Plungers

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.
