McElroy says its new DynaMc Hand Pump (HP) machines provide the power and pressure required to butt-fuse pipes sized 2-in. IPS to 12-in. DIPS (63 mm to 340 mm) with a hand-powered pump. The double-action hand pump, paired with high-velocity cylinders, creates faster carriage speeds for critical opening and closing during the fusion process. The DynaMc 28, 250 and 412 HPs—each available in two- and four-jaw configurations—come with an easy-lift cradle that can be removed to make the machine smaller for tight working environments. The electric facer that comes with the HP units can be loaded from either side of the fusion machine.
