The Multiquip W35C12329CRWI Oil Seal is a genuine OEM component designed for SDP-2 series STOW diaphragm pumps. This is a direct OEM replacement sourced through Multiquip's authorized parts program, ensuring the seal material grade, compression rating, and dimensional tolerances match the original equipment specification exactly. Confirmed fitment for SDP-2 diaphragm pump models makes this the correct choice when servicing your pump and restoring a leak-free seal at the shaft interface.
Key Features
- OEM-Grade Sealing Material — Manufactured to the same material grade and compression specification as the original, ensuring a consistent, leak-resistant seal under operating pressure and temperature.
- Drop-In Shaft Fit — Dimensioned to seat directly into the original housing bore without reworking or shimming, matching the SDP-2 pump's shaft diameter and housing recess.
- Confirmed SDP-2 Fitment — Verified for STOW SDP-2 diaphragm pumps, so you can order with confidence that this is the correct seal for your machine.
- Prevents Oil Migration and Contamination — A correctly seated oil seal keeps lubricant where it belongs and stops external moisture or debris from entering the bearing cavity, protecting internal components from accelerated wear.
- Fuel and Fluid System Safety — A failed or degraded oil seal can allow fluid migration into areas of the pump where it creates a hazard; replacing with a genuine OEM seal restores the integrity of that barrier.
An oil seal creates a dynamic barrier between a rotating shaft and the stationary pump housing, retaining lubricating oil within the bearing cavity while blocking contaminants from entering. In a diaphragm pump like the SDP-2, this seal plays a critical role in keeping the drive mechanism properly lubricated and protected from process fluid intrusion. When an oil seal wears, cracks, or loses its seating compression, oil leaks out, contaminants enter, and bearing life drops sharply — making timely seal replacement one of the most cost-effective preventive maintenance steps on any pump.
