Weir’s SPM EXL Frac pump for harsher fracking conditions

weir exl pumpWeir Oil & Gas has introduced its SPM EXL Frac Pump at OTC 2019

The SPM EXL Frac Pump aims to address major challenges operators currently face such as 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.

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 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 major 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 at Weir Oil & Gas.

The SPM EXL Frac Pump is supported by Weir Edge Services, Weir’s global service offering. With service and training centres in the US 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.
