Ingersoll Rand Expands EXP Series 2:1 High Pressure Pump Portfolio

Ingersoll Rand, a world leader in creating and sustaining safe, comfortable and efficient environments, has expanded its EXP Series 2:1 high pressure air operated diaphragm pump product line to include 1.5″ and 2″ 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 effective fluid handling solutions for high-viscosity applications and manufacturing facilities pushing fluids up vertical lines or through long pipes traveling across large plants.

Unlike most air-operated diaphragm pumps, 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.

“Based on the success of the 3″ EXP Series 2:1 high pressure air-operated diaphragm pump, Ingersoll Rand determined there was a need for 1.5″ and 2″ port offerings,” said Ken Boyce, product manager — ARO diaphragm pumps, Ingersoll Rand. “We are pleased to provide a safer, more durable and more efficient fluid handling solution for lower flow rate applications.”
