Brochure - VMX Condensate Pumps

Condensate pumps are used in 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 make-up valve mechanism, condensate pumps usually do not supply boiler make-up water.
