Key Features
- Genuine OEM Bearing Grade — Manufactured to original precision tolerancing standards, ensuring correct load handling and dimensional accuracy for the connecting rod application.
- Direct Drop-In Fit for SDP-2 — Engineered specifically for STOW SDP-2 diaphragm pumps, seating into the connecting rod without modification to surrounding hardware.
- Confirmed SDP-2 Fitment — Verified for STOW SDP-2 series diaphragm pump models — confirm your model code before ordering.
- Sustained Pump Stroke Integrity — A worn connecting rod bearing allows excess play in the rod, leading to inconsistent diaphragm stroke, reduced flow output, and accelerated wear on adjacent components. this part restores consistent reciprocating motion.
- Genuine Multiquip OEM Part — Sold by DHS Equipment as an authorized Multiquip parts distributor, backed by OEM sourcing for part number accuracy.
The connecting rod bearing in a diaphragm pump sits at the junction between the crankshaft and the connecting rod, translating rotational engine or motor movement into the back-and-forth stroke that drives the diaphragm. This motion is what creates the pressure differential needed to draw fluid in and push it out. When the connecting rod bearing wears, it introduces unwanted play into the stroke cycle, reducing pumping efficiency, increasing vibration, and placing additional stress on the crankshaft and diaphragm — ultimately leading to pump failure if left unaddressed.
