FIGURE 37 Thermostatic control for condensate recirculation

Just as in the case of boiler-feed pumps—or, as a matter of fact, of any pumps— condensate pumps should not be operated at shutoff or even at certain reduced flows. This subject is covered in detail in Subsections 2.3.1 and 2.3.4. Emphasis is placed on the importance of preventing "dead-heading," where the weaker pump in a two-pump system with only one minimum flow protection loop is forced to operate at shut-off or zero flow rate.
