High Pressure Air-Operated Diaphragm Pumps Available in 1.5-Inch and 2-Inch Ports

Ingersoll Rand has expanded its EXP Series 2:1 high-pressure air operated diaphragm pump product line to include 1.5-inch and 2-inch ports for lower flow-rate applications. The 2:1 pumps are designed for chemical, pharmaceutical, metallurgical, food and beverage manufacturers and wastewater treatment plants. They provide fluid-handling solutions for high-viscosity applications and manufacturing facilities pushing fluids up vertical lines or through long pipes traveling across large plants.

The 2:1 pump uses the effective surface area of both diaphragms to double the input pressure, making the pump more powerful than one chamber air-operated diaphragm pumps. They have 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.

The SimulShift and Quick Dump valve technologies help increase the 2:1 pump’s durability and reliability. The SimulShift valve provides ultra-positive, reliable shift signals to prevent the pump from stalling, while the Quick Dump valve eliminates moisture from the system to help avert freezing or breaking.
