Since 1919, Triangle Pump Components, Inc. (Triangle®) has built a reputation for manufacturing efficient, long-lasting, and dependable pump products. While our company got its start making industrial products for railroads and powerhouses, we were soon asked to design and manufacture a more durable, efficient valve disc to withstand the pressure of steam pumps.

Our Durabla® pump valve, patented in 1921, quickly experienced major growth as it was heavily used during the “steam pump” era of the U.S. industrial expansion of the 1930s, 40s, and 50s. Because of the Navy’s heavy pump valve usage during World War II, Triangle Pump Components assisted in overall U.S. effort.

Since that time, Triangle®’s product line has expanded to include a diverse range of plungers, valves, and other pump components. Our products are used in a wide variety of processing industries such as oil production and refining, chemical, metals, food processing, high pressure water blast, and sewer cleaning, to name a few.
