Circulation pump EXEC BETA II 25-40/180 – inline central heating pump 25/40, 180 mm

EXEC BETA II 25-40/180 is a circulation pump for central heating and domestic hot-water systems. The pump has a 25 mm connection size, a nominal head class of 40 and a 180 mm distance between pipe centers, providing continuous circulation of heating medium to radiators, boilers and heat exchangers in residential and small commercial installations. Designed for inline installation, it supports stable heat distribution and simplifies system maintenance by maintaining flow through the circuit.

Advantages

The inline design and 180 mm pipe-center spacing make the pump suitable for direct replacement in common heating circuits. Its 25 mm connection size offers compatibility with standard pipework, while the 40 head class provides sufficient pressure for multi-radiator layouts in low- to medium-height systems. The pump is built for continuous operation and helps reduce temperature stratification by keeping the circulation consistent across the system.

Suitable for

• Residential central heating systems with radiators
• Domestic hot-water circulation and boiler loop boosting
• Small commercial heating installations with modest head requirements
• Replacement of existing inline pumps with 180 mm pipe-center spacing

Key specifications

• Connection diameter: 25 mm
• Nominal head class: 40 (kPa class)
• Distance between pipe centers: 180 mm
• Installation: inline (center-to-center mounting)
• Application: central heating and hot-water circulation

How to use

Install the pump inline in the heating circuit with the specified 180 mm distance between pipe centers and secure the connections to match the 25 mm pipe diameter. Follow the system manufacturer’s guidelines for orientation and flow direction, ensuring correct alignment with existing piping. After mechanical installation, vent air from the circuit, check for leaks, and power the pump according to local electrical codes. Adjust system controls and verify that the pump maintains steady circulation without abnormal vibration or noise.

Usage recommendations

For reliable operation, ensure the system is free of debris and scale that could impair hydraulic performance. Use appropriate strainers or filters upstream if the installation site has particulate risk. Verify compatibility with the system’s temperature and fluid type, and schedule periodic checks for sealing, electrical connections and bearing noise to extend service life.
