Bell & Gossett’s Domestic Pump Series CMED-eSV is offered for boiler feed systems up to 975 BHP. The CMED-eSV offers a flexible solution for handling feed water. The CMED-eSV has a receiver elevated 30” from the floor that is available in Steel, Galvanized Steel, or Epoxy Lined Steel with a manhole for inspection. ASME construction or Stainless Steel are available on request. The receiver is sized for 10-minute net storage. Units include receivers, pumps, pump suction isolation valves, make-up valve and overflow connection. The pumps are controlled by a dedicated pump control on the boiler (available as optional) responding to water level change in the boiler. This maintains optimum steaming level in the boiler for maximum performance and safety.
The pump is a multi-stage, centrifugal design, stainless steel construction with a carbon/silicon, carbon/viton stainless steel construction seal rated to 250 degrees. Pumps are rated up to 200 psi (462 tdh) discharge pressure and are supplied with ANSI flanges as standard. The CMED-eSV is available in simplex, duplex and triplex configurations. Additional pumps are available on request. Water make up uses a Float switch and Solenoid valve with “Y” strainer to add make-up water on low level. Tempering the added cold water with the hot condensate in the receiver minimizes the danger of thermal shock to the boiler.
