The Wacker Neuson Piston Complete is a genuine OEM component designed for DS70Y and DS70 series diaphragm slurry pumps. Sourced directly from Wacker Neuson, this assembly meets every original specification, ensuring a drop-in fit with no guesswork on compatibility. It is confirmed to fit the DS70Y 13in () and DS70Y 13in LRC () pump configurations. When you need a dependable, long-lasting repair, the OEM piston assembly is the benchmark replacement for these machines.
Key Features
- Genuine OEM Displacement Accuracy — Manufactured to Wacker Neuson's exact bore dimensions and material grade, so the piston delivers the correct stroke volume and maintains pump output from day one.
- Direct-Fit Replacement — Matches the original mounting geometry and sealing surfaces of the DS70Y and DS70 pump housing, allowing straightforward installation without machining or adaptation.
- Verified DS70 Series Compatibility — Confirmed fitment across DS70Y 13in and DS70Y 13in LRC pump models, covering both standard and low-residual-content configurations.
- Restored Pumping Performance — A worn or damaged piston causes loss of suction, reduced flow rate, and uneven slurry handling; replacing it with this assembly restores full rated output and consistent operation.
- Pressure-Cycle Durability — Built to withstand the repetitive hydraulic loading of diaphragm pump duty cycles, resisting wear and deformation over extended service intervals.
The piston is the reciprocating heart of a diaphragm slurry pump, generating the alternating pressure and vacuum that draws fluid in and forces it out with each stroke. In DS70 series pumps, the piston drives the diaphragm through its full range of motion, so its dimensional integrity directly controls flow rate and suction lift. When a piston wears, cracks, or loses its sealing fit, the pump loses prime, output drops, and the diaphragm can be subjected to uneven stress that shortens its service life as well.
