AFGlobal’s DuraStim® hydraulic fracturing pump is a trailblazing advance in pump design and performance. Its advantages for high-pressure, continuous duty operation also extends to a broad scope of offshore pumping applications.
This 6,000 HP pump—triple that of conventional pumps—has 6 individual pump units integrated by a computerized control, synchronization, and automation system that varies pump rate hydraulically. A constant speed, zero emission 6,600 VAC motor and six hydraulic rotary pumps drive the system. Electric and turbine drives optimized by constant speed operation results in high gains in fuel efficiency, reduced emissions and noise.
DuraStim offers a 48-in. stroke and a low cyclic rate of 20 cycles per minute or less compared to 200 cycles per minute with conventional pumps for significant reduction in frac-spread complexity, and improving wellsite logistics and safety.
