Checking to see if anyone has any input on running a small diesel generator with a VFD to power their vacuum pump. We are looking at adding another 3,000taps up the hill. Its at-least 1-1/2 miles from any power, but we can pump the sap down to our exiting collection point. I have a good price on a Kubota 20KW gen set, and was thinking that if using a VFD I wouldn't need to worry about Full Load/Starting Amps and bog down the generator. Looking at the gas powered vacuum pumps they seem to be a daily pain with starting and providing gas. With a Generator I could use an electric releaser on a soft start or another VFD or (Hydra continuous flow releaser maybe?) and pump the sap downhill. This will save on having to upgrade on two storage tanks, and only need one bigger tank at the bottom. We currently are using two Busch Mink 1142 pumps on our lower property and haven't had any issues for the past 5 years in operations.
