The Multiquip 336009001 Plunger Arm is a genuine OEM component designed for MQD2H and MQD3H diaphragm pumps. Sourced directly from Multiquip, this part meets the exact specifications required to keep your pump operating at full capacity. It is a direct-fit replacement for the original plunger arm, confirmed compatible with MQD2H and MQD3H models. When the original part wears or fails, the 336009001 restores the mechanical stroke action that drives consistent fluid displacement through the pump.
Key Features
- Genuine OEM Construction: — Manufactured to Multiquip's original mechanical tolerances, ensuring the correct stroke length and load-bearing capacity expected of this plunger arm.
- Direct-Fit Replacement: — Engineered to bolt into the original mounting position on MQD2H and MQD3H pumps without modification to surrounding components.
- Confirmed Fitment: — Verified compatible with Multiquip MQD2H and MQD3H diaphragm pump models.
- Sustained Pumping Stroke: — A correctly functioning plunger arm maintains the full mechanical stroke cycle, supporting steady flow rates and preventing irregular discharge pressure.
- Wear-Critical Component: — The plunger arm operates under repeated mechanical stress; replacing a worn arm promptly prevents accelerated wear to adjacent diaphragm and drive components.
The plunger arm is a core mechanical link in a diaphragm pump's drive train. It converts rotational engine motion into the linear reciprocating stroke that flexes the diaphragm, drawing fluid in on one stroke and expelling it on the next. A worn or damaged plunger arm disrupts this stroke cycle, leading to reduced flow output, uneven discharge pressure, and increased stress on the diaphragm itself. Replacing the arm with a correct OEM part restores the full mechanical advantage the pump was designed to deliver.
