What is a Double-head valveless ceramic plunger pump?

In industries that require high-precision fluid handling, such as pharmaceuticals, chemicals, and cosmetics, the double-head valveless ceramic plunger pump has become an essential solution. With its outstanding durability, chemical resistance, and volumetric accuracy, this pump is widely used for precise dosing and continuous fluid transfer in various applications.

This guide explores the pump’s structure, working principle, applications, key advantages, troubleshooting, and maintenance tips to help businesses make informed purchasing decisions.


Structure & Working Principle

1. Structural Features

  • High-purity ceramic plungers: Made from 99.9% alumina and zirconia, ensuring superior wear resistance and chemical stability.
  • Pump chamber sleeve: Optimized for accurate flow control and minimal fluid retention.
  • Double-head configuration: Enables simultaneous dispensing of two different fluids or improves efficiency in high-throughput applications.
  • Valveless design: Eliminates clogging issues commonly found in traditional valve-based pumps.
  • Sealing system: Ensures leak-free operation and long-term performance stability.

2. Working Principle

The ceramic plunger reciprocates within the pump chamber, creating a suction phase that draws in liquid and a compression phase that discharges it with high precision. The valveless mechanism streamlines the fluid path, reducing turbulence and maintaining consistent volumetric accuracy.
