Pamphlet M2404 Mechanical Pump & Pump/ Trap GP Series GT Series

Effective Condensate Processing Improves Plant Efficiency Increased productivity and product quality, plus reduced energy consumption and water treatment are some of the many benefits of condensate drainage and recovery. The GP/GT series provides the perfect solution for optimizing condensate processing in many applications. Prevention of Heat Exchanger “Stall” ¡Stabilized temperature control improves product quality ¡Elimination of water hammer prevents equipment damage and improves safety ¡Prevention of corrosion caused by condensate accumulation ¡Some models are designed for installation...

’s Series— The Total Solution to Heat Exchanger “Stall” Importance of “Stall” Prevention “Stall” prevents condensate from being discharged from heating equipment. It results in: "Stall" occurs and condensate backs up Press. Equip. press. As the “stall” cycle repeats, the steam pressure in the equipment varies above and below the back pressure, causing product temperature and quality fluctuations. Back press. Temp. ¡Process Temperature Swings Set temp. Product temp. Time ¡Water Hammer Damage Water hammer can occur when backed-up condensate re-evaporates, or as incoming hot steam hits cooler...

Benefits Built-in Steam Trap Improves Performance (GT Series) ¡Automatically switches between pump and trap operation, in response to process conditions ¡Internal trap mechanism always matches pump output, with no damage to trap, and eliminates need for sizing ¡No need for external steam trap means simplified compact design and lowered installation costs ¡Trap body and plug are both stainless steel for minimum leakage and maximum life Snap-action Mechanism Maximizes Life Instantaneous Switching ¡Heat-treat hardened stainless steel internals ¡Durable nickel-based alloy compression coil...
