An apparatus for pumping fluid through a flexible tubing is provided. The apparatus uses an electromagnet to activate upstream and downstream pinchers to control fluid flow. An armature is configured to compress the tubing, and in combination with the pinchers creates a fluid flow in the flexible tubing. Downstream occlusions in the tubing can be detected by monitoring for conditions wherein the armature does not close fully. Upstream occlusions in the tubing can be detected by monitoring for conditions wherein the armature does not open fully. A control module can be incorporated into the device for controlling the movement of the components and monitoring for occlusion conditions. |
