When you specify a Schlumberger surface pump unit, you know you’ll get the highest quality and service. Manufactured in a facility certified for API Specifications 11E, 11B, and Q1; ISO 9001 and 14001; and OHSAS 18001, our products met or exceed minimum requirements for the oil and gas industry. Our pumping units are made for long run life using state-of-the-art gear-hobbing machines with quality assurance in our gearbox testing facility. All of our gearboxes are tested for noise, vibration, and bearing heat rise under load, a more stringent standard than conventional testing of free-spinning braking time. All bearings undergo third-party quality inspection to ensure they meet our specifications.
All of our welders are qualified with AWS D1.1 structural welding certification, and all are requalified annually using the radiography qualification test, a more challenging requirement than the simple bend test.
Some of the critical long welds on the structure are performed by robots to ensure consistent and repeatable weld quality.
All of these manufacturing quality steps help explain why Schlumberger pumping units consistently achieve high lifetime with minimal opex.
