The Bucher 10V Coil is the replacement coil that sits on the directional valve on Bucher hydraulic pumps. The 10-volt rating is intentional, not a typo — Bucher specs the coil to keep operating when the truck's electrical system sags below 12V under load, which is exactly when the pump is working hardest.
Why is the coil rated 10V on a 12V pump?
When the pump motor pulls 100+ amps under load, system voltage at the coil can drop into the 10–11V range — especially in cold weather or with a tired battery. A 12V-only coil might drop out at exactly the moment the cylinder is mid-stroke. The 10V rating gives you margin so the valve stays open while the pump is doing real work.
- 10V replacement coil for valves on Bucher hydraulic pumps
- Rated 10V (not 12V) so it keeps operating during voltage sag — by design
- Sits on the directional valve, not the solenoid
- Direct OEM replacement
- Pierce SKU 1019660
For the solenoid (a different part), see the Bucher 12V Pump Solenoid (Style 2). For the complete valve assembly on the PM-319, see the Bucher Pump Valve (P07193).
