Metering Pumps

Chemical metering and dosing pumps for precise, repeatable injection — water treatment, pH control, chlorination, and process dosing. Accuracy depends on the right head material, diaphragm, and flow range for your chemical and back-pressure, so each model is listed with its turndown, max flow, max pressure, and wetted materials. Metering pumps dose most accurately when paired with the right pulsation dampener to smooth the pulse and steady the injection rate — which we also stock. Specs, datasheet, and price on every page. Texas-based with short lead times and US support — match the dosing range to your application and order online.

Pair any metering pump with a pulsation dampener to steady the injection rate and protect downstream instruments.
