Dosing & Metering Pump

Dosing & Metering Pump Manufacturer

Metering and Dosing Pump
Metering and Dosing Pump
A high-precision positive displacement pump engineered for accurate, consistent, and controlled chemical injection across industrial, water treatment, pharmaceutical, and process applications.

Product Overview

Our Metering / Dosing Pump is engineered for industries that demand precise, consistent, and controlled fluid injection. Designed to handle chemicals, additives, acids, alkalis, polymers, disinfectants, and process fluids, this pump ensures high accuracy, repeatability, and reliability in every dosing application.

Built with corrosion-resistant materials and advanced mechanical design, the metering pump provides stroke-by-stroke accuracy and stable performance even under varying pressure and temperature conditions. With both mechanical diaphragm, hydraulic diaphragm, and plunger dosing designs, this pump is suitable for low to high-pressure dosing across water treatment, chemical processing, pharmaceutical, and industrial applications.

The Metering / Dosing Pump is a high-precision positive displacement pump designed for exact chemical injection. Its micro-adjustable stroke mechanism and optional Variable Frequency Drive (VFD) allow fine-tuned control over dosing volume, ensuring accurate delivery even at low flow rates.

The pump is constructed with chemically compatible materials such as PP, PVDF, SS316, PTFE, PVC, and other engineering plastics depending on the medium being handled. Advanced diaphragm technology eliminates leakage, reduces pulsation, and ensures reliable operation.

Because dosing applications require accuracy, consistency, and fail-safe operation, the pump is equipped with overload protection, non-return valves, and stable linear stroke adjustment to maintain accuracy within ±1% of set capacity.
