Circulation Pump Group Comap MeiFlow Combi MK/MK with Wilo Yonos Para RS 15/6 pump (MPN M26101.2)

Comap MeiFlow Combi MK/MK with Wilo Yonos Para RS 15/6 is a factory-assembled circulation pump group designed for central heating and hot water recirculation systems. The compact unit integrates a high-efficiency circulator, ball valves, union connectors and necessary fittings to simplify installation and commissioning in residential and light commercial heating circuits. The assembly supports adjustment of pump performance and is intended to ensure stable flow and temperature control within heating loops.

Advantages

The assembled pump group reduces installation time by combining the circulator and connection fittings into a single pre-tested unit. Integration of the Wilo Yonos Para RS 15/6 provides variable speed control for improved hydraulic balancing and energy-efficient operation. Built components allow straightforward connection to existing manifolds and pipework, while factory assembly helps reduce risk of leaks and incorrect component matching.

Suitable for

• Domestic central heating systems where reliable circulation is required
• Hot water recirculation loops in residential or small commercial buildings
• Retrofit projects replacing separate pump and fittings with a single assembled unit
• Applications requiring adjustable pump speed and basic hydraulic balancing

When it may not be suitable

The unit is intended for residential and light commercial applications; it may not be appropriate for larger commercial or industrial systems where higher flow rates, larger pump sizes or custom hydraulic control are required. Systems that need specialized materials, exotic seals or certifications beyond standard heating-system components should be assessed against project specifications before selection.

Key specifications

• Pump type: electronic circulator with variable speed control
• Designed application: central heating and hot water recirculation
• Mounting: compact pre-assembled group with integrated fittings
• Connection options: union connectors and ball valves for inline installation
• Material characteristics: corrosion-resistant wetted components suitable for heating fluids
• Control features: adjustable pump performance and automatic adaptation modes

How to use

Install the Comap MeiFlow Combi MK/MK group into the heating circuit following local plumbing and electrical regulations. Connect the inlet and outlet to the system piping using the integrated union connectors and secure ball valves in the required positions. Fill and purge the system to remove air, then power the circulator and set the desired operating mode and speed according to hydraulic requirements. Monitor system pressure and temperature during initial operation and adjust pump settings to achieve balanced flow and stable temperatures in the heating zones.

What to consider before purchase

• Verify compatibility with system flow rate and head requirements
• Confirm pipe diameters and connection types match existing installation
• Ensure electrical supply and wiring meet the pump's requirements and local codes
• Assess whether the pump's control features satisfy zoning and balancing needs

Usage recommendations

For reliable operation, perform routine checks on connections, valves and pump performance. Bleed air from the system after installation and seasonally as needed. Use the variable speed modes to minimize energy consumption while maintaining required flow; consult hydraulic balancing procedures when integrating multiple zones or thermostatic radiator valves.
