Ingersoll Rand says these are highly reliable and cost-effective pumps that bring a unique advantage to oil and gas applications, as well as marine operations, because they are efficient, resilient and can tolerate wide fluctuations in temperatures. The company adds that ARO Pro Series pumps easily transfer, recirculate and batch material ranging from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids, as well as pass large particles without damage. The Hytrel diaphragm at the heart of the pump facilitates material transfer in oil, gas and marine applications because Hytrel, a super-tough thermoplastic polyester elastomer, resists hydrocarbon, hydrogen sulfide, oils, solvents and other industrial chemicals. The ability of the Hytrel diaphragm to adapt to wide temperature variables make it a good choice for onshore and offshore oil and gas applications that exist both in hot desert environments as well as cold, salty, damp marine environments. The elastomer-based diaphragm also naturally resists corrosion and rust. ARO Pro Series pumps offer operators the ability to vary the flow outlet from 12 gallons per minute to 237 gallons per minute and support discharge pressure from 100 to 120 PSI, depending on the size of the pump. The pump is available in aluminum, cast iron and stainless steel – all which can be grounded for enhanced safety in combustible and hazardous environments. Six different pump sizes are available ranging from half-in to three-in.
