5KH33GNA444X Marathon Motors (Regal Rexnord / Leeson) 1/3 HP 1725 RPM 100-120V / 200-240V 48Y Frame Split-Phase Carbonator Pump Motors

Marathon 5KH33GNA444X 1/3 HP Carbonator Pump Motor

The Marathon 5KH33GNA444X is a rugged, high-performance 1/3 HP Split-Phase Carbonator Pump Motor engineered specifically for continuous-duty fluid transfer applications. Built with a durable rolled steel frame and an Open Drip Proof (ODP) enclosure, this motor is the industry standard for driving positive displacement rotary vane pumps, such as those made by Fluid-o-Tech and PROCON. It is an essential powerhouse for commercial reverse osmosis (RO) systems, high-volume beverage dispensers, and advanced water treatment networks that require reliable, continuous mechanical drive for non-pulsating water delivery.

Operating at a standard speed of 1725 RPM (at 60Hz), this versatile single-phase motor features a dual-voltage design, allowing it to be safely wired for either 100-120V or 200-240V electrical systems. It is equipped with a specialized 48Y Frame and an extended front hub specifically machined to securely accept standard carbonator v-band clamps for direct, seamless pump mounting. To ensure maximum operational lifespan and system safety, the 5KH33GNA444X is fitted with permanently lubricated, double-sealed ball bearings and an integrated automatic-reset thermal protector to prevent catastrophic failure in the event of an unexpected system overload.
