As an authentic Multiquip OEM part, the SP2726TPE is manufactured to the same specifications as the original component, ensuring a direct, dependable fit in your pump. Sourced through DHS Equipment, this part is the correct factory replacement for keeping your STOW diaphragm pump operating at full capacity.
Key Features
- OEM-Grade Flexure Material — Manufactured to original material and dimensional specifications, ensuring the diaphragm maintains proper seal integrity under repeated pump cycles.
- Direct Drop-In Replacement — Engineered to mount in the original diaphragm cavity without alteration, using the same bolt pattern and profile as the factory part.
- Confirmed Fitment for STOW Diaphragm Pumps — Verified compatible with SDP-2, CA90749, and SDP-3 pump models.
- Sustained Pumping Performance — A correctly seated diaphragm maintains consistent flow and pressure; a cracked or fatigued diaphragm causes loss of prime, reduced output, and fluid bypass.
- Fluid Containment Integrity — The diaphragm is the primary barrier between the pumped fluid and the pump mechanism — using the correct OEM replacement is critical to preventing cross-contamination and seal failure.
The diaphragm is the core pumping element in a diaphragm pump, flexing back and forth to draw fluid in through the inlet valve and push it out through the discharge valve with each stroke. It acts as both the motive force and the primary fluid seal within the pump chamber. When the diaphragm cracks, stiffens, or develops pinholes, the pump loses suction, output pressure drops, and fluid can leak into areas of the pump that are not designed to handle it — making timely replacement essential to maintaining pump performance and service life.
