Key Features
- Genuine OEM Gear Tolerancing — Manufactured to the exact tooth count and pitch specification of the original SDP-2 gear, ensuring proper mesh engagement and smooth power transfer without slop or premature wear.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the SDP-2 gear position, with matching bore, profile, and tooth geometry for straightforward installation.
- Confirmed SDP-2 Fitment — Verified for use with STOW Diaphragm Pump SDP-2 series equipment, eliminating guesswork when ordering replacement drive components.
- Maintains Drive System Integrity — A worn or damaged drive gear causes erratic diaphragm stroke timing and reduced pump output; replacing it with the correct 79-tooth OEM gear restores full pumping performance.
- Long-Term Wear Resistance — Built from materials matching the original OEM specification to withstand the cyclical load demands of continuous diaphragm pump operation.
The drive gear in a diaphragm pump is responsible for transmitting rotational motion from the motor or engine to the pump mechanism that moves the diaphragm back and forth. In an SDP-2 series pump, the 79-tooth gear plays a direct role in setting the stroke rate and maintaining synchronized movement of the pumping assembly. When this gear becomes worn, chipped, or develops excessive backlash, the diaphragm stroke loses consistency, resulting in reduced flow rate, pressure loss, or complete pump failure. Replacing it with the correct OEM-spec Multiquip SP5058 gear restores proper drive engagement and ensures the pump delivers the output it was designed for.
