Why Use A Vacuum Pump? Shipco® Pumps Installing a vacuum pump in steam condensate return system removes the air efficiently out of return piping. This enables the condensate to return more rapidly to the boiler feed unit or condensate vacuum unit. This reduces energy consumption and cuts boiler room operating costs. Performance of heating units can be significantly improved as well. Benefits of Steam Vacuum Pumps & Condensate Systems | NES ... There seems to be a common misconception among operators of low pressure steam heating systems that the purpose of the vacuum is "to draw the condensate back". In a properly designed system, the condensate flows by gravity to the receiver, with one exception. There may be times when the vacuum pump is called upon to lift condensate. Steam Generation Upgrade with Vacuum Condensate Pump System In these situations, the vacuum pump is designed to remove the trapped air in the return piping, forming a vacuum that helps the condensate drain back to the mechanical room. The condensate is then transferred back to the boiler feed system to be reused for the generation of steam. The previous vacuum pump system used a “liquid ring” style pump, but the cooling water was not reused. Why Use Vacuum Pumps nash jennings htg The main reasons for having vacuum pumps on low pressure steam condensate return lines are AIR REMOVAL and PRESSURE REDUCTION. During mild weather when the boiler is on only part time, the vacuum pump’s main job is to mechanically remove air from the system so we don’t have to use steam pressure to push air out. The 25 steps in the repair of a vacuum steam system The red hot condensate slugs into the vacuum pump, and flashes into great puffs of expansive steam as it hits the pump’s impeller thereby causing the pump to run dry. In a few hours, the pump’s mechanical seal cracks and spews lava like condensate across the boiler room floor. What is Vacuum Steam? | TLV A Steam Specialist pany ... Vacuum steam is generally generated at higher pressures after which pressure is reduced by using equipment such as an inlet control valve. A vacuum pump is also usually used to help achieve lower pressures at start up and enable the smooth release of condensate. Vacuum pumps solve a lot of steam distribution problems ... The steam’s pressure pushes and overcomes piping and fitting frictional resistance, while the vacuum pump pulls the air through from the return side. Because of this, the engineer probably sized the pipes to be one size smaller than they would have to be in a standard steam system without a vacuum pump. Vacuum Condensate Return Pump Series VCD Xylem Applied ... Vacuum Condensate Return Pump Series VCD. The series VCD vacuum heating unit is designed for large systems through 150,000 sq. Ft. EDR. The VCD include durable cast iron receivers, warranted for 20 years against failure due to corrosion. These units feature individually sized and separately controlled vacuum producing pumps...
