New frac pump from Weir engineered for reliability in harsh operation
At OTC 2019, Weir Oil & Gas introduced its new SPM EXL Frac Pump - engineered from the ground up to be the most durable, longest-lasting 2500 horsepower pump on the market, the company states. With the highest rod load rating in its class at 238,000 pounds, this pump is designed to withstand today's harshest fracking conditions and ease maintenance for operators' field teams.
Weir engineered the SPM EXL Frac Pump to address major challenges operators currently face: the need for longer pumping hours with extended maintenance cycles and irregular maintenance practices caused by inexperienced field teams struggling to maintain an ever-growing inventory of equipment. To build a pump capable of withstanding the inevitable abuse of today's operations, Weir examined the most common failure modes of frac pumps and designed targeted engineering solutions to address them. Throughout the development process, Weir applied key learnings garnered from its flagship SPM QEM 3000 pump, resulting in a pump more reliable than any other in its class.
The new pump frame is constructed with an integrated skid designed to reduce vibrations across the frame and increase stiffness, thus reducing stress on the weld. The frame also drastically reduces the number of internal groove welds to reduce cracking. All welds are located on the outside of the frame, making them more accessible.
To address the higher stresses put on the gear system from high torque encountered when operating at high rod loads, Weir completely redesigned the gears and pinions utilizing the latest manufacturing techniques to provide greater surface area contact on the bull gears and reduce the risk of stripping them.
Additionally, a key focus of the new pump is to reduce the amount of onsite maintenance required for operators. To accomplish that goal Weir introduced the SPM Everbore, a hardened steel packing bore which eliminates wash boarding and protects against packing bore wash so there is no need to re-sleeve. It is designed to last the entire lifetime of the fluid end and is intended to eliminate maintenance in the red zone.
"This pump is a true testament to how Weir leverages our engineering expertise to offer our customers a pump with the highest rod load rating in its class with unmatched reliability," said Paul Coppinger, President, Weir Oil & Gas. "We are committed to driving towards having zero maintenance in the red zone, and this newly engineered pump represents innovation and progress toward that goal for our customers."
Weir's new SPM EXL is designed as a drop-in replacement for existing QWS 2500 pumps and other 2500 pumps, eliminating the need for trailer retrofits. The pump also simplifies maintenance and repair with maintenance guides and information printed directly on the fluid end. Training videos will be available end of Q2 2019.
The pump is supported by Weir Edge Services, Weir's global service offering. With service and training centers in every U.S. basin and every part of the globe, Weir Edge Services supports operators with a three-pronged approach that includes global access to engineering experts, engineered repairs, highly skilled aftermarket support, and industry-leading digital empowerment tools for Weir and other OEM equipment.
