easy (relatively) to set up and use for fluid transfer ...

A beast of a pump, easy (relatively) to set up and use for fluid transfer from tank to tank. The pump feels like it was built to last, a ton of metal - either cast or steel. The hose connections feel very tight and built to last.

Amazed in IA

"Continuous duty" says it all. this has already saved us hours of time and effort despite how hesitant we were to accept it right out of the box. A lot of small businesses and farms would benefit from the investment here.

Quality unit

Best pump I have had yet. This mounts right up to my tank in the back of my truck. I am able to pump diesel fuel all day long into tractors, and other heavy equipment without even a hiccup.This is a high quality unit and will last under heavy use for many years. If you are on the fence about buying it don't be just get it you won't be disappointed

Labor saver at several points

With the addition of a tank.and cart, this pump has changed several aspects of doing jobs on a farm. The best part is filling the tractor without having to lift a gas can to shoulder height. Best of all, the pump works as expected.
