In MOST cases with Horizontal split case pumps, the suction flange is larger than the discharge. This may be difficult to see if the pump and piping is completely insulated, so if the pump has gauges, lets hope the discharge gauge reads a higher pressure than the suction gauge when the ...
How to Evaluate VFD Speed Effect on HydraulicsVariable Frequency DriveVariable Frequency DrivesLev NelikPumps & Systems
TheVFDwill try to maintain the speed (RPM) of the fan so that thestatic pressurein the duct at the location of thestatic pressuresensor maintains some minimum set-point, such as 1.25” sp. The static pressure sensor sends a signal to theVFDand the speed of the fan is adjusted according ...
PREVIOSULY HAD PLANET CNC BREAKOUT HOWRVER, ONLY MOVED MOTORS IN ONE DIRECTION COULDNT CHANGE IT. ANY HELP WOULD BE APRECIATED I have a vacuum regulator pump controller that I purchased from you previously. The LCD display is now missing the bottom line of text. Have you run into this iss...
Using a VFD or variable frequency drive Use a converter to convert your single phase power to DC (Direct Current) and then use an inverter to power the motor. From what I read this is your best bet. As one EE notes "You can run a three phase motor from single phase by converting th...

What Is the Difference Between a Soft Start and a VFD?A VFD has some similarities to a soft starter, but there are enough differences to put it in a class of its own. Officially known as a Variable Frequency Drive , a VFD is a motor control device that controls the speed of an AC ...
