The Multiquip SP4853 Shaft Gear is a genuine OEM component designed for the SDP-2 STOW Diaphragm Pump. As a direct OEM replacement, this shaft gear meets the original design specifications and installs exactly as the factory-fitted part. Sourced directly through Multiquip's authorized parts network, the part is the correct choice when replacing a worn or damaged drive gear on SDP-2 series pumps.
Key Features
- Genuine OEM Gear Tolerancing — Machined to the original gear tooth profile and dimensional specs, ensuring proper mesh and torque transfer within the pump drive train.
- Direct Drop-In Replacement — Engineered to mount directly onto the shaft assembly of the SDP-2, matching the original bore, keyway, and gear geometry without alteration.
- Confirmed SDP-2 Fitment — Verified for use with the STOW SDP-2 Diaphragm Pump series; verify your model against part number SP4853 before ordering.
- Maintains Drive Efficiency — A properly seated shaft gear sustains consistent diaphragm cycling speed and output pressure; a worn gear leads to slippage, irregular pumping, and accelerated wear on mating components.
The shaft gear is a core power-transmission component within the diaphragm pump's drive system. It transfers rotational force from the motor shaft to the pump mechanism, converting engine output into the reciprocating motion that drives the diaphragm and moves fluid. When the shaft gear becomes worn, chipped, or stripped, the drive connection weakens — causing inconsistent flow, loss of prime, and increased stress on surrounding gearbox components. Replacing it promptly with the correct OEM part restores full pumping performance and protects the integrity of the surrounding drive assembly.
