The Multiquip 2024853 Gear Shaft is a genuine OEM component designed for Multiquip and STOW diaphragm pump models including CA90749, MQ-D206H, MQ-D305, D306, MQ-D306HA, SDP-2, and SDP-3. As an OEM part, it is manufactured to the exact tolerances required to maintain proper meshing, load transfer, and pump timing in these diaphragm pump units. DHS Equipment stocks this part to help keep your pump running at full capacity with a direct, like-for-like replacement. Confirm your model code against the fitment list before ordering to ensure you receive the correct shaft for your application.
Key Features
- OEM-Grade Tooth Geometry — Manufactured to exact pitch and tooth profile specifications, ensuring correct gear engagement and smooth torque transfer within the pump drive train.
- Direct Drop-In Replacement — Matches original shaft dimensions and interface points, so the component seats and aligns correctly without machining or modification.
- Broad Diaphragm Pump Compatibility — Confirmed fitment for CA90749, MQ-D206H, MQ-D305, D306, MQ-D306HA, SDP-2, and SDP-3 diaphragm pump models.
- Consistent Pump Stroke Timing — A correctly functioning gear shaft maintains synchronized diaphragm cycling, sustaining steady flow rate and discharge pressure across the pump's operating range.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, part 2024853 carries the same material grade and dimensional quality as the component originally installed at the factory.
The gear shaft is a core drive component within a diaphragm pump's gearbox, transmitting rotational force from the engine or motor to the eccentric mechanism that drives the diaphragm back and forth. This reciprocating motion creates the alternating suction and discharge strokes that move fluid through the pump. When a gear shaft wears, chips, or fails, the drive connection is lost or becomes erratic, causing reduced output, irregular flow, or a complete loss of pumping action — making prompt replacement essential to restoring full pump performance.
