The Multiquip A0100370175 is a genuine OEM Carr Bolt 3/8" x 1-3/4" SDP-2 designed for the STOW Diaphragm Pump SDP-2. As a factory-authorized replacement, this bolt meets the exact material and dimensional specifications Multiquip requires for proper assembly and secure fastening on the SDP-2. Sourced directly through Multiquip's OEM parts program, the part delivers the fit and holding strength the original design calls for. If you're servicing or rebuilding your SDP-2 diaphragm pump, using the correct OEM hardware ensures every joint and connection performs as intended.
Key Features
- OEM-Grade Fastener Material — Manufactured to the exact alloy grade and tensile strength specified for the SDP-2 pump assembly, ensuring secure clamping force under continuous pump operation.
- Exact Dimensional Match — 3/8" diameter by 1-3/4" length carriage bolt profile matches the original bolt seat and thread engagement in the SDP-2 housing — installs directly into existing hardware positions.
- Confirmed SDP-2 Fitment — Verified genuine OEM replacement for the STOW Diaphragm Pump SDP-2 series; cross-reference part number A0100370175 before ordering to confirm your application.
- Structural Integrity Under Pump Vibration — Diaphragm pumps generate constant cyclical vibration during operation; an undersized or incorrect bolt can work loose over time, compromising casing alignment and seal integrity.
- Direct Multiquip OEM Part — Supplied as a genuine Multiquip component, not a generic substitute, so you maintain the assembly tolerances the SDP-2 was engineered to operate within.
A carriage bolt in a diaphragm pump assembly serves as a primary structural fastener, clamping pump housing sections, cover plates, or mounting flanges together under the mechanical stress of continuous pumping cycles. On the SDP-2, maintaining correct bolt specification is critical — an incorrect length can result in insufficient thread engagement, while an incorrect grade can lead to stretch or failure under vibration load. When a fastener fails or is substituted with an incorrect size, casing gaps can develop, disrupting the sealed chamber the diaphragm relies on to generate suction and discharge pressure.
