Installation Overview for Hazardous Areas:

Installation Overview for Hazardous Areas:

  • Operate the pump in the following hazardous locations:
    NEC / CEC: Class I&II, Div 1&2, Group A-D
    ATEX: Zone 1&2, 21&22
  • Hazardous rated electrical components allow for installation within hazardous areas
  • Wire the provided sensors and barrier devices per your local code requirements
  • Install controller and barrier devices in a suitable hazardous enclosure or outside
    the hazardous area

Use the ARO® Controller or Your Own PLC Controller

  • Remote triggers and alerts send operating data, can perform auto shut-down, and keep you up-to-date on maintenance needs
  • Controller accepts leak detection, liquid level sensing and proportional control
  • Seamless integration between the ARO® Controller and the EXP Series Electronic Interface pumps
  • Multi-pump control for accurate two part batching processes

Now Available: 3″ Non-Metallic EXP Series Diaphragm Pump

ARO has expanded its line of EXP Series pumps with the new 3″ non-metallic diaphragm pump. Designed for chemical and water processing applications, the 3″ 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 pressure.

EXP is Automation Ready

All EXP Series pumps are enhanced with electronic interface capability, providing accurate, electronically controlled dosing. Combine our pump with the ARO Controller or a PLC or PC based system and switch from inaccurate, inefficient manual processes to intelligent fluid management.

  • EXP is compatible with almost any automation system
  • Electronic Interface Pumps are now available for hazardous duty environments (ATEX, NEC, and CEC certifications)
  • Leak detection option certified for use in ATEX/ and NEC/CEC locations detects diaphragm failure to help reduce costly production downtime
  • Internal cycle sensor and end-of-stroke signals track end-of-stroke feedback and pump data
  • Preassembled components for hassle-free and error-proof installation

Exclusive ARO® Quick Dump™ Valve

Our EXP Series diaphragm pumps feature an exclusive to ARO® Quick Dump™ valve that reduces icing by keeping cold exhaust air out of the air motor. This patented feature improves reliability and durability when running your pumps at high speeds to reduce downtime and maintenance.

Solenoid in the Air Valve

What is the advantage?The solenoid actuation allows for accurate cycle rate control and provides a more consistent volume per stroke than is achieved with standard pumps. Additionally, solenoid control allows for a precise number of cycles to be fully completed for improved batch repeatability.

All 1/4″ – 2″ Non-metallic PD pumps are now upgradeable!

PD pumps are manufactured such that solenoid operation, flow monitoring and leak detection functionality can be added at a later date. As your processes mature, this capability allows you to enhance manually operated processes to incorporate additional control and monitoring capabilities. Simply remove two plugs and replace with a proximity sensor and (or) leak detector. Once upgraded, these components can also be integrated with the ARO controller for seamless integration.
