The Multiquip 336009002 Plunger Arm is a genuine OEM component designed for MQD2HA and MQD3HA diaphragm pumps. Sourced directly from Multiquip, this part meets the exact specifications of the original — no guesswork, no compromise. It is confirmed to fit MQD2HA and MQD3HA models, making it a direct drop-in replacement for worn or damaged units. When your pump needs to get back to work, the 336009002 delivers the dependability you expect from an OEM part.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the plunger arm delivers consistent stroke travel and reliable diaphragm actuation cycle after cycle.
- Direct Drop-In Replacement — Matches the original mounting points and pivot geometry of the MQD2HA and MQD3HA, allowing straightforward installation without modification.
- Confirmed Fitment — Verified for MQD2HA and MQD3HA diaphragm pump models, so you can order with confidence.
- Restores Full Pumping Stroke — A worn or bent plunger arm reduces diaphragm travel, cutting flow rate and output pressure; replacing it with 336009002 restores the pump to its rated performance.
- OEM Part Number Accuracy — Part number 336009002 matches Multiquip's official parts documentation, eliminating substitution errors during ordering or servicing.
The plunger arm is the mechanical link between the pump's drive mechanism and the diaphragm. As the engine or motor turns, the plunger arm converts rotational motion into the back-and-forth movement that flexes the diaphragm, creating the suction and discharge action that moves fluid through the pump. When the plunger arm is bent, cracked, or worn at its pivot points, the diaphragm stroke becomes inconsistent or stops entirely, resulting in reduced flow, loss of prime, or complete pump failure. Replacing this component promptly keeps the pump operating at its designed output and prevents secondary damage to the diaphragm and valve assemblies.
