Power generation equipment

The Graham liquid ring vacuum pump supplied to the power industry for condenser venting is a two-stage (two impeller) design housed in a single pump body. Our unique internal spray feature ensures the maximum amount of condensing before the gas enters the vacuum pump, much like a direct contact condenser. This feature allows the pump to handle more load because condensation ahead of the pump reduces volumetric flow rate.

To achieve capacity requirements, some companies utilize a spray tee ahead of the vacuum pump and air ejector to achieve the design pressure, or even attach a second stage impeller housing to a single stage pump.

All Graham condenser venting equipment is designed to perform per HEI. At Graham, every condenser exhauster system we sell is designed to meet the venting capacity requirements specified per HEI at 1 inch HgA.

Graham is the only manufacturer that builds steam surface condensers, liquid ring vacuum pump venting systems, and liquid ring vacuum pump waterbox priming systems. With such a diverse offering of equipment specifically designed for the power generation industry, by people who understand how these systems function together, why go anywhere else?
