A diaphragm is a new type of vacuum pump, with functions of both vacuum pump and compression. It can run continuously without oil, with the advantages of low noise, high working efficiency and long service life. So how to use a diaphragm vacuum pump? Let’s discuss it in detail below.

How to Install a Diaphragm Vacuum Pump?

  1. Please disconnect the power supply before installation or maintenance, otherwise it will cause electric shock or casualties.
  2. In order to avoid electric shock, do not use this product in an environment that is in contact with water or other liquids. In case of rain or snow, be sure to protect the machine.
  3. The wiring of the motor should be configured in accordance with local power regulations.
  4. Check that the local voltage matches the unit (see nameplate). If the voltage is not the same, please use a transformer
  5. During the use of this product or just after using this product, please do not touch the motor casing to avoid hot hands.
  6. No lubrication required.
  7. The size of the connecting hose needs to match the air inlet
  8. Install our supplied silencer at the air outlet.

Precautions for Using a Diaphragm Vacuum Pump

  1. It can only be used to pump air.
  2. It is forbidden to let corrosive liquid or granular materials enter the water vapor in the pump. Oil contaminants or other liquids must be filtered out firstly.
  3. Working environment temperature can not exceed 55℃.
  4. It cannot be used at high altitudes, where low pressure will influence its performance.
  5. It should be kept from dirt and moisture as a precise instrument.

Simple Troubleshooting of a Diaphragm Vacuum Pump

Disconnect the power supply before repairing the machine. If the motor does not run, or if it starts running slowly under pressure, turn off the switch and disconnect the power. Make sure the power supply is same as the power supply shown on the nameplate. Check the plug, the wire and the switch to see if there is any aging and falling off. If the pump is overheated or the noise is too high, stop running immediately and repair it.

Possible reasons

Low pressure Low vacuum degree Too much noise Overheat

Unable to start 

The valve is dirty

Valve plate is damaged

Diaphragm is damaged

Low voltage

Voltage is not matched

Start with pressure

Regulating valve is loose

Rubber leakage
