Graco’s E-Flo DC dual-control electric circulating pumps are designed to maintain either constant pressure or a constant flow rate in paint finishing applications. They combine the features of pneumatic pumps to maintain constant fluid pressure and provide consistent finishes with the use of a highly efficient electric motor for energy cost savings.
The pumps also feature an integrated runaway protection system that automatically shuts them down if material has stopped flowing to them. This prevents material loss and protects the pumps from premature wear, reducing maintenance and increasing longevity.
The pumps are available in a basic model with two simple control knobs located directly on the pump for easy adjustment of settings, or in an advanced model with a digital control module for additional performance control and the ability to manage multiple pumps from a single module. The advanced pump also can easily integrate with a customer’s PLC network via fiber optics.
