Condensate Pumps

Condensate Pumps are electrically powered centrifugal pumps used in hydronic systems. When used in heat exchangers, they are often fairly small in horsepower. These pumps have a tank in which condensate accumulates and they usually run intermittently. The accumulated liquid raises a float switch, which in turn, energizes the pump. The pump runs until the liquid level in the tank is lowered. Some condensate pumps contain 2 stage switches. This allows the liquid to rise to a trigger point in the 1st stage until the pump is activated. As the liquid continues to rise, the 2nd stage will be triggered. If the 2nd stage is triggered, this could possibly mean the discharge is blocked or the pump has failed. Condensate can contain many contaminates, chemicals and can be acidic. Always have an experienced HVAC contractor take a look at it before you risk skin burns.
