Product Instruction:

Remote pump drive unit with compact structure and small footprint, ideal for hand-held or clamping devices
High precision and pulseless delivery, suitable for small liquid volume transfer and handling
7 inch high-definition LCD touchscreen, easily constructs a multi-function system with up to 4 drive units, and each drive unit could have independent parameters.
Multiple work modes, including infusion only, withdrawal only, infusion/ withdrawal, withdrawal/ infusion, and programmable modes, for various applications.
PLC or computer can control multiple drive units through RS485/ Modbus RTU. Each drive unit can be controlled independently with individual parameters.
Parameters can be saved as a method, which can be stored on the controller and imported/exported to a USB flash drive, simplifying the parameter configuration and facilitating parameter sharing between different drive units.
Powerful features, including the lock screen function, three-level access management with password protection, log recording, and electronic signatures, ensure the safety, accuracy, and compliance of operations.
