Meibes manifold for 5 circuits with pump groups, 1" connections, model 66301.3

Meibes manifold for 5 circuits with pump groups, 1" connections, model 66301.3 is a hydraulic distribution unit designed to manage flow to five separate heating or cooling circuits. The unit provides centralized supply and return connections with 1" ports and is prepared for integration with pump groups, enabling streamlined hydraulic connection between a heat source and multiple zones. It is suitable for use in compact boiler installations, multi-zone underfloor heating layouts and other systems that require organized circuit distribution and pump attachment.

Advantages

The manifold combines five circuit distribution with dedicated pump-group compatibility to simplify installation and reduce pipework complexity. Its 1" supply and return connections provide a standardized interface for connecting to boilers, heat pumps or buffer tanks. The compact arrangement of ports and the factory-matched geometry help ensure consistent flow distribution, easier balancing and more orderly system layout. Designed for practical hydraulic integration, it supports efficient zone control without requiring extensive customization.

Suitable for

• Multi-zone underfloor heating systems with five circuits
• Small to medium radiator or panel heating installations with centralized circulation
• Retrofitting or new-build compact boiler rooms where pump groups are used
• Hydronic cooling circuits with separate zone control

Key specifications

• Number of circuits: 5
• Connection size (supply and return): 1"
• Prepared for integration with pump groups
• Function: hydraulic distribution for heating and cooling circuits
• Suitable for centralized flow distribution and circuit balancing

How to use

Install the manifold on a solid mounting surface or within a mounting cabinet at the hydraulic center of the plant. Connect the 1" supply and return ports to the main circulation loop, then connect each circuit outlet to its respective heating or cooling loop. Fit compatible pump groups onto the manifold according to the pump group manufacturer's instructions and ensure all joints and connections are sealed and torque-tightened to recommended values. Commission the system by purging air from each circuit, setting flow rates or balancing valves as required, and verifying proper operation of the pump groups and control devices.

Usage recommendations

Use the manifold as part of a coordinated hydraulic design: match pump group capacity to system head and flow requirements, fit appropriate balancing valves or flow meters on each circuit, and follow local standards for piping, mounting and insulation. Regularly inspect connections and seals for leaks and ensure periodic maintenance of pump groups and control components to maintain reliable operation.
