TYPE SHVM - STEEL HORIZONTAL MAKE-UP
Type SHVM is the boiler feed unit version of the SHVC where an electrical solenoid make-up water valve with float switch control is standard. A low water cut-off switch is provided to stop 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.
This Steel Horizontal Vacuum and Condensate unit comes with independent air and water pumps. The multi-jet design has proven effective and reliable for taking out air and lifting hot condensate in the return system. A standard heavy gauge black steel receiver from 3/16" to 3/8" thick provides for years of serviceability. The receiver is divided into two compartments whereby one side is used for collecting hot condensate and the other side is the vacuum chamber. The standard unit is designed for applications with system capacities ranging up from 1,000 square feet EDR; air pumps range up from 6 cubic feet per minute (cfm) at 5-1/2" HG at 160°F. This unit is completely packaged and incudes electrical controls.
The units are available in simplex or duplex design with either 1750 RPM or 3500 RPM motors in either single or three phase. The pumps are flange mounted to the receiver and equipped with industry standard motors. The pumps are bronze-fitted with a removable bronze wearing ring and with mechanical seals rated for temperatures up to 250°F. Higher temperature seals and special faces are also available upon request.
Air and water pumps can be sized separately for customized applications for situations where standard unit configurations are not applicable.
