Need Technical Support on Metering Pump Selection?

Our experts can help evaluate flow requirements, liquid end configurations, diaphragm options, and system compatibility for your application.

Metering pumps play a critical role in applications where precision, reliability, and controllable flow are essential.

Understanding how these pumps work—starting with the basic operating principles, then advancing through liquid end configurations and diaphragm technologies—is key to selecting the right design for chemical dosing, injection, and process control.

This multi‑part series provides a structured, step‑by‑step overview of metering pump fundamentals.

  • Part I covers the essential operating principles and pump mechanics.
  • Part II explores liquid end designs and how they influence performance and chemical compatibility. 
  • Part III examines metallic diaphragm liquid ends for high‑pressure or critical‑service applications.
  • Part IV introduces high‑performance diaphragm technology engineered for maximum safety, durability, and accuracy.
