Wilo-TOP-Z 25/10 DM PN6/10 circulation pump 2175509

Circulation pump for domestic hot water and heating

The Wilo-TOP-Z 25/10 DM PN6/10 circulation pump is a reliable device designed for water circulation in domestic hot water (DHW) and heating systems. It finds application in both residential and commercial buildings, providing efficient medium circulation and user comfort. The pump design allows it to be used in installations powered by 230V or 400V, increasing its versatility.

Construction and application

The Wilo-TOP-Z 25/10 pump is characterized by a wet-rotor design, which minimizes the risk of damage caused by sediment and impurities in the water. The pump housing made of bronze (Rg 5) and the impeller made of polypropylene (PP-GF) ensure corrosion resistance and long life. The pump is intended for circulating water in DHW systems, as well as in heating installations where a constant medium circulation is required to maintain optimal temperature. The ability to choose from three speed settings allows for precise adjustment of the pump performance to the current needs of the installation, which translates into energy savings.

Key features and benefits

• High efficiency: The maximum pump capacity is 9.5 m³/h, and the maximum head is 9.282 m, which guarantees efficient water circulation even in extensive installations.
• Durable construction: The bronze body and polypropylene impeller provide corrosion resistance and long device life.
• Versatility: The pump is designed to operate with water temperatures from 0°C to 80°C (short-term up to 110°C), allowing its use in various types of installations.
• Performance control: Three speed stages allow for precise adjustment of the pump performance to current needs, reducing energy consumption.
• Safety: IPX4D protection class provides protection against splashing water, and insulation class H guarantees safe use.
• Easy installation: Threaded connections ISO 228-1 with a diameter of 1 ½ inch facilitate pump installation in existing installations.
• Protections: Built-in motor protections protect it against overheating and overload, increasing its reliability.
• Low energy consumption: The motor power consumption is only 0.31 kW with a rated current of 0.77 A, which translates into low operating costs.

The Wilo-TOP-Z 25/10 DM PN6/10 pump is a solid and efficient solution for any system requiring reliable water circulation – both for professionals involved in hydraulic installations and for users looking for comfort and savings in their home or company.
