Ingersoll Rand/ARO Diaphragm Pumps provide stall-free, ice-free operation. Their 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, we have the most reliable diaphragm pump line on the market today.
