Graco E-Flo iQ Tandem Advanced Electronic Flow Control Dispensing System

Graco E-Flo iQ Single Component Tandem Pump System Overview

The Graco E-Flo iQ Tandem System is designed for continuous, high-precision dispensing of sealants and adhesives in automated manufacturing. It features two rams connected via a 3-way block with ball valves and is controlled by a single Advanced Display Module (ADM). Operating identically to the Single E-Flo iQ System, the Tandem System automatically switches to the second ram when the first drum is empty—eliminating downtime and ensuring seamless production flow. With direct drum or pail metering, real-time pressure control, and advanced PLC integration, it’s ideal for high-volume applications requiring uninterrupted material supply.

For applications that don’t require dual-ram functionality, explore the Graco E-Flo iQ Single Component System.

Ambient vs. Heated Configurations

• Ambient Option: Ideal for materials that maintain optimal viscosity at room temperature, requiring no additional heating.
• Heated Option: Designed for temperature-sensitive adhesives and sealants, maintaining consistent viscosity and flow in colder environments or high-performance applications.

E-Flo iQ System Features and Benefits

• Continuous Dispensing with Automatic Switchover: When one drum empties, the system automatically switches to the second ram, ensuring uninterrupted material flow.
• Precision Flow & Pressure Control: Electric servo-driven motor ensures real-time flow adjustments and pressure stability from tank to tip.
• Direct Drum or Pail Metering: Eliminates external dosing systems, reducing complexity and maintenance.
• Versatile Valve & Heating Options: Supports heated (up to 158°F/70°C) and non-heated applications with multiple valve configurations for low- and high-flow needs.
• Advanced Programming & Diagnostics: The Advanced Display Module (ADM) allows setup of up to 16 dispense styles and real-time monitoring.
• Seamless PLC Integration: Connects via EtherNet/IP, PROFINET, DeviceNet, and PROFIBUS for full automation.
• Cost-Effective & Low Maintenance: Fewer components, lower maintenance, and a lightweight hose and valve setup minimize robotic payload requirements.
