Dual Fuel Mobile Frac Pump Specifications

Dragon Product’s MTU 4000 Dual Fuel Mobile Frac Unit is designed for continuous duty operations with a 2-rod compression system. This allows for removal and replacement of the fluid end without losing compression and alignment of the power end. The power end tie rods will last the life of the pump and only need to be removed at the power end overhaul. Fluid end tie rods may need periodic replacement (though this is far less than the legacy style stay rods).

The major components of our mobile frac units were chosen and designed to give you longer life before having to rebuild or refresh the power end. Routine maintenance schedule to extend the life of the power end is highly recommended.
