The Multiquip SP3355A1 Discharge Connection is a genuine OEM component designed for STOW diaphragm pump models SDP-2, CA90749, and SDP-3. As an authorized Multiquip OEM part, the SP3355A1 is manufactured to the exact specifications required for proper pump operation and a secure, leak-free outlet connection. Sourced directly through the Multiquip OEM parts program, this discharge connection delivers the fit and function contractors depend on when keeping diaphragm pumps running in the field. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact material and dimensional specifications, ensuring the discharge port seals and mates correctly under operating pressure.
- Direct Bolt-On Replacement — Engineered to match the original discharge outlet geometry on compatible STOW diaphragm pumps, allowing straightforward installation without modifications to fittings or hose connections.
- Confirmed Fitment — Compatible with STOW diaphragm pump models SDP-2, CA90749, and SDP-3; always cross-reference your model code to verify before ordering.
- Leak-Free Discharge Performance — A properly seated discharge connection maintains full pump output pressure and prevents bypass losses that can reduce flow rate and strain the diaphragm assembly.
- Fluid Handling Safety — A secure discharge connection prevents uncontrolled fluid release at the outlet, an important consideration when pumping aggressive or hazardous liquids common in construction dewatering applications.
The discharge connection is the outlet fitting through which pumped fluid exits the diaphragm pump and enters the discharge hose or piping. It creates a sealed, pressure-rated interface between the pump body and the downstream plumbing, directing flow away from the work area at the volume and pressure the diaphragm assembly generates. When this connection cracks, corrodes, or loses its sealing surface, the pump loses output pressure, leaks at the outlet, and may introduce air into the discharge line — all of which reduce pumping efficiency and can bring operations to a halt.
