Graco will display its E-Flo DC electric circulating pumps designed to operate by maintaining either constant pressure or a constant flow rate. According to the company, the electric pumps are more efficient than similarly sized pneumatic pumps, resulting in lower electric costs. The E-Flow DC uses a highly efficient electric motor to maintain constant fluid pressure, and its Dual Control technology uses less energy to provide more consistent finishes, the company says. An integrated runaway protection system protects the pumps from premature wear, reducing costly material loss and maintenance while increasing the pump’s longevity. The pumps are said to be easy to install, requiring single-phase, 110/220-V, 50/60-Hz power without variable frequency drive.
Graco also will showcase its ProMix PD2K positive displacement proportioner.
