The Multiquip SP3352 Connecting Rod is a genuine OEM component designed for STOW Diaphragm Pump models CA90749, SDP-2, and SDP-3. Sourced directly from Multiquip, this part meets the exact engineering specifications of the original component installed at the factory. The SP3352 is a direct-fit replacement that installs into the pump's drive mechanism without modification, keeping your equipment operating at its intended stroke rate and output capacity. Whether you're performing scheduled maintenance or replacing a worn component, this connecting rod restores proper pump action and protects the surrounding drivetrain components.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional tolerances, ensuring the correct load-bearing capacity for diaphragm pump duty cycles.
- Direct-Fit Replacement — Engineered to drop into the existing connecting rod position on CA90749, SDP-2, and SDP-3 pump models without reworking mounts or hardware.
- Confirmed STOW Diaphragm Pump Fitment — Verified compatible with CA90749, SDP-2, and SDP-3 series STOW Diaphragm Pumps.
- Restores Full Pump Stroke — A correctly functioning connecting rod maintains consistent diaphragm travel, which directly controls flow rate and discharge pressure; a worn or bent rod causes erratic output and diaphragm damage.
- Protects Downstream Components — Proper rod geometry reduces side-loading on the diaphragm and crankshaft bearings, extending the service life of adjacent components.
The connecting rod is the mechanical link between the pump's crankshaft and the diaphragm assembly. As the crankshaft rotates, the connecting rod converts that rotational motion into the reciprocating linear movement that flexes the diaphragm back and forth, drawing fluid in on one stroke and pushing it out on the next. When a connecting rod becomes bent, cracked, or worn at its bearing surfaces, the diaphragm stroke becomes uneven or incomplete, leading to reduced flow output, increased wear on the diaphragm itself, and potential crankshaft damage if left unaddressed.
