Type BVMC

Big Vacuum and Condensate unit with independent air and water pumps. Multi-jet design proven effective and reliable for removing air and lifting hot condensate in the return system. A standard cast iron receiver is provided with a standard 20-year warranty against corrosion failure for years of service or a rectangular steel tank. The vacuum tank (or hurling chamber) is either heavy gauge, black steel or cast iron depending upon sizing. Standard unit designed for applications with system capacities ranging up from 1,000 square feet EDR; air pumps range up from 5.8 cubic feet per minute (cfm) at 5-1/2" HG at 160°F. Unit completely packaged, including electrical controls.

Units are available in either simplex or duplex configuration with either 1750 RPM or 3500 RPM motors in either single or three phase. Pumps are flange mounted to the receiver and equipped with industry standard motors. Pumps bronze-fitted with removable bronze wearing ring and with mechanical seals rated for temperatures up to 250°F. Higher temperature seals and special faces available upon request.

Air and water pumps can be sized separate for customized applications that standard unit configurations can not meet.

Type BVMC is the boiler feed unit version of the BVC. An electrical solenoid make-up water valve with float switch control is standard. A low water cut-off switch is furnished to prevent pumps from operating should the make-up water assembly fail to prevent the pumps from running dry and burning up the mechanical seals. Numerous options are available.
