This is one of the smallest gravel pump systems that we offer. We offer these in 4″ and 6″. These type of gravel pump can pass up to a 3.5″ sphere on the 4″ pump gravel pumps and 5.5″ sphere on the 6″ gravel pump.
I have personally pumped around 20 yards per hour with the 4″ and the 6″ I have averaged up to 35 yards per hour. The 4″ pump moves up to 1000 GPM. It can pump up to a 30 % solids for a short time. The 6″ pump can pump up to 1600 GPM an up to 30% solids. In theory the 6″ can do up to 100 yards per hour, however I have used several of these in my life time and my averages are around 25 to 35 yards per hour in good material.
