Wacker 5000119411 O-Ring (Volute) | PT3 (New Style)

The Wacker Neuson 5000119411 is a genuine OEM O-Ring designed for the PT3, PT3A, PT3H, and PT3V series self-priming centrifugal trash pumps, as well as BPS1550Gw-c and BPS2050Gw-c vibratory plate compactors. As a genuine Wacker Neuson part, the part is manufactured to the exact material grade and dimensional tolerances required for proper sealing in its respective application. Sourcing the correct O-Ring by 5000119411 is critical — an incorrect size or material grade will result in fluid leaks, pressure loss, and accelerated wear on surrounding components.

Key Features

• Correct Material and Dimensional Spec — Manufactured to the exact compound and cross-section dimensions specified for this sealing application, ensuring proper compression and fluid retention.
• Genuine OEM Part — Supplied directly through Wacker Neuson's parts program, meaning this is the same O-Ring installed during original assembly — not a generic substitute.
• Broad PT3-Series Fitment — Confirmed fitment across PT3, PT3A, PT3H, and PT3V 75mm/3-inch centrifugal trash pump variants, covering a wide range of machine numbers within the PT3 family.
• Compactor Application Coverage — Also fits BPS1550Gw-c and BPS2050Gw-c vibratory plate compactors, making this a cross-family sealing component stocked for multiple equipment lines.
• Leak Prevention — A failed or degraded O-Ring allows fluid bypass at critical joints; replacing with the correct part restores a proper seal and prevents downstream damage to pump housings, valves, or hydraulic circuits.
• Fluid-System Integrity — In pump and fluid-circuit applications, a compromised seal can introduce air into the system or allow contaminants in, both of which degrade performance and risk component damage — this genuine replacement eliminates that risk.

An O-Ring is a loop-shaped seal seated in a groove between two mating surfaces or around a shaft, designed to block the passage of fluid or air under pressure. In trash pump applications like the PT3 series, O-Rings are used at key junction points — such as pump housings, valve seats, and inspection ports — to maintain the prime and pressure the pump needs to move water and debris efficiently. When an O-Ring degrades, cracks, or is deformed, it loses its compression seal, leading to fluid leaks, loss of prime, and reduced pump output. In compaction equipment such as the BPS series, O-Rings serve similar roles within hydraulic or fuel-system circuits, where a failed seal can cause fluid loss or system pressure drop that affects machine performance.
