Structure Description: Micro Diaphragm Vacuum Pump:

The BD-05TVB incorporates advanced engineering design to produce a highly efficient and compact micro diaphragm vacuum pump suitable for various applications.

A micro diaphragm vacuum pump typically consists of a single or multiple diaphragms, which act as a separator between the drive mechanism and the compression chamber. When the volume in the chamber increases, the pressure decreases, creating a vacuum. Key components include:

  • Diaphragm: A flexible member, usually made of elastomer material, which flexes back and forth to create the pumping action.
  • Motor: Drives the diaphragm’s movement.
  • Housing: Encases all components and ensures a tight seal for vacuum creation.

This structure allows the BD-05TVB to deliver consistent vacuum levels, high efficiency, and ensures reliability and long life.
