The Multiquip SP3417 Gear 85 Tooth Internal SDP-2 is a genuine OEM component designed for SDP-2 STOW diaphragm pump equipment. This internal gear is sourced directly through Multiquip's authorized parts program, ensuring it meets the exact specifications of the original component. If you're running an SDP-2 diaphragm pump and need a drive gear replacement, the part is the correct OEM part for the job.
Key Features
- OEM-Grade Tooth Profile: — Machined to the original 85-tooth internal gear specification, maintaining correct mesh engagement and drive ratios within the pump mechanism.
- Direct-Fit Replacement: — Engineered to install into the SDP-2 gear housing the same way the original component does, with no modification to mating parts.
- SDP-2 Diaphragm Pump Compatibility: — Confirmed fitment for SDP-2 STOW diaphragm pump models; always verify your model and serial number before ordering.
- Sustained Drive Efficiency: — A correctly functioning internal gear maintains consistent diaphragm stroke timing; a worn or broken gear results in erratic pumping output or complete pump failure.
- Genuine Multiquip OEM Part: — Supplied as an authorized OEM replacement, so the material grade and tooth geometry match what left the factory originally.
The internal gear in a diaphragm pump is a core part of the drive train that converts rotational power into the reciprocating motion needed to actuate the diaphragm. In an 85-tooth internal gear configuration, the gear meshes with a smaller drive pinion to transfer torque at the correct speed and force for consistent fluid displacement. When this gear wears or fails — through tooth damage, cracking, or excessive play — the diaphragm stroke becomes inconsistent or stops entirely, leading to loss of pumping capacity. Replacing it with the correct OEM gear restores full drive function and protects the surrounding drivetrain components from secondary wear.
