APPARATUS FOR INFUSING FLUID

There is described a pump for pumping fluid, the pump comprising: a tube platen; a plunger configured for actuation toward and away from the tube platen when the tube platen is disposed opposite to the plunger; an inlet valve upstream of the plunger configured for actuation between an occluding position and a non-occluding position; an outlet valve downstream of the plunger configured for actuation between an occluding position and a non-occluding position; a cam shaft configured to actuate the plunger, the inlet valve and the outlet valve; a motor operatively coupled to the cam shaft; and a processor operatively coupled to the motor and configured to control the motor, wherein the processor is configured to limit at least one of a rise of the inlet valve, a rise of the outlet valve, and a rise of the plunger to below a predetermined speed. There is also described a method of operating a peristaltic pump.
