Abstract: A modular multi-channel syringe pump assembly includes a chassis in which are mounted two or more parallel syringe banks. Each syringe bank includes a syringe for retaining a fluid in a chamber with a syringe plunger for drawing fluid into or forcing fluid out of the chamber. A syringe drive actuator includes a syringe drive motor and a mechanical linkage for activating the syringe. At least one position sensor detects syringe position and generates a position signal corresponding to the syringe position. A controller receives the position signal for each syringe bank and generates control signals for operation of the two or more syringe banks.
