It can pump cement slurries with densities up to 2,200 kg/m³ (20 ppg) and a rate of 2.8 m³/min (18 bbls/min).

The twin cementer also features a high-energy closed mixing system capable of pumping high-density cement slurries at high rates. The automated direct bulk-fed mixing system provides density control and eliminates operator error, as well as providing a dust-free and environmentally sound work area. The state-of-the-art control cab gives provides safety, communications capability, and crew comfort in all environments while ensuring control system integrity.
