SUN Automation Group’s Electra-Flow Electric Ink Pump is a patent pending, electrically powered, double diaphragm pump that has all the qualities of an air-powered ink pump while offering a cleaner, safer and more cost-effective operation. The pump was introduced at CorrExpo 2019 in Denver, Colorado, October 14-16.
The inherent design of the ink pump eliminates the need for costly air consumption and associated pneumatic plumbing and valves required for air-powered pumps and lowers maintenance and material costs. It uses a low-voltage DC motor in a reciprocating motion to oscillate opposed diaphragms. The two pump heads are timed so that one head is taking liquid in while the other is expelling. As a result, pump pulsations are minimized due to the smooth reversing action of the crank mechanism. The pump is available as a stand-alone kit or can be integrated into ink system controls.
With variable motor speeds, users can adjust the flow volume from 0-10 gallons per minute and are ensured a consistent and predictable flow rate at any level. The low-voltage design further reduces energy consumption and increases operator safety. In addition, its self-priming, positive displacement features enable corrugated paper scraps and high-viscosity inks to freely pass through the system — eliminating stalls and further reducing maintenance requirements.
“We pride ourselves on creating customer-centric innovations and the Electric Ink Pump is further evidence of that,” says Greg Jones, Vice President of Global Sales & Aftermarket at SUN Automation Group. “It’s an immediate and effective response to the high costs and inefficiencies associated with traditional air diaphragms.”
