Diaphragm Pumps

ARO's ATEX-certified diaphragm pumps are widely used to pump various light to medium viscosity fluids in chemical processing industries and water / wastewater treatment plants. These ARO pumps feature an unbalanced valve design that eliminates the occurrence of valve centering and pump stall-out even when the inlet pressure is very low. The company manufactures metallic and non-metallic electric diaphragm pumps in different sizes, operating pressures and diaphragm materials.
