Top 5 Accessories for Micro Pumps

Table of Contents

In my experience, it is very necessary to match the accessories of the miniature pump.

The 5 most frequently used miniature pump accessories are: filter, check valve, tube, muffler, bracket. Use them to increase pump life, reduce pump noise, prevent gas backflow, and other effects.

This article will introduce 5 common miniature pump accessories to help customers better choose a pump.

Filter

micro vacuum pump filters

Micro air pump/vacuum pump filter is to collect the contaminants (mainly dust) inhaled by the atmosphere to prevent system contamination.

  • Advantage: Can be used for positive pressure, but also for negative pressure (vacuum)
  • Disadvantages: Need to replace the filter element
  • Purpose: To avoid or reduce impurities into the pump head

BODENFLO pump accessories purchasing guide?

To save time and money, please allow me to introduce more fully how to match the accessories of BODENFLO pumps.

BODENFLO has four types of product series.

Miniature diaphragm air pumps

  • BD-01, BD-02,BD-03, BD-04 series (for gas and vacuum)
  • Advantages: small size, light weight, low noise.
  • Suggestion 1: In order to ensure that the diaphragm and valve plate is not contaminated by impurities (dust), which affects the parameters. Especially for diaphragm vacuum pumps, it is recommended to add a pre-filter.
  • Suggestion 2: To prevent backflow of gas, it is recommended to add a check valve.
  • Suggestion 3: BD-02 and BD-03 series use silicone brackets for fixing and vibration damping.

Miniature diaphragm liquid pump

  • BD-01, BD-02,BD-03, BD-04 series (for water, liquid)
  • Suggestion 1: In order to ensure that the diaphragm and the valve plate are not contaminated by impurities (dust), which can affect the parameters. Especially for diaphragm vacuum pumps, it is recommended to add a pre-filter.
  • Suggestion 2: In order to prevent liquid backflow, it is recommended to add check valve.
  • Suggestion 3: BD-02 and BD-03 series use silicone brackets for fixing and vibration damping.

Small piston air pump

  • BD-07 series (for air, gas)
  • Advantage: high pressure, high flow rate.
  • Suggestion 1 : Add muffler to reduce noise.
  • Suggestion 2 : Use PU air hose for high pressure resistance.

Small air compressor

  • BD-08 series (for air, gas)
  • Advantage: High pressure, high flow rate.
  • Suggestion 1 : Add muffler to reduce noise.
  • Suggestion 2 : Use PU air hose, strong pressure resistance.
