Chopper Hopper

The Chopper Hopper, a combined solids reduction and transfer pumping unit, uses the latest in muncher technology to save energy and complete efficient transferring of biofuel.


The powerful all-in-one Chopper Hopper™ unit can homogenize objects such as whole fruits, vegetables, and meat products into a pumpable puree. Fierce cutting blades combined with second- and third-stage grinding shred solids as big as whole watermelons down to a particle size of less than 1 in. in a single pass. The design of this progressing cavity pump allows for low friction of the gear joint design, leading to less wear and better overall performance.
