About Welker

Welker has come to be recognized as a world leaderin quality and innovative equipment for the oil and natural gas industry. Welker has set the standard in the sampling industry for more than 50 years. While we are proud of all we have accomplished in that time, we are even more excited about the challenges we face in taking the company to greater heights.

Brian H. Welker takes over as Chairman of the Board and CEO following the December 2007 retirement of his father, Robert (Bob) H. Welker, P.E., who established the company in 1958. The company’s President and CEO for 23 years, Brian brings a wealth of knowledge, experience and leadership that has allowed the company to generate new, quality products each year.

Headquartered in Sugar Land, Texas, Welker is one of few family owned companies in our sector of the oil and gas industry, offering customers flexibility that larger companies can’t match.

With representatives in more than 50 countries, Welker’s broad representation helps ensure that customers receive support that is both exceptional and accessible.

While the majority of our customers are within the oil and gas industry, Welker engineers products for the environmental and medical fields as well as cement and waste water recovery.

At Welker, our priority is to focus on the service and attention we provide to each customer and the quality and innovation of the products we manufacture in fulfilling the complex needs of our industry.

That has been our way for three generations and will continue to be for generations to come…
