The Wacker Neuson Diaphragm is a genuine OEM component designed for the RCP-12 and RCE-16 series rebar cutters, including 120V, 115V, and 230V variants. Sourced directly from Wacker Neuson, this diaphragm meets the exact material and dimensional standards of the original part, ensuring consistent performance in the hydraulic circuit of your cutter. It is confirmed compatible with the RCP-12/230 50 Hz, RCP-12/120 60 Hz, RCP-12/115, RCE-16/230, RCE-16/120, and RCE-16/115 models.
Key Features
- OEM-Grade Membrane Material — Manufactured to Wacker Neuson's original compound and thickness specification, delivering the flex fatigue resistance a diaphragm in a hydraulic rebar cutter demands.
- Drop-In Replacement — Matches the original bore diameter and sealing bead profile, so the diaphragm seats correctly in the pump chamber without adaptation or trimming.
- Broad Series Coverage — Fits the full RCP-12 and RCE-16 rebar cutter range across 115V, 120V, and 230V configurations, covering both 50 Hz and 60 Hz models.
- Consistent Cutting Power — A correctly functioning diaphragm maintains the hydraulic pressure needed to drive clean, full-stroke cuts through rebar; a cracked or fatigued diaphragm causes pressure loss and incomplete cuts.
- Hydraulic Seal Integrity — Proper diaphragm condition is critical in a hydraulic cutting tool — fluid bypass from a failed diaphragm can contaminate internal components and lead to further pump damage.
The diaphragm is a flexible membrane that forms the pumping and sealing heart of the hydraulic circuit in an electric rebar cutter. As the motor cycles, the diaphragm flexes to build and release hydraulic pressure, driving the cutting blade through rebar cleanly and repeatedly. When the diaphragm cracks, hardens, or tears, pressure drops, cutting force becomes inconsistent, and continued operation risks fluid leaks and broader pump damage — making timely replacement essential to keeping the tool performing at spec.
