Texsteam TD 0348-0 – Plunger Mechanism Part for Chemical Injection Pump

TD 0348-0 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 0348-0 maintains the precise bore-to-plunger fit specified by Texsteam engineering, ensuring that flow rate calibration remains stable across changing suction and discharge pressures.
