The Allied Gomco 01-90-3603 is a specialized 5M Ohm potentiometer designed for the electronic timing control board in Gomco 6000 and 6010 series gastric drainage pumps. This precision electrical component allows the unit to accurately regulate the intermittent suction cycles (90 seconds "on" and 30 seconds "off") that are characteristic of thermotic drainage therapy. It is an essential repair part for units experiencing timing failures or inconsistent suction cycles. As an OEM component, it ensures the exact resistance required to interface with the pump's solid-state circuitry, maintaining the clinical accuracy of the drainage process.
