    Goldstream Pumps originally developed our flagship Monster Series portable pumps to solve a very specific problem: the grueling demands of heavy oil collection and transfer in the biofuel industry. We needed a portable system that wouldn't quit when the fluid got thick and the hours got long.

    Word quickly got out about these great little pumps. Over time, professionals across multiple industries found us and started putting our equipment to work on all sorts of demanding jobs—from daily waste oil collection routes to pumping heavy gear oil high up in wind turbines.

    Today, whether you are running a fleet service truck, a marina, or an industrial facility, our promise is simple: If you have oil that you need to pump from here to there, the Monster pump will get it done.
