The Multiquip SP4771 Pump Frame is a genuine OEM component designed for STOW diaphragm pump models SDP-2, CA90749, and SDP-3. As a direct OEM replacement, the SP4771 is manufactured to the same specifications as the original part, ensuring a correct fit within the pump assembly. DHS Equipment sources this part directly through authorized Multiquip channels, so you can order with confidence knowing you are receiving an authentic component. Verify your model code against the fitment list — SDP-2, CA90749, and SDP-3 — before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, ensuring the structural integrity and dimensional accuracy required for a diaphragm pump frame.
- Drop-In Installation — Matches the original mounting points and bolt pattern of the pump assembly, allowing straightforward installation without modification to surrounding components.
- Confirmed Fitment — Directly compatible with STOW diaphragm pump models SDP-2, CA90749, and SDP-3.
- Structural Support for Pump Operation — The frame is the primary load-bearing housing of the pump; a cracked, bent, or worn frame compromises alignment of internal components and leads to accelerated wear across the entire pump assembly.
The pump frame serves as the structural backbone of the diaphragm pump, housing and aligning all major internal components including the diaphragm, valves, and drive mechanism. Without a sound frame, proper sealing and component alignment cannot be maintained, leading to reduced pumping efficiency, fluid leaks, and premature failure of internal parts. Replacing a damaged or compromised frame with a genuine OEM part like the SP4771 restores the pump to its original operating condition and protects the components mounted within it.
