IR ARO EXPert Series Diaphragm Pumps

The new ARO EXP represents the very latest in air-operated diaphragm pump design expertise with a host of innovative features that can help the process professional solve performance issues while reducing operating costs. Starting with its patented stall-free air valve technology, the ARO EXP offering brings air- operated double diaphragm pump reliability to new levels with a simplified major shift valve and housing that provides stall-free operation within a design that’s been reduced to only 4 working parts. This new simplified air valve arrangement makes access, inspection and scheduled service faster and easier than ever, which translates into saved time, parts and labor costs.

The new ARO EXP air motor design features both a patented anti-ice valve configuration as well as a trip-rod design that insures a positive shift every time. Like the major shift valve arrangement, these ice-free, positive trip-over features also translate into serious savings realized through reduced pump “downtime”.

EXP was built specifically for the process industries and includes a broad range of sizes from ½” to 3”.  ARO provides a comprehensive offering in materials of construction for the ultimate in chemical/fluid compatibility.

Total Cost of Ownership: A 5-Year Snapshot

Competitive Total Cost of Ownership Chart:

Over the five-year service life of a air-operated diaphragm pump, a competitor's initial low purchase price is a misleading portion of the pump's total cost of ownership.

IR ARO EXP Pumps Reduce the Total Cost of Ownership

The Cost Chart for EXP pumps is considerably smaller for some very important reasons:

• Energy Efficient - ARO EXP Pumps are up to 40% more efficient than competitive pump models.
• Downtime Reduction - The Mean Time between Failure ARO EXP is up to four-times longer than competitive pumps.
• Installation/Repairs and Spare Parts - ARO EXP diaphragms provide up to four-times the life of competitive diaphragms and spares include cost-effective service kits. These kits are not like the expensive, full-motor replacements of some competitors.
• ARO EXP Total Value Proposition - ARO EXP provides the BEST Total Cost of Ownership of any diaphragm pump on the market today.

What does this mean to my bottom line?

ARO EXP double diaphragm pumps are up to 40% more efficient than competitive models!
