Electronic Interface Pump

Available in 8 sizes, from 1/4" to 3"

The ARO Electronic Interface Pump is an air-operated diaphragm pump that provide accurate, electronically controlled dosing. Paired with the ARO Controller, ARO Electronic Interface Diaphragm pumps assure consistent flow rates and pinpoint control for a myriad of fluids and applications, from chemical treatment to commercial laundry. 

Hazadous Duty Ready;

  • 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 
  • 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
  • Built-in solenoid control seamlessly integrates with other electronic components
  • Internal cycle counter and end-of-stroke pressure signals track end-of-stroke feedback and pump data
  • Leak detection option detects diaphragm failure to help reduce costly production downtime
  • Factory-installed cycle counter and leak detection kits
  • Preassembled components for hassle-free and error-proof installation
  • Lube-free design and fewer parts for easy maintenance and repairs
  • Multiple sizes accommodate virtually any process, fluid or viscosity
  • Five-year warranty


  • Closed loop system achieves dispensing repeatability within +/- 1%
  • Safe control and monitoring via remote operation
  • Multi-pump control for accurate two part batching processes
  • Controller accepts leak detection, liquid level sensing and proportional control
  • Remote triggers and alerts send operating data, can perform auto shut-down, and keep you up-to-date on maintenance needs
  • Seamless integration between the ARO® Controller and EXP Series Electronic Interface pumps


  • 120VAC, 110VAC and 60VDC
  • 12VDC, 24VAC and 22VAC
  • 240VAC, 220VAC and 120VDC
  • 24VDC, 48VAC and 44VAC
ATEX Compliance
  • To meet ATEX Zone 1 requirements, three solenoid options are available: 12VDC, 24VDC and 220VAC.
No-Coil Solenoid
  • For customers who prefer to use our solenoid with their own coil.
Standard Valve Block
  • Standard Electronic Control Diaphragm pump without solenoid control. Offers the option to add add leak detection and end-of-stroke cycle sensing.
Leak Detection Sensors
  • Refractive infrared light sensors continuously monitor the air-side of the diaphragm and signal if fluid enters the air side of the diaphragm housing.
Cycle Sensors
  • Optional cycle sensors provide closed contact output to monitor pump operation and provide end-of-stroke data on cycle and flow rates. They also help provide preventive maintenance reminders.

Markets & Applications:

  • The ARO controller and electronic interface pumps are ideal for a wide array of applications such as batching, and container and tank fill in numerous markets.
