Spare Parts

TD 0503 is a genuine Texsteam plunger and displacement mechanism component for chemical injection pumps in the 1200, 3700, 4300, 5000, and 5100 Series. The TD-series parts include plungers, pistons, stuffing box components, and related drive-end hardware — the elements directly responsible for creating the measured pressure stroke that drives chemical dosage accuracy.In positive displacement metering applications, plunger integrity is critical. Even minor wear in the plunger or packing area results in slippage, lost prime, or incorrect dosage of corrosion inhibitors, scale preventers, or methanol into oil and gas pipelines. The TD 0503 maintains the precise bore-to-plunger fit specified by Texsteam engineering, ensuring that flow rate calibration remains stable across changing suction and discharge pressures.Designed for upstream and midstream oil and gas environments, Texsteam TD components are produced at the Houston, Texas manufacturing facility under the Baker Hughes / Dresser quality standard that has defined chemical injection reliability since 1937. Replace worn plunger assemblies with the factory-correct TD 0503 to restore full pump efficiency and protect your pipeline treatment program.
