33 MARCO self-priming pumps for AC systems SELF-PRIMING CONSTANT FLOW IP67 For systems requiring continuous water circulation. They ensure stable and lasting operation by automatically restoring the flow and thus avoiding the problem of system emptying caused by the vessel's oscillations due to waves and hull inclination. Nickel-plated brass body, stainless steel shaft and PEEK gears, ideal for both fresh and saltwater environments, ensure high wear resistance even under severe operating conditions.
