Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional tolerances as the original crank arm, ensuring correct stroke geometry and diaphragm actuation.
- Direct Replacement Fit — Designed to drop into existing MQ Diaphragm Pump housings using the original mounting points, with no rework required.
- Confirmed Fitment — Compatible with MQ Diaphragm Pump series equipment; part number 2025584 cross-references directly to this application.
- Sustained Pump Output — A correctly functioning crank arm maintains consistent diaphragm stroke, preserving rated flow volume and pumping pressure cycle after cycle.
- Fuel and Fluid System Integrity — In diaphragm pump applications, a worn or broken crank arm causes immediate loss of prime and pumping capability, making timely replacement critical to safe and effective fluid transfer operations.
The crank arm is the mechanical link that converts rotational motion from the pump's drive into the reciprocating action needed to flex the diaphragm back and forth. This back-and-forth movement is what draws fluid in through the inlet valve and pushes it out through the discharge — it is the core mechanism behind every stroke the pump produces. When the crank arm is cracked, worn at its pivot points, or broken, the diaphragm loses its controlled stroke, causing the pump to lose prime, deliver inconsistent flow, or stop pumping altogether.
