These pumps are designed specifically for solids handling and incorporate several engineering features that prevent jamming and clogging, the two most common problems in pumping fluids containing solids. These models feature a semi-axial flow impellers that have a large free passage that will handle up to 5.5" diameter spherical solids, depending on pump model. The impeller design has long screw-like vanes for handling long rags and other debris. JJ Series pumps have a cooling jacket and do not require submergence to maintain correct operating temperatures.
