OTC Technology Review: Gardner Denver
Published by Nicholas Woodroof,
The Offshore Technology Conference (OTC), held each year in Houston, Texas, US, is one of the world's leading upstream oil and gas events. Before OTC 2020 was cancelled due to the COVID-19 pandemic, Oilfield Technology contacted a range of key players in the upstream industry and asked for their insight on the latest technologies that were due to be showcased at this year's OTC.
In this submission, Jeremy Holberg, Gardner Denver, USA, looks at a new frac pump designed for the wide variety of fleets currently operating in the frac market.
Gardner Denver Petroleum & Industrial Pumps (P&IP) recently launched the Thunder 5000 Quintuplex frac pump (Thunder 5000).
The pump is designed for the wide variety of fleets operating in the frac market, including diesel, electric, dual fuel, and gas turbine-driven, and is available with a variety of gear box designs that allow the user to optimise performance regardless of driver technology.

At 5000 hp with an 11 in. stroke length, the pump provides equivalent pressure and flow output at slower speeds, which substantially increases pump life and reduces consumable expense.
- Maximum input: 5000 hp.
- Maximum rpm: 300.
- No. of cylinders: 5.
- Stroke length: 11 in. (279 mm).
- Rod load: 250 000 lb.
- Pump weight: 26 000 lb.
- Gear ratio: Standard 7.525: 1 (other ratios are also available).
Fluid-end technology showcases a stainless steel construction and geometry that minimises stress. The Falcon spring retainer allows for rapid valve changes with no alignment requirements or special tools. An optimised crankshaft design results in minimal vibrations.
The selection of a stainless-steel fluid-end allows for maximum extended life and corrosion resistance in harsh fraccing conditions. As the lightest pump in its class, it comes with a GD-3000 planetary gearbox with a 28 in. offset for mounting flexibility.
The pump, with an appropriate gear ratio, will perform at the maximum horsepower with a variety of drivers. While some exploration and production companies are experimenting with e-fraccing, dual fuel fleets and gas turbines, many are continuing to use traditional diesel drives. The pump can be applied to all of these use cases.
Pump life is extended in the harshest of conditions through the use of Redline Series Consumables.
The company believes that the future of frac fleet design is geared towards achieving higher horsepower while utilising a suite of alternative drivers. Whether it be diesel, dual fuel, electric motor, or gas turbine, the Thunder 5000 is designed to deliver a high performance without sacrificing flexibility or reliability. The flow and pressure delivered by the 11 in. stroke reduces the number of trucks necessary in the fleet, leading to substantial cost savings. Meeting or exceeding competitor output capabilities at lower operating speeds helps extend pump life.
