Abstract: A peristaltic pump includes a pumping mechanism cover releasably coupled to a pumping mechanism base or gear case cover and configured to enshroud components including a roller assembly and tube. Removal of the pumping mechanism cover exposes the components to facilitate maintenance. The pumping mechanism cover may be locked into a closed position using a threaded bushing or a pivoting latch. A plurality of engagement studs may be provided to secure the pumping mechanism base to the gear case housing cover. The pumping mechanism base or gear case cover is configured for releasably engaging tubing inlet and outlet fittings. Thus, tubing may be installed or removed without having to disassemble or remove any other portion of the pumping mechanism base.
