Millingford Plungers are engineered for optimum performance and long life under the most severe well conditions.
Millingford plungers have a base material of low carbon steel and are available with the following optional features:
- Hard chrome plated outside diameter for abrasive conditions where corrosion is not a factor.
- Metal sprayed outside diameter. A thermo spray of carbide and boride particles in a cobalt binder give a hard (58-60 RC) homogeneous impervious surface for abrasive and corrosive conditions.
- Electro-nickel plated threads and/or bores to improve performance in extreme corrosive conditions.
- Pin-end plungers can be supplied with Monel pins.
