Multiquip 336009001 Arm Plunger MQD2H - OEM Replacement Part

The arm plunger is a critical mechanical component in diaphragm pump assemblies that transfers rotational motion from the crankshaft to reciprocating motion of the pump diaphragm. This precision-machined component ensures consistent pumping action and maintains proper timing between the drive mechanism and the pumping chamber, directly affecting flow rate and pressure output.

In Multiquip diaphragm water pumps, the arm plunger operates under constant cyclic stress and wear. Signs that replacement is needed include decreased pump performance, irregular pulsation, unusual noise during operation, or visible wear on the plunger surface. Regular inspection of this component during routine maintenance intervals helps prevent unexpected downtime and maintains optimal pump efficiency.

This arm plunger is designed specifically for demanding construction and industrial applications where reliable water transfer is essential. Manufactured to Multiquip's exact specifications, it ensures proper fit and function within the pump assembly.
