TRINITY Pumpworks designs, develops, and manufactures state of the art pumping equipment and pump consumables. Our pumps are specifically designed to meet the needs and challenges of some of the most demanding industries, including horizontal directional drilling and well stimulation (fracking).
We have more than 25 years of experience in the development and manufacture of pumps designed to serve the needs of specific industries. We aren’t a “one-size-fits-all” pump supplier. By designing pumps based on deep industry knowledge, we provide you with innovations that will help you to operate more efficiently and save money.

Our team has been active in Horizontal Directional Drilling since the mid 90’s. We have repaired and manufactured components for every model of FMC, Kerr, Weatherford, Aplex, Speck, and Myers pump ever mounted on a production series horizontal directional drilling rig. For these brands, it has always been the same philosophy: take a pump designed for another industry and bend it to work in HDD. We have worked with and lived with our HDD friends and customers around the world. TRINITY is one of only two companies in the world who manufacture a line of pumps DESIGNED EXCLUSIVELY for HDD. Our experience with handling abrasive slurries and designing & manufacturing reciprocating pumps and components for HDD made it a natural transition for us to enter the Well Stimulation market.  We have developed new technology to improve the efficiency and life of blender pumps used in fracking.
