Four reasons why electric motors are the greener solution

Moving from air to electric is a key strategy for industrial manufacturing companies to reduce costs and their environmental footprint. Electric motors are more efficient and offer a higher performance than their equivalent pneumatic motors. Many companies are phasing out pneumatic motors because they realise that air is the most expensive commodity in their plant.

The return on investment for an electric-driven system is quite fast. This fast ROI can be directly attributed to its low maintenance needs and its high quality & precision of dispense. 

From the performance logs and digital nature of an electric motor, a wealth of information is available. This can be used to take actions externally and remotely via the PLC control. It also means that electric motors become key components in your Industrial Internet of Things (IoT). This is not the case with pneumatic motors. 

Air compressors and pneumatic pumps are generally extremely noisy, creating environmental working concerns for operators. The systems and pressure pulses from compressors are quite severe, and noise levels can exceed 105 dB(A). Electric motors are quieter than pneumatic motors, typically operating at less than 70 dBa, and will reduce noise levels in your industrial facility to create a healthier working environment. 

Graco makes a line of electric sealant and adhesive equipment, which offer all of the benefits described above. Three popular products are:

• The E-Flo SP electric pumps and supply pumps are designed for industrial and automotive sealant and adhesive applications. This advanced pump will drastically increase efficiency, improve system control capabilities, optimise process performance, and provide critical performance data.
• The E-Flo iQ one component metering and dispense system greatly simplifies the robotic application of sealants and adhesives.
• The Electric Fixed Ratio (EFR) meter, mix and dispense system is an electrically driven proportioner for two-component sealant and adhesives. The EFR provides advanced material control in applications requiring consistent shots and beads.
