Pump Air PressureIngersoll Rand has expanded its EXP Series 2:1 high-pressure, air-operated double-diaphragm pump product line to include 1.5″ and 2″ ports for lower flowrate applications. The 2:1 pumps are designed for chemical, pharmaceutical, metallurgical, food and beverage, and wastewater. They provide effective fluid handling solutions for high-viscosity applications and manufacturing facilities, pushing fluids up vertical lines or through long pipes traveling across large plants. The pumps feature conductive polypropylene air motors to help protect against static electric discharge. The 2:1 pumps also have stainless steel wetted sections to reduce stress and material fatigue, which can potentially cause the pump to leak.
