A High Temperature Make-up boiler feed unit designed for pumping water temperatures up 300°F. Unit used when there are no other return loads and the temperature of load is higher than the saturation temperature. Pumping at temperatures higher than saturation temperature directly to boiler eliminates vent loss and exposure to atmospheric oxygen. A standard black steel receiver with dished heads is ASME stamped for 125 psig. Unit can handle a wide range of flows and pressures. Units are elevated style and designed for capacities from 2,500 to 40,000 lbs per hour with tank sizes ranging from 66 gallons up to 190 gallons; however customized receivers can be made for applications outside the standard tank dimensions.
An electrical solenoid make-up water valve with float switch control is standard. Units are available in either simplex or duplex configurations; motors are 3500 RPM, single or three phase. Unit equipped with bronze-fitted, Model P low NPSH pump fitted with industry standard motors and with mechanical seals rated for temperatures up to 300°F.
Other accessories include gauge glass assembly, thermometer, inlet strainer, butterfly isolation valve, low-water cut-off and electrical control panels.
