Green Duo Piston

The Green Duo piston is a bonded dual durometer piston that is highly resistant to abrasion and tear. The bonded construction resists extrusion under pressure and restricts movement to reduce the build-up of heat.

 

The Green Duo piston is recommended for systems with oil or synthetic based mud. It is also recommended for water based muds when weights are 11 lb/gal or over. The Green Duo piston is not recommended for clear water or seawater pumping due to the lack of lubricity of these fluids. As in all urethane pistons, the backflush requirement is recommended at 14 gal/min or greater for each piston.

 

Features:

-Temperature resistance up to 180˚F (82˚C)

-Can be operated in pressures up to 6300 psi

-Backflush requirement is 14 gal/min or greater for each piston

-Not recommended for clear water or seawater pumping due to lack of lubricity of these fluids
