The Wacker Neuson Seal Kit is a genuine OEM component designed for PT6LT, PT6LS, and PT6LS(I) series 6-inch self-priming centrifugal trash pumps. As a factory-sourced kit, it delivers the exact seal geometry, material grade, and compression spec needed to restore a proper fluid-tight barrier inside the pump housing. This kit covers the PT6LT pump with trailer, the PT6LS skid-mounted unit, and the PT6LS(I) — making it the right call for any of Wacker Neuson's heavy-duty 6-inch trash pump configurations. Verifying your model number against part number before ordering ensures you receive the correct seal set for your specific machine.
Key Features
- OEM-Grade Seal Materials — Each seal in this kit is manufactured to the original compound and durometer spec, maintaining proper compression and fluid containment under the high-volume, abrasive slurry conditions these 6-inch trash pumps routinely handle.
- Complete Kit for a Full Pump Reseal — Bundles every required seal in a single part number, so technicians can complete a thorough reseal in one pass without sourcing individual components separately.
- Fits PT6LT, PT6LS, and PT6LS(I) Pump Families — Confirmed fitment across the trailer-mounted PT6LT, the skid-mounted PT6LS, and the PT6LS(I) variant — all Wacker Neuson 6-inch centrifugal trash pump platforms.
- Restores Full Priming and Flow Efficiency — Worn or degraded seals allow air ingestion and internal bypass, causing the pump to lose prime or deliver reduced discharge flow. A fresh seal kit brings the pump back to its rated performance.
- Fluid System Integrity — Proper sealing is critical on high-volume trash pumps handling contaminated water, slurry, and solids. Using the correct OEM seal kit prevents premature wear on the impeller and volute caused by leakage-driven cavitation.
The seal kit in a centrifugal trash pump maintains the fluid-tight boundaries between rotating and stationary components inside the pump casing, preventing water, slurry, and solids from bypassing the impeller or escaping along the shaft. When seals wear or crack — whether from abrasive media, heat cycles, or extended run hours — the pump loses the ability to hold prime, discharge pressure drops, and internal components become exposed to accelerating wear. Replacing the seal kit at the first sign of leakage or suction loss is the most cost-effective way to extend the working life of the pump and keep it operating at rated capacity.
