A Steel Horizontal Elevated Make-up boiler feed unit for pumping water temperatures up 212°F (with Model P low NPSH pump). A standard, 3/16" thick, black steel receiver is ASME code constructed with dished heads; tank can be ASME code stamped if needed. An option for heavier thickness is available. Receiver also can be 300 series stainless steel for maximum corrosion resistance; most receiver sizes can be epoxy-lined or plasite-lined. Standard receiver sizes range from 77 gallons and up; customized receivers can be made for unique applications. Unit can handle a wide range of flows and pressures.
An electrical solenoid make-up water valve with float switch control is standard. Units typically available in either simplex or duplex configurations; other configurations such as triplex or quadraplex available if needed. Pump motors can be either 1750 RPM or 3500 RPM, single or three phase. Unit equipped with bronze-fitted Model D or Model P pumps fitted with industry standard motors and with mechanical seals rated for temperatures up to 250°F. Higher temperature seals and special faces available upon request. Pumps can be mounted in either a vertical or horizontal orientation. Unit can also be equipped with bronze-fitted, multi-stage pumps for high-pressure applications; tungsten carbide mechanical seals on multi-stage pumps rated up to 300°F.
Other accessories include gauge glass assembly, thermometer, inlet strainer, butterfly isolation valve, low-water cut-off or alarm switch, submerged heater tube for preheating feed water, electrical control panels and tank insulation.
