Mepco (formerly known as Dunham-Bush) is a major producer of steam condensate (Sentinel) pumps. They also offer centrifugal end-suction pumps, boiler feed pumps (Guardian), and vacuum pumping systems to make your steam heating system more efficient. Mepco's complete line of centrifugal pumps is designed to handle a wide range of applications. They can be used where water or other general purpose liquids are to be circulated and are available in three styles: closed coupled, base mounted, and in-line.
Mepco (formerly known as Dunham-Bush) manufacturers Guardian boiler feed pumps—a standard capacity combination receiver tank and pump unit. Guardian boiler feed pumps feature copper bearing steel tanks holding from 44 to 100 gallons of condensate. They are also available in simplex (one pump) or duplex (two pumps) units. Mepco boiler feed pump and tank combinations are normally controlled by the water level control unit on the boiler. When the boiler needs more water it sends a signal to the boiler feed pump.
Mepco (formerly known as Dunham-Bush) offers a complete line of centrifugal end-suction pumps designed to handle a wide range of applications. They can be used where water or other general purpose liquids are to be circulated and are available in three styles: closed coupled, base mounted, and in-line. Mepco centrifugal pumps can reach a maximum head of up to 150 feet and up to 2,000 GPM.
Mepco (formerly known as Dunham-Bush) offers steam high capacity condensate pumps for use when large amounts of steam heating condensate needs to be discharged. Condensate pumps are available in simplex styles with one pump and motor assembly attached to the receiver tank, as well as, duplex style pumps. Pumping capacities for these condensate pumps ranges from 2 GPM to 150 GPM. They have discharge pressures from 10 psi through 50 psi at 1750 RPM, and 10 psi through 70 psi at 3450 RPM. Standard steel tanks are available in 10, 16, 24, 33, and 44 gallon sizes, with 70 and 100 gallon optional sizes available. Cast iron tanks are available in 15, 21, 35, 50, 75, and 110 gallon sizes.
Mepco (formerly known as Dunham-Bush) steam vacuum pumps are a combination tank and pump unit. They are available in simplex (one pump for air removal, one for condensate) or duplex (two pumps for air removal, two pumps for condensate). Steam vacuum pumps eliminate air from the system, allowing for free-flow of steam, while discharging condensate back to the boiler feed tank or directly back to the boiler. The diameter of the return piping is smaller than the piping sizes found in standard gravity-like steam condensate return systems.
State Supply offers a large inventory of Mepco pump repair parts, many available via same-day shipping. Some of the repair parts available are pump and motor assemblies, water seal kits, pump impellers, replacement motors, gaskets, and many other pump repair parts for almost every Mepco pump. Repair parts are also displayed for specific pumps on the "Repair Parts" tab of any complete Mepco pump product page.
