Xylem-McDonnell & Miller 51-S-HD Head Mechanism 51-S 135800

The Xylem-McDonnell & Miller 51-S-HD 51-S Head Mech 135800 is a head mechanism for pump controllers from the 51-S series. It is the main part that controls the pressure and flow of water in different HVAC systems, such as cooling towers, chillers, and boilers. A float senses changes in the liquid level, and this head mech converts those changes into electrical impulses. The pump's functioning is then managed by these signals, guaranteeing appropriate system pressure and water circulation. Its single-stage, non-clog design allows it to handle a variety of liquids efficiently. Its enclosed impeller reduces wear and noise. This head mech ensures that your HVAC system runs smoothly even in the face of a variety of problems, such as leaks, noisy operation, and subpar pump performance.
