Extrusion pumps are frequently put in the most difficult of applications: moving high viscosity fluids. Extrusion pumps are used to apply a bead of material. In some instances the pump supplies a continuous bead; other applications call for intermittent delivery. Typical high-viscosity fluids pumped include caulkings, heavy lubricants, mastics, sealers and inks
Ingersoll-Rand/ARO Diaphragm Pumps provide stall-free, ice-free operation. The patented "Unstallable" unbalanced air valve design avoids stalling issues associated with other pumps. The "Quick-Dump" exhaust valves divert cold exhaust air from ice-prone components, preventing freezing. Backed by a five-year warranty, you have the most reliable pump line on the market today.
