply voltage is ~230V / 50-60Hz, and the power consumption is 35/45/65 W. The connection spacing is 130 mm, and the connection has a G 1 1/2" thread.

Remember to use a mesh filter with a density of at least 200 meshes/cm² to protect the pump from damage caused by impurities in the water. The pump should be installed in accordance with the operating instructions, maintaining a horizontal shaft arrangement and proper positioning of the terminal box (not under the pump).
