Controlling A Linear Pump


Recommended Posts

Does anyone know an easy way to control the speed of a Gast DDL80 Linear Pump from a DC power source (150 to 300 VDC) using an analog or digital control from a micro controller? The control range needs to cover the full range of pump operation but does not need to be that accurate.


My initial approach is to build a full bridge PWM sine inverter but I was hoping for somthing simplier.


The pump is 120VAC 60HZ 1.8A. The spec is here http://www.gastmfg.com/linear.html
