A New Member of the EXP Series Family: 

The Three-Inch Non-Metallic Pump

ARO is expanding its line of EXP Series pumps with the addition of the three-inch non-metallic diaphragm pump, providing you with another great sales opportunity.



Designed for chemical and water processing applications, the three-inch non-metallic pump can transfer up to 285 gpm (1079 lpm) of fluid without causing the type of damage possible from smaller capacity pumps that use higher pressures. This is a key feature for customers who want to maintain fluid integrity. 

 Like all ARO EXP Series pumps, the three-inch non-metallic pump comes process ready with connection points that make future upgrades possible if application needs change. The pump can be enhanced with electronic interface capability to maintain flow accuracy and support automated processing.

3 Inch Non-Metallic Case Study

Customer: Large Plating Company in North America

Application: High volume transfer of a variety of Acids and Caustics

Problem: Customer was not satisfied with the performance of the 3-Inch Yamada® NDP-80. The pumps transfer speed was not satisfactory and the pump was noisy. This application requires a quick transfer of chemicals for their process.

Operating Parameters:

Air Pressure 90 psi

Fluid Temperature ~120°F

Duty Cycle: 20 - 30 hours per week Operation:  Since October

Solution: At 90 psi the ARO® PD30P delivers a 27% increase in fluid transferred at a higher back pressure. The ARO® pump also uses less air and is quieter according to the customer.

Results: The ARO® pump delivers a lower Total Cost of Ownership when compared to the Yamada®. The Yamada pump needs to pump for 10.18 hours to deliver the same amount of fluid that the ARO® pump delivers in 8 hours. This results in the Yamada® pump needing to more than 10,472 additional cycles to pump the same amount of fluid reducing diaphragm life and utilizing more air than the ARO® pump!  

From the Customer: "We are extremely happy with the performance of the ARO® 3" Non-Metallic pump and will consider ARO® as our pump of choice for future needs!"

We're pleased to announce an expansion to the EXP series!

ARO EXP Series diaphragm pumps now include new 3" non-metallic models available in polypropylene or PVDF. The NEW 3" non-metallic models are reliable, efficient and offer a lower Total Cost of Ownership which has made ARO a leading brand in the pumping industry.

Features:

  • Efficient transfer leveraging EXP air motor design
  • Faster transfer, 55% more flow than ARO® EXP 2" Non-Metallic models

Ideal for high volume transfer in industrial, chemical processing and water treatment applications, the EXP Series 3-inch pump can be more efficient against 2-inch models under certain operating conditions, and can offer longer diaphragm life due to decreased cycling rates. Additionally, the ARO® EXP Series 3-inch pump is compatible with harsh chemicals and provides a gentler stroke to prevent damage to fluid in higher volume transfer applications.
