MX Series Condensate and Boiler Feed Pump Package

ThermaFlo "MX" Series condensate and boiler feed pumps are packaged units completely assembled, wired and tested at the factory. They are used in low pressure steam heating systems to collect and quickly return condensate to the boiler or boiler feed unit. Pumping action is controlled by an integral float switch on simplex (one pump) units or mechanical alternator on duplex (two pump) units. Unlike boiler feed units which are controlled by a boiler mounted control and equipped with a makeup valve mechanism, condensate pumps usually do not directly supply boiler makeup water.

AVAILABLE TYPES

Simplex units

Simplex units are equipped with vapor tight, heavy duty float switch control with stainless steel float. Easily field adjustable to provide proper pump control and operation.

Duplex units

Duplex units offer some additional distinct advantages over simplex units. They are used where an unusually heavy amount of condensate must be returned or where it is desirable to have a stand-by pump available. Equipped with a float operated, automatic mechanical alternator, they provide several benefits. Both pumps run on high level.

• System overload protection: The second pump is activated if the rate of condensate return exceeds the limits of the first pump.

• Extra-long service life: Each of the two pumps is activated automatically on alternating pumping cycles so the workload is evenly distributed between the two pumps.

• Back-up system protection: A second pump is automatically actuated if the first one fails to start. Maintenance or repairs can be done on either pump without shutting down the other one or interrupting system operation.
