The Multiquip 2024852 11 Tooth Pinion is a genuine OEM component designed for MQ and STOW diaphragm pump models including D306, MQ-D206H, MQ-D305, MQ-D306HA, SDP-2, SDP-3, and CA90749 series equipment. As a direct OEM replacement, it delivers the exact tooth count, gear geometry, and material specification required to keep the pump drive train operating as intended. Sourced directly through Multiquip's authorized parts network, the part is the correct service part to specify when replacing a worn or damaged pinion on these diaphragm pump models. DHS Equipment stocks genuine Multiquip parts so you get the right component without the guesswork.
Key Features
- Exact OEM Tooth Specification — Manufactured to the precise 11-tooth count and gear profile required by the original drive assembly, ensuring correct mesh and power transfer.
- Direct Drive Train Replacement — Designed to install directly into the existing pump drive housing with no modification to mating gears or shafts.
- Broad Diaphragm Pump Compatibility — Confirmed fitment across MQ diaphragm pump models D306, MQ-D206H, MQ-D305, and MQ-D306HA, as well as STOW diaphragm pump models SDP-2, SDP-3, and CA90749.
- Sustained Pumping Performance — A correctly fitted pinion maintains consistent eccentric drive motion, which is essential for steady diaphragm stroke and reliable fluid transfer output.
- Genuine Multiquip OEM Part — Part 2024852 is sourced from the original equipment manufacturer, meeting the same material hardness and dimensional tolerances as the part it replaces.
The pinion is a small-diameter drive gear that meshes with a larger gear or rack within the diaphragm pump's mechanical drive assembly. It converts rotational power from the engine or motor into the reciprocating motion that flexes the diaphragm, creating the suction and discharge strokes that move fluid through the pump. When a pinion wears down or loses teeth, the drive connection becomes erratic or fails entirely, causing loss of prime, reduced flow, or complete pump stoppage. Replacing a worn pinion with the correct OEM part restores the precise gear engagement the pump was engineered to deliver.
