The new APEX is an optimized pump designed to suit all dosing, metering and transfer duties between 0.7 and 317 gph. These hose pumps are suited for handling difficult fluids—corrosive, viscous, shear-sensitive, gaseous, crystallizing or fluids—with a combination of these properties. The models feature three pumps in one, with a single pump body adjustable for three hose sizes (10, 15 and 20 mm) when production volumes rise.
