The Wacker Neuson Intake Valve is a genuine OEM component designed for the PDT2A, PDT3A, and PDI3A series diaphragm pumps. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original valve installed at the factory, ensuring a correct, trouble-free installation with no guesswork. It is confirmed to fit the PDT2A, PDT3A, and PDI3A models, making it a straightforward service solution when an intake valve replacement is due. Keep part number on hand for planned maintenance or unscheduled repairs to get your pump back in service fast.
Key Features
- OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional spec, ensuring the valve seats and seals correctly under pumping pressure without bypassing fluid.
- Direct Drop-In Replacement — Matches the original valve geometry and port sizing, so it installs into the existing valve housing without modification or rework.
- Confirmed Fitment — Compatible with PDT2A, PDT3A, and PDI3A series Wacker Neuson diaphragm pumps.
- Sustained Pump Output — A correctly functioning intake valve maintains proper one-way flow into the pump chamber; a worn or damaged valve causes loss of prime, reduced flow rate, and erratic pump performance.
- Fuel System Confidence — As a genuine OEM part, 5100056873 carries Wacker Neuson's part number verification, so you can order with confidence that it is the correct replacement for your machine.
The intake valve controls the one-directional flow of fluid into the pump's diaphragm chamber on each suction stroke. By opening to allow fluid in and closing to prevent backflow, it works together with the discharge valve to build and maintain pumping pressure. When the intake valve wears, cracks, or fails to seat properly, the pump loses its ability to prime effectively, output drops off, and the machine may struggle to move fluid at all — making timely replacement essential to keeping the pump operational.
