Product Compatibility
Match the full AC-5M-MD part number, 230 V supply, frequency, connections and operating point. Confirm fluid compatibility and required flow using the manufacturer curve. The air-cooled motor must remain dry.
When This Part Needs Replacement
Check the intake, strainer, hoses and trapped air before replacing a pump with reduced flow. Inspect the impeller and supports if noise or poor circulation remains after the supply is restored.
Installation Notes
Disconnect power and isolate the fluid circuit before service. These centrifugal pumps are not self-priming: fill the pump and maintain flooded suction. Do not run dry. Follow the motor label, wiring instructions and applicable electrical requirements.

Parts Desk Insight
This is the 230 V model. Check the motor label as well as the pump family before ordering. Published maximum flow and maximum head describe different points on the curve; hose length, lift, fittings and strainers determine the flow your system actually receives. A carbon bushing offers added tolerance to brief loss of liquid, but it is not permission to run the pump dry.
