Component Specifications

Definition
The fluid chamber is a precisely engineered housing within a pump head that contains the working fluid during the pumping cycle. It serves as the primary containment volume where fluid pressure changes occur, facilitating the transfer of liquids from the inlet to the outlet. This component is designed to withstand varying pressures, temperatures, and chemical exposures while maintaining structural integrity and preventing leaks.
Working Principle
The fluid chamber operates by creating a sealed environment where fluid is temporarily contained during the pumping process. As the pump mechanism (such as a piston, diaphragm, or impeller) moves, it alters the chamber's volume, creating pressure differentials that draw fluid in and expel it out through designated ports. The chamber's geometry and surface finish are optimized to minimize turbulence, pressure drops, and wear.
Materials
Typically constructed from corrosion-resistant materials such as stainless steel (e.g., 316L), cast iron, bronze, or engineered polymers (e.g., PTFE, PEEK) depending on application requirements. Material selection is based on factors like chemical compatibility, pressure ratings (e.g., up to 5000 psi), temperature range (-20°C to 200°C), and wear resistance.
Technical Parameters
  • Surface Finish Ra 0.4-1.6 μm
  • Pressure Rating Up to 5000 psi
  • Volume Capacity 50-5000 ml
  • Connection Types Flanged, threaded, or clamped
  • Temperature Range -20°C to 200°C
Standards
ISO 2858, DIN 24256

Frequently Asked Questions

What is the primary function of a fluid chamber in a pump head?

The fluid chamber serves as the containment volume where fluid is temporarily held and pressurized during the pumping cycle, enabling controlled fluid transfer from inlet to outlet.

How do material choices affect fluid chamber performance?

Material selection determines chemical resistance, pressure tolerance, temperature stability, and wear characteristics. For example, stainless steel offers corrosion resistance for chemical applications, while polymers provide cost-effectiveness for less demanding environments.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
