The Wacker Neuson Plunger Assembly HMS is a genuine OEM component designed for the BV50A-H Backpack Vibrator series. Sourced directly from Wacker Neuson, this assembly is manufactured to the same specifications as the original part, ensuring a correct, no-guesswork installation. Whether you're servicing a BV50A-H unit on an active pour or getting a machine back into rotation between jobs, this is the verified replacement to reach for.
Key Features
- Genuine OEM Plunger Tolerancing — Built to the exact stroke and dimensional spec of the original plunger assembly, maintaining consistent vibration output critical to concrete consolidation performance.
- Direct-Fit for BV50A-H Backpack Vibrators — Confirmed fitment for BV50A-H models; drops into the housing as a matched assembly with no improvised adaption needed.
- Authorized Wacker Neuson Part — Supplied as a genuine OEM assembly under part number 5200019312, backed by Wacker Neuson's parts program for traceability and authenticity.
- Restores Full Vibration Amplitude — A worn or damaged plunger causes irregular frequency and loss of consolidation depth; replacing with the correct assembly brings output back to spec.
- Assembly Format Saves Service Time — Supplied as a complete plunger assembly rather than individual components, so technicians can swap the unit in a single step and return the vibrator to service faster.
The plunger assembly is the reciprocating heart of a backpack concrete vibrator, converting motor-driven motion into the high-frequency vibration that consolidates fresh concrete and drives out air voids. When the plunger wears, loses clearance, or fails, vibration amplitude drops and the vibrator can no longer achieve the penetration depth or frequency needed for proper consolidation — leading to weak spots or honeycombing in the finished pour. Replacing the assembly with a correctly spec'd OEM unit restores the vibrator's full working performance and extends the service life of the surrounding housing components.
