Comparing Condensate Return Pumping Options Webinar

There is more to sizing a pump for condensate return than just understanding the capacity/GPM required for the application. The variables that need to be understood are also different when sizing and selecting an electrical pump versus a mechanical pump. These issues are explored in detail in this webinar. In it, TLV Corporation President Jim Risko explains how to select and use electrical/mechanical pumps; and ensure that condensate return pumping applications operate reliably. 0:00 Introduction 1:08 Electric Atmospheric Condensate Pumps 1:17 Electric Pressurized Condensate Pump Systems 1:32 Simple Condensate Return 2:48 Pumped Condensate Return 3:35 Typical Electric Condensate Pump? 3:51 Electric Pump Selection Criteria 4:04 Electric Pump Requirements 4:58 Flashing Causes Cavitation 5:20 Condensate Pump Cavitation 7:15 Mitigate Impeller Damage 11:01 Condensate Pumps: Electric Requirements 12:06 Actual v Design Pumping Load 16:32 Service Factor / Life Considerations 18:51 Negative Differential / Back Pressure Causes 19:59 Total Dynamic Head (TDH) - Back Pressure 21:18 Total Discharge Pressure (TDP) 23:01 3500 RPM Pump ("High Efficiency") 27:17 3500 RPM Pump Characteristics 28:58 1750 RPM Pump ("Low NPSH") 31:35 1750 RPM Pump Characteristics 33:04 Net Positive Suction Head (NPSHA) 34:09 Water Vapor Pressure Table 34:55 Example: Net Positive Suction Head (NPSH) 36:09 3500 High RPM: NPSHR NPSHA 36:55 Decrease Temperature - Vapor Pressure Table 37:10 Cool Temperature 3500 High RPM: NPSHR 37:37 Elevate Receiver 3500 High RPM: NPSHR 39:00 1750 Low RPM: NPSHR NPSHA 39:52 Flash Steam 40:19 Installation Requirements & Common Errors 42:50 Insufficient NPSHA 47:40 37.5 GPM @ 30 PSIG Electric Condensate Pump 51:14 Proper Installation 52:53 Design & Installation Requirements 53:50 VFD/VSD Motor Drive 56:06 Pressurized Condensate Return Systems 56:36 GP10 PowerTrap Operation 57:53 GP10 PowerTrap Pump 58:32 PowerTrap Pump MOTIVE 59:53 Steam is Wet Find articles referenced and learn more about this topic in the Steam Theory section of the TLV website: https://www.tlv.com/global/US/steam-t...
