Graco's Core E1 Transfer Pumps Kit communication is made possible through the included Controller Area Network (CAN) cable, allowing real-time data exchange between the pumps and the Reactor unit. The Transfer Pump Controller automates pressure balancing, detects empty drums, and supports on-ratio spraying with fewer manual adjustments. With its compact design and integrated functionality, the 26D006 kit supports efficient material transfer and operational consistency in professional spraying environments.
