Since 1919, Triangle Pump Components, Inc. (TPCI) 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.

Plunger Packing and Stuffing Box Components
Packing plays a major role in the assurance of adequate down-stream pressure. The packing provides a seal around the extension rod, plunger or piston. For a piston the packing is contained in a groove in the piston and moves with the piston. For an extension rod or plunger the packing is stationary and is contained by the stuffing box.

Valve Puller
All Triangle Pump Components valve units are designed for easy installation with minimum disassembly. When inspection shows that wear has occurred, however, proper maintenance such as replacing the valve disc, spring, and sleeve, or torqueing studs, bolts, and locknuts may be required. We also recommend re-facing or reinstalling the seat to eliminate any ridges at the inner or outer edges.
