The Wacker Neuson Pump Diaphragm is a genuine OEM component designed for the BV35A-P Backpack Vibrator, PV35A Pole Vibrator, P35A and P31A Power Units, and PG1 Dewatering Pump series. As a direct OEM replacement, this diaphragm is manufactured to the same specifications as the original part, ensuring proper sealing and fluid transfer performance across all compatible models. This part covers an extensive range of P35A and P35A EU configurations, making it a reliable stock item for dealers and rental fleets running multiple units. Confirm your model number before ordering to ensure the correct fit for your specific machine.
Key Features
- Genuine OEM Diaphragm Material — Manufactured to Wacker Neuson's original flex and chemical-resistance specifications, maintaining consistent pumping action across the full service life of the diaphragm.
- Direct Drop-In Replacement — Engineered to seat and seal exactly as the original, so installation follows the standard service procedure without any modification to the pump housing or fittings.
- Broad Model Coverage — Compatible with BV35A-P Backpack Vibrator, PV35A Pole Vibrator, P35A and P31A Power Units (including EU variants), and the PG1 Dewatering Pump — ideal for multi-unit fleets.
- Restores Full Pump Output — A worn or cracked diaphragm causes loss of prime, reduced flow, and erratic pressure; replacing it with 5000157493 brings pump output back to spec immediately.
- Fuel System Integrity — The diaphragm forms a critical barrier between the fuel and air circuits in the pump; using a correctly rated OEM part prevents fuel contamination and unsafe operation in wet screed and dewatering applications.
The pump diaphragm is a flexible membrane that creates the reciprocating action needed to draw fuel or fluid through the pump and deliver it at consistent pressure to the engine or discharge point. In vibrator power units and dewatering pumps, this diaphragm cycles thousands of times per minute, and even a small tear or loss of elasticity will cause the pump to lose prime, starve the engine of fuel, or fail to move fluid efficiently. Replacing a fatigued diaphragm promptly keeps the unit running at full output and prevents secondary damage from fuel starvation or air ingestion in the pump circuit.
